Portable process calibrator model CPH7000 with
optional hand pump
Description
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.
