Paddle flow switch DW-L


Other characteristics
reed switch, plastic


DW-L offers a cost-effective and yet flexible option to monitor the flow. The basic version of the device is completely made of plastic. Special variants allow combining it with metals for different applications. Proven functional principle – consequently improved The device works according to the paddle principle. The paddle is fixed on a bearing and protrudes into the flow. A magnet is attached to the opposite side. A second, external magnet repels the paddle magnet. This produces a restoring force. This force may be set by changing the distance between the magnets by means of a screw so that the switching point of the device can be adjusted easily and precisely. A reed switch fixed to the outside is actuated contact-free by means of the magnet on the pendulum. Plastic version – no corrosion Easy adjustment of the switching point by means of set screw No spring – always the same restoring force Low pressure loss Different versions, easy adaptation to different requirements Very favorable price
