Portable process calibrator CPH7000.The model CPH7000 process calibrator is a precise, portable calibrator for the calibration and checking of analogue pressure measuring instruments, pressure transmitters and process transmitters. The 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.

■ Calibration service companies and service industry

■ Measurement and control laboratories

■ Quality assurance

■ On-site calibration (safety also in hazardous areas)

The calibrator offers the possibility to set calibration routines

quickly and easily, but also to 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.

■ Manual pressure generation of -0.85 … +25 bar[12.3 ... +360 psi]

■ Accuracy: 0.025 % FS (incl. calibration certificate)

■ Generation/measurement of 0 ... 24 mA and voltagesupply DC 24 V

■ Data logger with high measuring rate and large memory

■ Intrinsically safe version

The CPH7000 optionally features an integrated reference pressure sensor and also a manual pressure generation, with which pressures of -0.85 ... +25 bar [12.3 ... +360 psi] can be generated. It is possible to simultaneously power an external transmitter via the electrical module and to measure (or also simulate) its output signal.The CPH7000 is temperature compensated and achieves an accuracy of 0.025 % of span. In order to avoid intricate calculations, the measured values can also be displayed directly in customer-specific units.
