Mechatronic flow sensor
The flow sensor works to the principle of spring-supported piston: The piston located in the valve seat in the housing is lifted by the flowing medium against the spring resistance. The piston position is detected in a binary way via an inductive sensor or in an analogue way via a sensor with GMR cell. The spring resistance leads to reliable reset of the piston to its initial position with decreasing flow. This ensures position-independent installation of the flow sensor preventing backflow. The switch points can be individually set and fixed via a setting screw. The robust mechanical design ensures use at high pressures and in harsh environments. The units are maintenance-free.
