Proximity Sensors

Level sensors based on reed relay technology from Celduc

The advantages of level sensors is that they have only one moving part. The reed relay is activated by the magnetic field. This means that no mechanical contact is necessary. Ultimate water resistance is achieved, since the reed relay switching part is completely separate from the liquid. The benefits of the level sensors is that it provides a very safe operation, superior repetitive accuracy, precision and minimal maintenance.

Working principle
A float, which is equipped with either one or several magnets, moves with the liquid and activates in the indicated level thanks to a magnetic field. A hermetically separated reed switch is activated when the float reaches the switching position.
