Applications of level transmitter

·liquid level measurement for tank

Introduction of level transmitter

LT60H level transmitter made by ORR’s own pressure sensor core as sensor sensitive element. Level transmitter can be transferred liquid or gas pressure into the various standard analog output signal 4~20mA. 

The water-proof cable connects with housing sealed, with vented tube putting in, the level transmitter could be used in the water or liquid in a long time. Integrated construction and standard output signal could provide easy operation and good automatic control. With 2-wire working, compact size, light weight and easy installation and operation, LT60H level transmitter is widely used for industry field instead of normal 2-wire 4~20mADC analog output transmitter.
