MPM4700 level transmitter is the full stainless steel construction and full-sealed submersible intelligent level transmitter with high accuracy. It uses highly reliable and stable pressure sensor, intelligent processing circuit, precise digital temperature compensation and linearity correction technics for production. The water-proof cable connects with housing sealed, with vented tube putting in, the 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, it is widely used for industry field instead of normal 2-wire 4mA~20mA DC analog output transmitter.


  • 4mA~20mA DC 2-wire current output;
  • Digital temperature compensation and linearity correction;
  • RS485 communication interface(Custom protocol) or HART® communication protocol(optional);
  • Netting application;
  • Full stainless steel construction, compact size, light weight;
