Liquid level sensor HT-ZPC5

They are used wherever it is necessary to control and regulate the level of liquids (e.g. water, oil, etc.). Resistant to acids and alkalis. The sensor has a float equipped with a magnet, which moves vertically along the guide tube under the influence of the buoyancy force of the liquid, causing the reed switch to short or open. They are usually mounted in the lid of the tank, so they can be used to control the upper liquid level.

Technical data

Note

The design of the sensor does not allow the connection of 230V mains voltage, so it is recommended to use AFR1 relay with built-in 8VAC safe voltage source to power the sensors.

Principle of operation

The sensors have a magnet fixed in the float, which, when raised, causes the contact of the reed switch, located in the body of the tube, to short or open. The sensors can operate as NO - normally open.

high state: on low state: off

Example of application

Maintaining the level of liquid in the tank at any levels, high and low, using the relay AFR1 available on our other auction. Relay AFR1 Allows both the actuation of an actuator device (such as a pump, solenoid valve) and the supply of up to two sensors with low control voltage.
