Floating Ball Liquid Level Sensor

The floating ball liquid level transmitter is composed of magnetic floating ball, measuring conduit, signal unit, electronic unit, junction box and mounting parts. Generally, the specific gravity of the magnetic floating ball is less than 0.5, which can float above the liquid level and move up and down along the measuring conduit. The conduit is equipped with measuring elements, which can convert the measured liquid level signal into a resistance signal proportional to the change of liquid level under the action of external magnetism, And convert the electronic unit into 4 ~ 20mA or other standard signal output.
The liquid level sensor is a modular circuit, which has the advantages of acid resistance, moisture resistance, shock resistance and corrosion resistance. The circuit contains a constant current feedback circuit and an internal protection circuit, which can make the maximum output current no more than 28ma, so it can reliably protect the power supply and prevent the secondary instrument from being damaged.
