Details: PPC-M51


The device is used for absolute pressure and gauge pressure measurement in gases, steams or liquids.

The device has a capacitive measuring cell and a ceramic process isolating diaphragm.

The ceramic sensor is a dry sensor. The process pressure acts directly on the robust ceramic process isolating diaphragm and deflects it. A pressuredependent change in capacitance is measured at the electrodes of the ceramic substrate and the process isolating diaphragm. The measuring range is determined by the thickness of the ceramic process isolating diaphragm.

The data is transmitted to the control via analog signal, HART protocol or PROFIBUS PA.

The device is easily configured by the use of keypad or with the PACTware configuration software.

The device is designed modular and offers a variety of process connections, a replaceable display and a universal electronics.
