PORTABLE PROCESS CALIBRATION High-pressure measuring instruments can now also be tested in the field
Last month, measurement technology specialist WIKA launched the CPH7000 portable process calibrator, which is the first hand-held instrument from WIKA that records measured values of up to 10 000 bar.
With the CPH7000 portable process calibrator, high-pressure measuring instruments can now also be tested in the field, where compressors and pump systems are in operation.
For such measuring tasks, the portable calibrator uses the WIKA CPT7000 high-pressure sensor as an external reference. Its rupture-proof, thin-film cell is not welded. It is inserted tightly into a tapered pressure channel and is thus also insensitive to dynamic pressure profiles.
Through the combination with this sensor, the already broad range of applications for the CPH7000 is expanded even further. The calibrator is a portable multifunction instrument with an integrated electrical module, a hand pump to generate test pressures up to 25 bar and a high-performance data logger. In addition to the calibration of process transmitters and pressure gauges, the same instrument can fulfil test tasks for the measurements of temperature, voltage and current.
The safety-related quality of the CPH7000 is also accredited internationally through the Standards Council of Canada (CSA) “Safety” approval. The CSA registered mark shows that a product has been independently tested and certified to meet recognised standards for safety or performance.
