Pressure Transmitter

The SITRANS LH100 series pressure transmitter is a well probe and converts the level-proportional hydrostatic pressure into a standardized signal of 4 to 20 mA. It measures the level in basins, tanks, canals and dams. The SITRANS LH100 is available for different measuring ranges and optionally with explosion protection. The transmitter has a stainless steel housing and a piezoresistive sensor with a ceramic diaphragm.
