Pressure transmitter

Relative and differential
pressure transmitter
Type 652
Type 652 pressure transmitters are ideally suited to the continuous monitoring of liquid or level, (especially in heatingtechnology).
Their especially rugged construction allows a single port overpressure of up to 20 bar, depending upon pressure range.

Pressure range
0 ... 50 – 1000 mbar

+ High overpressure safety margin 10/20 bar on P1+ 3 standardised output signals for direct
Processing in control / monitoring systems+ Functionally simple, rugged mechanics with highoperating reliability+ Attractive price / performance ratio+ Also for slightly aggressive liquids and gases
