Pressure gauge with LED display PTM82

stainless steel4-20 mAanalog output

The model PTM82 combines pressure and temperature measurement with a large, bright display. The digital contact gauge can still be easily read from a distance and therefore allows for a quick assessment of the process parameters. An analog output and two switch outputs widen the range of applications.  The  capacitive  measuring  principle in combination with a ceramic membrane is resistant to aggressive and abrasive media.  The process connection is made of high-quality stainless steel  1.4404 and is therefore suitable for almost all media.  All  wetted  components  are  food safe, making the unit ideal for use in beverage and process water applications.
