Magnetic Paddle Flow Sensor/Switch for Easy On/Off Control

Transcription

1 Magnetic Paddle Flow Sensor/Switch for Easy On/Off Control INLINE Quarter-Turn ON/OFF Control System for Monitoring and Switching Mechanical adjustment of set point No contact to Fluid thanks to INLINE Quarterturn Technique This mechanical single paddle Sensor/Switch is specially designed for monitoring minimum/maximum values of flow. The switching point can be set by turning a spring screw. The switching is done by a moving magnet and a reed contact. The connection to the process in the piping is done with the easy to connect quarter-turn technique of the INLINE fittings.

3 S BRASS, INLINE Quarter-Turn ON/OFF Control System for Monitoring and Switching in Combination with SE unit No Leakage due to Single Paddle inside the fitting (INLINE Quarter-Turn Technology) Contact Free Switching of Reed Contact by Magnetic Transmission The fitting S has the single paddle to detect the flow built in. This leads to a very leak proof construction, which we call the INLINE Quarter-Turn Technology. The switching point is transmitted contact free by a magnetic field. The detecting unit SE can be snapped-on or removed without opening the pipe of the process. The switching point can be set on the unit SE.
