Aggressive Media Pressure Sensor | Oxygen Pressure Transducer* | DMK331

Accurate Pressure Measurement in Aggressive Media


The DMK331 industrial aggressive media pressure sensor is designed for pressure measurement in aggressive media applications from 0-400mbar up to 0-600bar. We can also provide the sensor specially cleaned for use in oxygen applications; the maximum pressure range is 0-25bar in this application.  It is ideal for use in plant and machine engineering, energy industry, environmental engineering (water – sewage – recycling) and medical technology applications.

Its design features a pressure port G1/2″ flush for paste-like and polluted media and a pressure port G1/2″ open port PVDF for aggressive media.

The DMK331 uses a ceramic pressure sensor so if the media is polluted, viscous or pasty, the sensor can be installed with the ceramic sensor face approx. 2mm from the front of the process connection, ensuring no clogging inside the pressure port.

Various supply options of 8-32Vdc, 10-28Vdc, 14-30V dc are available along with 4-20mA and 0-10Vdc supply options.  The DMK331 industrial aggressive media pressure sensor also comes with various mechanical and electrical connections to suit your application.

We are also able to customise the DMK331 industrial aggressive media pressure sensor to suit your exact requirements if necessary, whilst ensuring a minimal effect on price and availability.  Request pricing.
