FirstRate FST700-101 Submersible Liquid Level Transmitter Sensor, Range 0-2M, 4-20mA, 9-30V, IP68
The FirstRate FST700-101 is a submersible 4-20mA liquid level transmitter designed for continuous level monitoring in tanks, wells, and sumps. Featuring a 316L stainless steel probe and IP68 waterproof rating, it provides a robust, two-wire current loop output compatible with industrial PLCs, DCS, and data acquisition systems.
Features
- 4-20mA two-wire current loop output for robust industrial signal transmission.
- 0-2 meter H2O measurement range with ±0.5% FS accuracy.
- 316L stainless steel probe construction for corrosion resistance in harsh liquids.
- IP68 submersible rating and wide -40°C to +125°C storage temperature tolerance.
- Wide 9-30V DC supply voltage range for flexible system integration.

The FST700-101 operates on the hydrostatic pressure principle, where the sensed pressure is proportional to the height of the liquid column above the sensor’s diaphragm. This pressure is converted into a precise 4-20mA analog current signal, providing excellent noise immunity over long cable runs typical in industrial installations.
Its fully sealed 316L stainless steel housing and IP68 rating ensure reliable operation when fully submerged in a wide variety of liquids, including water, mild chemicals, and wastewater. The integrated 3-meter cable simplifies installation directly into process vessels.
