The pressure transmitter SITRANS LH300 is a submersible sensor for hydrostatic level measurement with protective caps made of PPE, stainless steel and ETFE. The transmitter converts the level-proportional hydrostatic pressure into a standardized 4 to 20 mA signal. The transmitter consists of a stainless steel housing (Ø 30 mm) with mechanical protection IP68 and the piezo-resistive sensor with a ceramic diaphragm made of 99,6 % purity ceramic ensures versatile use, also good in drinking water systems. The pressure transmitter measures liquid levels in tanks, containers, channels and dams. SITRANS LH300 pressure transmitters are available for various measuring ranges and with explosion protection as an option.


  • Easy installation and use due to compact design and corrosion-resistant material
  • Safe application due to venting pipe in connection cable to prevent condensate formation
  • Long service life due to the protection of the measuring diaphragm against external influences by a protective cap

Standard measuring set: Transmitter, cable hanger, junction box
