HT400-2SL liquid level sensor
103.25zł Tax excluded
They are used wherever it is necessary to control and regulate the level of liquids (such as water, oil, etc.). 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 circuit or open. They are usually mounted in the bottom or lid of the tank, so they can be used to control the lower or upper level of the liquid. By changing the position of the float, the function of the reed switch is changed from short-circuit to open.

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 level of liquid in a tank at any level, 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.
Maintain the liquid level in the tank at any level, high or low, using the AFR1 relay.
