Liquid level sensor HT19 1/2" 

They are used wherever it is necessary to control and regulate the level of a liquid (e.g. water, oil, etc.). The sensor has a float equipped with a magnet, which rises under the influence of the buoyancy force of the liquid, causing the reed switch located in the tube to short circuit or open. They are usually mounted in the wall of the tank, so they can be used to control the lower or upper level of the liquid. They are made of stainless steel and can be used in a wide range of temperatures.

Note
The design of the sensor does not allow the connection of 230V mains voltage, so it is recommended to use the relay AFR1 with a built-in safe voltage source of 8VAC to power the sensors.
Principle of operation
The sensors have a magnet fixed in the float, which, by rising, causes the contact of the reed switch located in the body of the tube to short or open. The sensors can operate as NC - normally closed or NO - normally open. Changing the mode of operation is achieved by rotating the float by 180°.

Example of application
Maintaining the liquid level in the tank at any levels, high and low using the AFR1 relay available in our store. 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.
