General information
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. 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.
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 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. In order to avoid intricate calculations, the measured values can also be displayed directly in customer-specific units.
Features
For pressures greater than 25 bar (362.6 psi), there are the model CPT7000 external pressure sensors.
Thus pressure measurement and calibration is possible in further pressure measuring ranges and accuracies.
An optional atmospheric module records and documents the environmental parameters important for a calibration, such as atmospheric pressure, air humidity and ambient temperature.
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 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.
Certified accuracy
For the model CPH7000 process calibrator, the accuracy is certified in a factory calibration certificate accompanying the instrument. On request, we can provide a DKD/DAkkS calibration certificate.
