LHT840 – Level and Temperature Transmitter (Sensor and Cable)
Sitron’s LHT840 combines process Temperature monitoring and a Hydrostatic Level monitoring into one transmitter. This unit can be used to measure both the temperature and the level of liquids in tanks, wells, and other containers.
The LHT840 is offered with a great degree of mounting flexibility and can be made in a wide variety insertion lengths and pressure ranges. The LHT840 models can also be ordered as the LHT842 with an electronics module within the enclosure, providing a Zero/Span adjustment. They can be constructed with 316SS rigid rods or with long lengths of cable for depth measurement. 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.
Hydrostatic level measurement is commonly used in various industries, including food, water/wastewater, and chemical processing, to name a few.
