Paddle flow switch DP05

for liquidsstainless steelbrass

The flow switches model DP05 operates according to the paddle-bellows principle. The flowing liquid pushes against the surface area of a paddle mounted at the end of a pivoting arm. The arm is deflected against the force of a spring. This deflection is mechanically transmitted to an adjustable contact unit. A bellow systems seals the mechanism hermetically from the liquid. In case of malfunction, the spring returns the paddle plate to the zero position (no flow), which causes the system to signal a fault automatically. Typical applications The DP05 paddle-bellows flow switch is suitable for monitoring thin and low-viscosity liquids in average to large flow volumes, eg. for industrial water circuits because they are relatively insensitive to dirty/contaminated fluids. For nominal pipe sizes over DN 50, installation with a special intermediate mounting flange yields a price/performance ratio of exceptional economy. for pipe diameters from 3/8" to DN 600 insensitive against dirty media and electromagnetic fields medium hermetically sealed from switching element by means of a stainless steel bellows materials: brass, stainless steel or PVC max. pressure: 16 bar, max. temperature: 100 °C with 1 or 2 highly rated microswitches (250 V, 10 A) switching ranges: 1-5 l/min ... 1250-4500 m³/h water
