Devices for Level Regulation
Float Switch for Determining Liquid Levels
Connection Diagram
This float switch is used for monitoring the level of liquid and for protecting heaters, pumps etc. from drying out. The float switch (Part No. 56672/ 79) with switching point determines the level of liquid in the tank. Float switches 56675 and 56676 allow the regulation of two different liquid levels in a tank. The upper and lower switching points are regulated with change-over switches. The magnet which is built into the floating contact influences the reed contact which is fixed in the float shaft. If the float sinks to the lower stop then a contact opens or/and closes. On floating switches with two contacts, the switching is done when the float comes close to the upper or lower stop. The floating switches are equipped with an adjustable height mounting clamp. For types with two switching points, 2 reed contacts are built into the units. The switching distance between the contacts is defined by the user in the order and cannot be changed afterwards. The standard cables are 1.6 m long.
