SITRANS LH300 Pressure Transmitter

The SITRANS LH300 pressure transmitter is a submersible sensor equipped with protective caps made from polypropylene (PPE), stainless steel, and ethylene-tetrafluoroethylene (ETFE), designed for hydrostatic level measurement in fluids. This transmitter converts the liquid hydrostatic pressure—proportional to the liquid level—into a standard 4–20 mA signal. Featuring an IP68-rated stainless steel housing (Ø 30 mm) and a piezoresistive sensor with a ceramic diaphragm boasting 99.6% purity, it ensures versatility while remaining perfectly suitable for use in potable water systems. The pressure transmitter can accurately measure liquid levels in tanks, containers, trenches, and dams. Additionally, the SITRANS LH300 pressure transmitter is available across a wide range of measurement spans and is also offered in an explosion-proof version.
