Function

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

The device has a piezoresistive measuring cell and a metallic welded process isolating diaphragm.

The operating pressure deflects the process isolating diaphragm. A fill fluid transfers the pressure to a resistance bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

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.
