INTRODUCTION



Thank you for choosing the HPC50 Series intrinsically safe handheld pressure calibrator from Crystal Engineering Corporation. HPC50 calibrators feature dead-

weight tester accuracy in a modern digital package with the safest tting connection available. The full color display features an easy to use interface and may

be used in a broad range of applications fr

om simple tool type jobs to complex calibration jobs in custody transfer systems.

Overview  1

Accuracy is up to 0.035 percent of reading

temperature compensated

Single and dual pressure sensor models are available from vacuum up to 10 000 psi / 700 bar. In addition, the HPC50 features the ability to add up to two

external pressure ports (APMi) to provide up to four 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 HPC50 also includes inputs for mA, voltage, switch testing, and up to two temperature measurement modules (ATMi).

PRESSURE SENSORS



The HPC50 Series is equipped with one or two pressure sensors. In addition, one or two intrinsically safe APMi (Advanced Pressure Module) or ATMi (Advanced

Temperature Module) external modules may also be used. For information on the Crystal external modules, please refer to APMi Modules and ATMi Modules.

Be sure to choose the proper sensor based on working pressures and accuracy.

WARNINGS: The following warnings apply to any sensor used with the HPC50 — whether internal or external:

CPF o-ring size and material: AS568A-012, Viton 80 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 uid 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 ttings. Please note this is only a fraction of the typical torque

required to seal a 1/4” NPT tting. If a torque wrench isn’t practical to use, the ttings can be assembled as follows: Hand tighten tting fully

Operation  12

Using the Tare function improves your dierential measurement uncertainty signicantly if used properly. The Tare function equalizes (normalizes) the

HPC50’s two modules at a non-ambient datum.

If you apply the same static line pressure to both sensors simultaneously, you should have a dierential 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 dierential reading is zero. This gives you a

more accurate dierential 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 ΔP 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 ΔP reading until cleared with the Tare button.

Percent Error Function

The HPC50 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 dicult to set an exact pressure with an external pump. The HPC50 simultaneously displays pressure, mA, and percent error.

Percent Flow Function

The HPC50 can calculate the ow percentage for a dierential pressure transmitter. The square root of the dierential pressure across an orice plate is pro-

portional to the ow. The dierential pressure is simulated or measured via the mA current and the resultant calculations are then scaled from 0 to 100%.

APMi modules must be exercised and re-zeroed whenever exposed
to signicant changes in environmental conditions to achieve these
specications. To exercise a module, cycle the module between zero
(ambient barometric pressure) and the pressure of interest. A properly
exercised module will return to a zero reading (or return to the same
ambient barometric reading).

The proper selection of the RTD sensing element is very important as the error associated with this device is the majority of the overall system measurement uncertainty. IEC 751 is the
standard that denes the temperature versus resistance for 100Ω, 0.00385 Ω/Ω/°C platinum RTDs. IEC 751 denes two classes of RTDs: Class A and B. Class A RTDs operate over the -200 to
630°C range versus -200 to 800°C for the Class B elements. For example, the Class A uncertainty is about half that of the Class B elements as illustrated in the following table.

TROUBLESHOOTING



The HPC50 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.

Reason

Gas (usually air) is trapped in the line between the

the combination of gas and uid is acting like a spring. At higher pressures (above 2000 psi, typically) this may eventually diminish, as the gas dissolves into

the uid.

X

Solution

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

HPC50

Non-repeatability of pressure measurements

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

X

Reason

As in the previous note, gas has dissolved into the hydraulic uid. When decreasing the pressure, the dissolved gas then leaves the uid, but at an uneven rate,

so a small pressure dierential (due to uid head pressure) may exist between the reference deadweight and the gauge being tested.
