The level controller board enables the level control of conductive liquids such as tap water, rain water or condensate. The measurement of the filling level in the container is effected through electrodes. These are mounted as contact surface on the container wall or stick electrodes are hanged up into the container.

You can get electrodes at B+B Thermo-Technik GmbH (article number SHOP ELEKT-PEND). Due to two independent stages the level controller enables the simultaneous control of the minimum and maximum liquid level and the activation of two different actuators, e.g. of a filler valve and a pump.

This model is a board without housing and without control panel. At B+B you can also get the suitable housing and the control panel – just send us your inquiry.
