Руководство по эксплуатации «HPC40 Series» (Код не указан!)

Thank you for choosing the HPC40 Series handheld pressure calibrator from Crystal Engineering Corporation. HPC40 calibrators feature deadweight tester accuracy in a modern digital package with the safest fitting connection available. The new full color display also features a new easy to use interface similar to the one used in the JOFRA ASC-400 Series. The HPC40 is available as a stand-alone calibrator or in one of our complete pump systems, and may be used in a broad range of applications from simple tool type jobs to complex calibration jobs in custody transfer systems.

Accuracy is up to 0.035 percent of reading—so one HPC40 can typically replace several gauges or calibrators you may have been using. The HPC40 is fully temperature compensated—so there is no change in accuracy throughout the entire operating temperature range!

Single and dual pressure sensor models are available from vacuum up to 15 000 psi / 1000 bar. In addition, the HPC40 features the ability to add an external pressure port (APM) to provide up to 3 pressure ports. When included with a barometric reference (BARO option), all pressure readings can be displayed as gauge or absolute readings.

In addition to pressure measurement, the HPC40 also includes a full set of electrical connections. Inputs are included for mA, voltage, switch testing, and temperature measurement (RTD). An internal 24 VDC supply is also included to power mA transmitters.

The HPC40 Series is equipped with one or two pressure sensors. In addition, a Crystal APM (Advanced Pressure Module) may also be used. For information on the Crystal APM, please refer to the APM CPF Series Operation Manual. Be sure to choose the proper sensor based on working pressures and accuracy.

_! WARNINGS: The following warnings apply to any sensor used with the HPC40 — whether internal or external:

• Pressure sensors may be damaged and/or personal injury may occur due to improper application of pressure. Please refer to the Ranges and Resolutions table for information on overpressure ratings.

• The calibrator will display +OL when an inappropriate pressure is applied. If +OL is displayed, the pressure should be reduced or vented immediately to prevent damage or possible personal injury.

Note: + OL is displayed when the pressure exceeds 110% of the nominal range of the sensor.

Pressure Connection

Crystal CPF System: Medium Pressure Female (MPF) (1/4” medium pressure tube system with 7/16-20 threads). See our CPF Brochure for further information.

CPF o-ring size and material: AS568A-012, Viton 80 or 90 durometer (P/N 3981).

For most applications CPF Fittings can be hand tightened (no tools required). Wrench tightening is recommended (to achieve a metal to metal cone seal) for applications where chemical compatibility of the process fluid and the o-ring are a concern. Cone seals require only moderate assembly torque to seal up to 10 000 PSI (700 bar). We recommend a tightening torque of 120 in-lbs ±20 in-lbs for our CPF fittings. Please note this is only a fraction of the typical torque required to seal a 1/4” NPT fitting. If a torque wrench isn't practical to use, the fittings can be assembled as follows: Hand tighten fitting fully until the cone has bottomed out, then tighten an additional 20° using a hex wrench. Apply a small amount of media-compatible lubricant to the gland threads and male cone to increase fitting life, reduce the likelihood of galling, and promote sealing.

_! CAUTION: To achieve CPF maximum allowable working pressures no o-ring substitutions are allowed. See our CPF brochure and CES-003 CPF Safety Guide available from the website at crystalengineering.net for further detail.

Measuring Vacuum

All versions of the HPC40 can be used to measure moderate vacuum.

When measuring pressure less than ambient barometric conditions, a minus (-) sign will appear.

_! CAUTION: The HPC40 is not recommended for continuous use at high vacuum.

HPC40 Series Operation Manual

Overpressure Conditions

The HPC40 Series will read pressure up to approximately 110% of the rated pressure range. Above 110%, the display will indicate + OL, and readings will stop updating. The zero function does not affect when the display will indicate + OL, so depending on the zero value it is possible that the display will indicate + OL without the maximum pressure being displayed.

