DMK 331 Pressure transmitter for use with aggressive chemicals


The DMK 331 uses a ceramic pressure sensor and has the option of stainless steel, PVC or PVDF process connection, if the media is viscous or paste like then the sensor can be installed with the ceramic sensor face approx. 2mm from the front of the process conenction, this means that no clogging inside a pressure port can occur.

The industrial pressure transmitter DMK 331 with ceramic sensor has been especially designed for pasty, polluted or aggressive media and for oxygen applications at low pressure range.

As with all industrial pressure transmitters supplied by Impress Sensors, you may choose between various electrical and mechanical connections also on DMK 331 to best suit the application.
