Reed flow switch DP04 series

paddlefor liquidsstainless steel

The model DP04 flow switches operate according to the pad­dle principle. The flowing liquid pushes against the surface area of a paddle mounted at the end of a pivoting arm. The dynamic pressure against the plate deflects the arm. This motion causes a permanent magnet attached on the other end of the arm to switch an adjustable reed contact located outside the liquid being monitored. By moving the reed con­tact, different switching points can be set. Two repulsive magnets generate the restoring force. This results in better long-term stability and higher tolerance to pressure peaks. The possibility of installing the flowmeter directly in the pipe­line and shortening the paddle individually results in very flexi­ble areas of application. Typical applications The DP04 paddle flow switch is suitable for monitoring the switching point of low-viscosity liquids. Typical fields of application: – Cooling systems – Heating systems – Welding systems – Laser cooling systems Due to the paddle principle the device is really intensitive to dirt. paddle-type flow switch for liquids paddle can be cut individually for DN 20 to DN 200 with screw-in adaptor for T-fitting or direct installation into the pipe stabile switching points because of contra magnet technic plastic or stainless steel paddle max. pressure: PN 25, max. temperature: 110 °C couses ony slight pressure loss reed contact switching function depends only on flow, not on pressure and temperature of fluid switching ranges: 1,1...30 m³/h
