Cup Anemometer PVC Housing, Rotorof black painted Stainless Steel Type DWS-V-DBC05 • Anemometer with opto-electronic detection • Measuring range: 2 to 30 m/s • PNP and NPN open collector outputs in the same unit • Current source outputs • 10 to 28 VDC supply voltage • All inputs and outputs are protected against reverse polarity and transients • Dust sealing Product Description Ordering Key DWS-V-DBC05 DWS-V-DBC05 is a cup anemometerdesignedfor measuringairspeedina wide variety of applications, includingwindturbines, buildings,cranes,weather stations, green-houses, etc. Theproductcontainsboth PNP- and NPN open collec- tor outputs, in which a fixed current is switched propor- tionallytotheair speedat therateof10pulsesper m/s. The DWS-V-DBC05 is equipped with a specially designed protection mecha- nism, which protects the bearings and the electronic parts against dirt and humidity. The bodyofthesensoris made of black PVC, and the rotor is produced in stain- less steel.
