Pressure switch

Pressure Transmitterwith display and programmableswitching outputs
Type 540
The μP-regulated, programmable pressure transmitter type 540
has a robust industry design. The parameters are easily adjustable with two function keys in the configuration menue which
disposes of up to two programmable switching points.
All systems are equipped with a diagnostic function. The large 4
digit LED display assures a good accuracy of reading.
The pressure transmitter type 540 is based upon the Huba
Control developed thick film technology where the pressure
measuring cell is fully welded.

Pressure range
0 ... 60 – 600 bar+ Compact, rugged construction+ High over pressure+ Clearly readable display+ Sensitive operation keys
