JOFRA DPC-500 Series - Documenting Pressure Calibrator

With the high resolution, compact JOFRA DPC-500 documenting pressure calibrator new standards are reached within pressure calibration. Designed for high precision calibration of pressure instruments such as pressure gauges, transmitters, digital manometers, pressure switches and overpressure valves, the DPC-500 offers improved pressure accuracy (± 0.025% FS), better electrical current (± 1.6 μA) and voltage (± 0.5 mV) accuracy and an extended pressure range of 250 mbar to 1000 bar FS. The DPC-500 also offers absolute pressure measurement from 0.4 to 16 bar absolute.

Communication og documentation
The easy to use, menu driven user interface is available in 5 languages. Calibration procedures can be pre-defined and used for on-site calibration. Up to 16 calibration procedures, each with 22 test points can be stored. The results can be uploaded to a PC via the supplied DPC-CAL software package, which transfers calibration data into a predefined Microsoft Excel™ worksheet. This includes predefined certificate print out for full documentation.

Reference sensor
In a new approach to pressure calibration, the DPC-500 has a separate reference pressure sensor which can be fixed to instrument or used “off instrument” via a cable. Up to 5 reference sensors of different pressure ranges may be used with any one instrument. The JOFRA DPC-J series are high precision reference sensors with accuracies to ± 0,025% FS (0 to 50 °C including non-linearity, hystereses and repeatability).

System A - Pneumatic hand pump - T-960 and T-970

Model T-960 pneumatic pressure pump features an extended range vernier adjustment for precisely controlling pump pressure and comfortable pistol grip handle.
Model T-970 pneumatic pressure pump is similar to the T-960, but generate pressure up to 40 bar (580 psi).

Pressure range, T-960 0 to 2 bar / 0 to 30 psi
Pressure range, T-970 0 to 40 bar / 0 to 580 psi

System B - Pneumatic hand pump - T-975

Model T-975 pneumatic pressure pump features both vacuum and pressure generation. A button (valve) makes it easy to switch from vacuum to pressure measurements. Built-in release valve, vernier valve for fine adjustment and dual pressure output enable safe and simple operation. The unit offers both metric and imperial threads on the reference connection and the hose.

Pressure range -0.91 to 40 bar /-27 inHg to 580 psi

System C - Hydraulic hand pump - T-620

This easy-to-use hand pump is specially designed for high pressure applications. The pump has a built-in reservoir, vent valve, and vernier valve for fine adjustment. The pump has a dual pressure output - one for the test object and one for the IPI indicator.

Pressure range, T-620 0 to 200 bar / 3,000 psi

Pressure range, T-620H 0 to 350 bar / 5,000 psi

System D - Hydraulic screw pump - 65-PO16

The AMETEK screwpump is designed for very easy generation of high pressure.

This pump is part of system D. The screwpump has a 4 connection manifold. Fine adjustment, vernier valve, liquid reservoir, and fittings are optional. The AMETEK screwpump may be delivered for 2 different test media: hydraulic oil or water.

Pressure range 350 bar / 0 to 5,000 psi

System F - Hydraulic pump - Type T

The type T pump is designed for high pressure applications up to 15,000 psi (1,000 bar). The pump and system may be ordered with either oil or a water/alcohol mixture as the pressure medium. The pump is constructed of 300 series stainless steel and Monel allowing for the use of other hydraulic media.

The Type T pump features a dual pressure output manifold, fine adjustment vernier valve, relief valve, and dual volume control for rapid pressure increase at lower pressures and easier pumping at higher pressures.

Pressure range 0 to 1000 bar / 15,000 psi
