The material of the liquid insertion part is SUS304/316L, which has good corrosion resistance.

The LST series liquid level sensor and transmitter are mainly composed of a guide rod with a built-in reed switch and a floating ball with magnetic steel. When the floating ball with magnetic steel moves with the liquid level, the reed switch inside the guide rod is closed in sequence by magnetic force. The sensor outputs an analog resistance value signal that changes with the liquid level. The resistance value signal is processed by R/I converter and other circuits to output a 4-20mA or 0-5VDC analog signal, realizing liquid level measurement, display and long-distance signal transmission.