For instance, if a 100 psi range is zeroed when 30 psi is being applied, it will indicate that the overpressure condition has been reached at 80 psi (i.e., 110% x 100 psi - 30 psi = 80 psi).

Overpressure can affect accuracy, but the effect is only temporary unless the sensor has been destroyed. See the Ranges and Resolutions table for maximum allowable overpressure ratings.

Note: The BARO sensor cannot be zeroed.

_! WARNING: This calibrator can display zero pressure when connected to a source of pressure! Do not rely on the display indication before disconnecting— it may not be indicating true pressure. Never disconnect pressure instrumentation without first relieving system pressure!

Differential Pressure

The HPC 40 Series can display differential pressure when 2 or more sensors are installed (including external APM). The modules do not have to be the same full scale pressure range.

Select Diff . Pres. from the Mode section.

Choose the two sensors that you want to use for differential pressure.

Choose the unit for the differential reading.

For more information on working in the HPC40 display, see Navigating Through a Typical Setup.

Apply pressure to one or both sensors to read the differential.

Note: The static pressure is also displayed on the bottom of the window. The unit for the static pressure does not have to be the same as the differential unit.

Tare

Using the Tare function improves your differential measurement uncertainty significantly if used properly. The Tare function equalizes (normalizes) the HPC40's two modules at a non-ambient datum.

If you apply the same static line pressure to both sensors simultaneously, you should have a differential reading of zero. Due to the allowable error tolerance for each module, the reading may not be zero. The Tare function allows you to normalize both readings so that the differential reading is zero. This gives you a more accurate differential reading than if this process were not completed.

Note: Tare should be reestablished every time your measurement conditions change, including vent condition. For instance if your ДР reading has 8 inH20 of Tare at 1500 psi static, when you return to vent condition this 8 inH20 of Tare will remain in place on your ДР reading until cleared with the Tare button.

To Tare:

• 1 Use the (arrow) buttons to navigate to the Differential Mode view.

• 2 Press the (zero) button to activate the function button options.

• 3 Press the (function) button for the ( КЕШИ ) icon.

Note: You will notice that the word Tare is now included on the top right of the display to indicate that the sensors have been tared.

• 4 To clear the Tare value in the Differential Mode, hold the (function) button for the ( ОЭВП ) icon for four seconds until the differential display readings change from (-----) to (- - -). The tare indication will now be removed from the display.

0.005

For more information on working in the HPC40 display, see Navigating Through a Typical Setup.

Connect the HPC40 using the appropriate test leads.

The HPC40 will indicate the measured voltage.

Note: The display will indicate + OL if the measured voltage exceeds the nominal range of voltage measurement (30 VDC).

Your HPC40 has the ability to measure temperature very accurately using “true ohm” technology. True ohm resistance measurement eliminates temperature reading errors by compensating for thermoelectric effects associated with the wires and connections between the RTD and the HPC40. The HPC40 will also indicate electrical resistance (Q) to help in troubleshooting your resistance based sensing element.

RTDs are characterized by their 0° C resistance, R0. The HPC40 accepts -2, -3, and -4 wire inputs, with 4 wire input being the most accurate.

The HPC40 is compatible with a large number of platinum RTD probe types. Ametek offers a platinum 100 probe that is ready to connect directly to the HPC40's RTD port. See Accessories and Replacement Parts for details.

► To Measure Temperature

• 6 The HPC40 will display the measured temperature.

Note: + OL will be displayed if the probe resistance is greater than 400 Ohms and/or the calculated temperature is outside the range defined for the probe. Temperature range depends on the probe type.

I PERFORMING A SWITCH TEST

Performing a switch test will require the use of both screens. The HPC40 records switch state, and pressure or temperature measurement at the time of switch change. After the test, the result is displayed in a convenient and easy-to-use format.

► To Perform a Switch Test

Select              in the upper display.

FOR A PRESSURE SWITCH, select P1, P2, Diff . Press., or APM in the lower display.

