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

● 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 high operating reliability
● Attractive price / performance ratio
● Also for slightly aggressive liquids and gases
