Flow switch Henke-Sass DW-LE

Henke-Sass Series DW

• 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
• Thanks to the magnet, there are no signs of fatigue like a feather
