Differential pressure transmitter PDM80-2

capacitiveanalogfor liquids

Model PDM80-2 features a large, bright display. The  transmitter can still be easily read from a distance and therefore allows a quick assessment of the process pressure. An analog output and 2 relays widen the range of applications.  The  electrical  connection  is done via an integrated terminal strip,  the PG11 cable gland provides IP65 dust and water protection.  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.
