CPH7000 Portable Pressure Calibrator

The WIKA CPH7000 portable pressure calibrator is a precise, portable calibrator for the calibration and checking of analogue pressure measuring instruments, pressure transmitters and process transmitters. The WIKA CPH7000 in Ex version can also be used in hazardous areas. Furthermore, pressure switches can be checked and the switching point determined. With the CPH7000, not only can transmitters be checked but also simulated and tested.

The CPH7000 optionally features an integrated reference pressure sensor and a manual pressure generation, with which pressures of -0.85 … +25 bar [12.3 … +360 psi] can be generated. It is possible to power an external transmitter via the electrical module simultaneously and to measure (or also simulate) its output signal.

Functions

The calibrator offers the possibility to set calibration routines quickly and easily and run preconfigured calibration routines and automatically save the measured values. Over the WIKA-Wireless interface, the completed calibration processes can be transmitted to a PC. This data can subsequently be evaluated and archived using WIKA-CAL software. Thus a completely paperless transmitter calibration is possible with just the CPH7000.

Accuracy

The CPH7000 is temperature compensated and achieves an accuracy of 0.025 % of the span. To avoid intricate calculations, the measured values can also be displayed directly in customer-specific units.
