Advantages Of Liquid Level Sensor

- Jun 04, 2019-

Floating ball liquid level transmitter is composed of magnetic float ball, measuring tube, signal unit, electronic unit, junction box and installation parts. Generally, the specific gravity of magnetic float ball is less than 0.5. It can float above the liquid level and move up and down along the measuring tube. The tube is equipped with measuring elements. It can convert the measured liquid level signal into resistance signal proportional to the change of liquid level under the action of external magnetic field, and also convert the electronic signal into resistance signal proportional to the change of liquid level. The unit is converted to 4-20 mA or other standard signal output.

The liquid level sensor is a modular circuit, which has the advantages of acid resistance, moisture proof, shock proof and corrosion protection. The circuit contains constant current feedback circuit and internal protection circuit, which can make the maximum output current not exceed 28mA. Therefore, the power supply can be reliably protected and the secondary instrument can not be damaged.
