LH842 – Level Transmitter (Housing, Tank Connection, 316SS or Ceramic Sensor)
Sitron’s LH842 and LH842-Ceramic Hydrostatic Level Transmitters are used to measure the level of liquids in tanks, wells, and other containers. They work by measuring the pressure exerted by the liquid on the transmitter’s diaphragm, which is proportional to the liquid’s height. The LH842 models offer a great degree of mounting flexibility. They can be constructed with 316SS rigid rods or with long lengths of cable for depth measurement. Sitron offers either 316 S.S. piezoresistive silicone filled cells or thick film flush mounted ceramic cells.mounted (Rod or Polypropylene Vented Cable) on a threaded or flanged process connection with an electronic module within the housing enclosure, providing a Zero/Span adjustment. All of Sitron’s Hydrostatic Level Probes have a 4-20mA (2-wire) output signal, are fully temperature compensated within the stated range and are offered with surge protection. HART communication protocol is also available.
