Pressure

Hydrostatic Pressure Transmitter

The Lh series of hydrostatic pressure transmitters and level is designed for measuring the pressure of liquids in a variety of industrial processes. Each model offers excellent stability, repeatability and accuracy with temperature and atmospheric compensation. Output options include 4-20mA, 1-5volts, 1-10volts and HART communication protocol.
