Accessories for level sensors
Accessories for level sensors	Pressure compensation box	4262966
Accessories for level sensors	Pressure compensation box for rainwater utilisation systems (e.g. Wilo-RAIN3, Wilo-RainSystem AF 150) when the level sensor cable is longer than 20 m. The box enables a secure connection of the sensor cable and protects the capillary from deposits, dust and condensate by permanent protection (IP65). The electrical connection between the unit and box must be established with a cable without capillary for atmospheric pressure exchange. For optimum and economical use, attach the box as close as possible to the surface of the measuring medium.
