Sitron's Hydrostatic Level Probes have identical features as the Pressure Sensors with one main difference: They are submersible. Hydrostatic Level Probes are specifically designed for depth/level measurements in groundwater, deep wells, water towers, rivers, sewage treatment plants and other similar applications. The Hydrostatic Level Probes are fully encapsulated and are housed in a weatherproof cylindrical enclosure. Offering a great degree of flexibility, they can be constructed with 316S.S. rigid rods or with special cables for depth measurements.

These probes can be made with either 316 S.S. piezoresistive or ceramic cells. Their compact design enables the probes to work within pipe diameters as little as 3/4”. The 842 models are available with an electronic module within the enclosure providing a Zero/Span adjustment. All of Sitron's Hydrostatic Level Probes have a 4-20mA (2 wire) output signal and are fully temperature compensated. Like all of Sitron's products, the Hydrostatic Measurement Level Probes can be made in a wide variety of process connections.

Hydrostatic Level Probes utilize the same pressure sensing technology as the pressure sensors; as hydrostatic pressure increases with the height of the water column a displaced electrical charge accumulates on the opposing surface of the cell (316 S.S. piezoresistive or ceramic). This generates an output signal, which is converted to a standardized 4-20-mA (2 wire) signal that is directly proportional to the pressure applied.
