Our DE45 Differential pressure switch/transmitter is one of the very popular products . With the growing demand on functional safety in process instrumentation , our DE45 can now offer differential pressure for SIL 1 and SIL 2 applications.


The DE45 is a  multi-functional switching unit with an optional transmitter output. The optional output can be dampened, spread, inverted and transformed via a table function even if not linear! Suitable for measuring overpressure, underpressure and differential pressure in gaseus media, the DE45 can be used for various applications such as

  • Monitoring of roll filters, extraction systems, etc.
  • Draft measurement in chimneys
  • Flow and control pressure measurements
  • Surface coating systems


Apart from this, it can also be used to replace mechanical devices such as liquid column manometers to get a continuous signal.


Featuring  robust, resistant to overpressure and maintenance free design the DE45 is a one of our best-selling product.  With the updated product design, DE45 can now be used for differential pressure for SIL 1 and SIL 2 applications.
