screw-in transmitter LMP 331i
precision pressure transmitter with M12x1 connector and G1/2" pressure port

LMP 331i

stainless steel sensor
laboratory, environmental industry

The precision screw-in transmitter LMP 331i demonstrate the further development of our industrial pressure transmitters.

The signal processing of sensor signal is done by digital electronics with 16-bit analog digital converter. Consequently it is possible to conduct an active compensation and the transmitters with excellent maesurements and exeptionally attractive price to offer on the market.
