RECHNER Capacitive detection can make a major contribution to the trouble free functioning of your pellet heating system. RECHNER sensors control both the supply of the pellets to the industrial burner and the level of the storage unit. Different models are available in M18, M30 and M32 housings with metal or plastic bodies. Change of the material properties of the pellets, are no problem for RECHNER sensors. Once correctly adjusted, no readjusting of the switching distance is required. On request we can supply the sensors with a pre-adjusted switching distance: "READY TO GO". That means for you, unpack, install, connect = ready for use.
