CPH7000

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

Design

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.

Functions

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 the WIKA-CAL software. Thus a completely paperless transmitter calibration is possible with just the CPH7000.

Accuracy

The CPH7000 is compensated over a wide temperature range of 10 … 50 °C (50 … 122 °F) and achieves an accuracy of 0.025 % of span. To avoid intricate calculations, the measured values can also be displayed directly in customer-specific units.

Complete service case

The process calibrator, developed specifically for maintenance and service operations is delivered in a portable case system and, depending on requirements, can be equipped with, for example, model CPT7000 external pressure sensors, a Pt100 temperature sensor or a portable a system with storage bag.

Software

The calibration software for the CPH7000 is WIKA-CAL. WIKA-CAL, alongside PC-supported calibration and the logger function, also offers the management of the calibration and instrument data in an SQL database. The data transfer is achieved completely wirelessly via WIKA-Wireless.
