CPH7000 Portable Pressure Calibrator

The CPH7000 in Ex version can also be used in explosive atmospheres. In addition, pressure switches can be checked with trip point determination. With the CPH7000, transmitters are not only checked, but also simulated and tested.

The CPH7000 is optionally equipped with an integrated reference pressure sensor and a manual generation pump, to generate pressures of -0.85 … +25 bar (12.3 … +360 psi). It is possible to simultaneously power an external transmitter via the electrical module, and to measure (or simulate) its analog signal.

The calibrator offers the possibility to set up calibration procedures quickly and easily, but also to launch pre-configured calibration procedures, and to automatically save the measured values. Via the WIKA-Wireless interface, the complete calibration results can be transferred to a PC. These data can then be evaluated and archived using the WIKA-CAL software. Thus, a full calibration of the transmitter can be done with just the CPH7000, without the use of paper.

The CPH7000 is compensated over a wide temperature range and offers an uncertainty of 0.025% of range. In order to avoid complicated calculations, the measured values can also be displayed directly in customer-specific units.
