Transmisor de nivel sumergible

The PRIMEX® Submersible Level Transmitter (PSLT-IS) is specially designed for continuous level monitoring in the harshest environments including sanitary and stormwater lift stations having suspended solids. The instrument measures the hydrostatic pressure of the liquid above the sensor and outputs a 4-20mA signal proportional to the level.

The robust design of the PSLT-IS transmitter provides a reliable and low maintenance solution for critical level control applications where other level sensors easily foul.

Unit is suitable for operation in Class 1, Div 1, Groups C, D, T4 Hazardous Locations with optional Intrinsic Safety Barrier.