FOR A TEMPERATURE SWITCH, select RTD In in the lower display.

For more information on working in the HPC40 display, see Navigating Through a Typical Setup.

Connect the HPC40 to the switch using the terminals on the top of the HPC40. (The polarity of the terminals does not matter.)

FOR A PRESSURE SWITCH, connect a pump to the HPC40 and then to the switch.

FOR A TEMPERATURE SWITCH, connect an RTD to the HPC40 connection and place the RTD and temperature sensor in a temperature calibrator.

Check that the vent on the pump is open, and zero the calibrator if necessary. Then close the pump vent.

The upper display will show no read outs for the Closed, Opened, and Dead band values.

8 To perform a new test, highlight the reset option and press the (enter) button. The Closed, Opened, and Dead band value will all be blank again.

Note: The procedure is the same whether the default mode for the switch is opened or closed. So for example, applying pressure or temperature to an open switch will cause the switch to close, and the icon will change to ) as in step 7 above.

When calibrating a transmitter, both the upper and lower displays are used. Pressure and Temperature Transmitters with ranges of 0 to 20 mA, 4 to 20 mA, and 10 to 50 mA can be calibrated by an HPC40. The example below will use a 4 to 20 mA pressure transmitter.

► To Calibrate a Pressure Transmitter

Select mA In in the upper display and P1 in the lower display.

Select QnRg0mA from the Range list.

Select Ext. Pwr. from the power source list if the mA loop is already powered, or Int. Pwr. to have the HPC40 supply the power.

► HART Resistor

The HPC40 has an internal 250 Ohm HART resistor that can be selected if desired. With the (settings) button, choose BBfflBna] to select HART resistor On or Off.

► Percent Error Function

The HPC40 can be programmed to calculate a deviation or % error from 4-20 mA output. This eliminates the need for manual calculations and can also be helpful if it becomes difficult to set an exact pressure with an external pump. The HPC40 simultaneously displays pressure, mA, and percent error.

Select % Error from the mA units selection in the upper window.

Use the (arrow) buttons to set the 0 and 100% points for both the mA and pressure ranges of the transmitter.

Increase pressure to the desired point and the HPC40 upper display will indicate the % error as well as the actual mA value. The lower display will show the measured pressure.

► Scaling Function

The HPC40 has the ability to read current or voltage in the upper display that is scaled to and displayed in the same units as the lower display. This makes it much easier to compare a mA reading to a known accurate pressure reading.

Select Scaling from the mA units selection in the upper window.

Use the (arrow) buttons to set the 0 and 100% points for both the mA (or VDC) and pressure ranges of the transmitter.

Increase pressure to the desired point and the HPC40 upper display will indicate the equivalent pressure based on the mA reading, as well as the actual mA value. The lower display will show the measured pressure.

Gauge Pressure Accuracy

Includes all effects of linearity, hysteresis, repeatability, temperature, and stability with the operating temperature range for one year.

Note: Exposure to environmental extremes of temperature, shock, or vibration may warrant a more frequent calibration period.

The HPC40 Series must be exercised and re-zeroed whenever exposed to significant changes in environmental conditions to achieve these specifications. To exercise a gauge, cycle the gauge between zero (ambient barometric pressure) and the pressure of interest. A properly exercised gauge will return to a zero reading (or return to the same ambient barometric reading).

The HPC uses four AA batteries. Unscrew the two flathead screws to gain access to the battery compartment. Replace the batteries taking care to note polarity for their proper installation. Failure to properly seal the battery compartment may allow water damage that could permanently compromise the HPC40.

After installation, the HPC40 may prompt you to indicate the type of battery you installed. This is to ensure that non-rechargeable batteries are not damaged through charging when connected to the USB port.

^► USB Power and Charging

The USB/powered icon (      ) will be displayed when connected. The mini USB connection will power the HPC40 with or without batteries installed. If

rechargeable batteries are installed and the appropriate battery type selection has been made, it will also recharge the batteries.

