The SITRANS LH100 series pressure transmitter converts level-proportional hydrostatic pressure into a standardized 4 to 20 mA signal. Measuring just 23.4 millimeters in diameter, the sensor can be mounted in pipes with a 1 inch diameter, making it flexible for use in a wide range of applications. With mechanical protection IP 68, a submersible piezo-resistive sensor with ceramic diaphragm is designed for harsh environments.  The sensor is available with cable lengths ranging from three to a maximum of fifty meters in length. The Sitrans LH100 is also fitted with an integrated humidity filter, permitting simple installation without the need for a junction box.