► Ordering Information

The HPC40 Series has been tested and certified to comply with a variety of international standards.

We declare that the HPC40 is in accordance with the Electromagnetic Compatibility Directive, and the Pressure

Equipment Directive per our declaration(s).

European Signatory:

^AE^Kg^D204kAS».,.De...rk

European Signatory:

The HPC40 Series is a very high performance calibrator. Due to the high resolution of this product, you may observe conditions that appear to be defects in the product, but are in fact a result of being able to read and measure pressure to a degree not possible with other instruments.

Noisy or unstable reading when used with fluids

When calibrating or comparing the indicated pressure from an HPC40 against a hydraulic deadweight tester or piston gauge, the reading on the HPC40 may appear unstable—the least significant digit jumps up and down several counts.

^► Reason

Gas (usually air) is trapped in the line between the HPC40 and the deadweight tester. What is actually happening is the mass is oscillating up and down, and the combination of gas and fluid is acting like a spring. At higher pressures (above 2000 psi, typically) this may eventually diminish, as the gas dissolves into the fluid.

► Solution

Evacuate all tubing with a vacuum pump before introducing fluid into the system.

Non-repeatability of pressure measurements

When checking the calibrator against a hydraulic deadweight, increasing pressure measurements do not match decreasing pressure measurements.

• ^► Reason

As in the previous note, gas has dissolved into the hydraulic fluid. When decreasing the pressure, the dissolved gas then leaves the fluid, but at an uneven rate, so a small pressure differential (due to fluid head pressure) may exist between the reference deadweight and the gauge being tested.

• ^► Solution

Evacuate all tubing with a vacuum pump before introducing fluid into the system.

Slow return to zero and/or non-repeatability of pressure measurements

• ^► Reason

Pressure port is obstructed.

• ^► Solution

Clean with low pressure fluid. Do not touch diaphragm as damage will result.

HPC40 Series Operation Manual

I CALIBRATION

If adjustment is required, we recommend returning the HPC40 to the factory. Factory service offers benefits you won't find anywhere else. Factory calibration tests your HPC40 at a variety of temperatures utilizing NIST traceable standards, resulting in calibration certificates that provide performance data over temperature. Our calibration facilities are A2LA accredited (cert #2601.01) to ISO 17025:2005 & ANSI/NCSL Z540-1-1994. A2LA is internationally recognized as an accreditation body by the International Laboratory Accreditation Cooperation, ILAC. Furthermore, upgrades may be available to add or enhance operating features. We designed the product to last, and we support it so that you can get the most from your investment.

Under normal operating conditions, we recommend the HPC40 be calibrated on an annual basis. Your quality system may require more or less frequent calibration, or your experience with the gauge, or operating environment may suggest longer or shorter intervals.

Although we prefer that you return the HPC40 to us for calibration, ordinary recertification and/or adjustments may be performed by any qualified personnel with appropriate training and equipment. The following instructions are ONLY intended for such qualified personnel with appropriate test equipment. We recommend that the calibration standards used have a minimum rated accuracy of 0.008% of reading, or equivalent in terms of percent of full scale. This level of accuracy requires the use of piston (deadweight) gauges or very high performance pressure controllers.

(jOlV8Tqi.ODNTROLj There are no internal potentiometers. Each of the HPC40's sensors has a “span factor” (userspan), set to approximately 1 (as shipped from the factory). As components age this may need to be changed to a value slightly higher or lower, to slightly increase or decrease all readings. This adjustment can be made with a computer through CrystalControl.

Calibration of P1 and P2

(jOWTgi.OPNTKOLj “Zero” the HPC40, then record displayed pressure for two or more pressure points. Determine if the HPC40 would benefit from an overall increase or decrease of the indicated pressures. Adjust userspan accordingly and validate results.

Calibration for Barometric Reference Module (BARO)
