DHV 116 DIGITAL WIND SPEED SENSOR
Wind speed sensor DHV 116 is equipped with a 3-cup Robinson's cross as a sensing element. Both sensors are made from stainless steel and anodized aluminium.
DHV116 is a digital sensor which transformes the rotation of the Robinson's cross into a series of voltage impulses by means of stroboscope and optoelectronic elements. It is used primarily for wind-measurements to ensure the safe operation of the cranes, cable cars, etc. Resistance of connecting wires does not affect the accuracy of measurements, so the sensor can be located several kilometers from the wind speed measuring system. DHV 116 was calibrated as a sensor-type and does not require individual calibration. DHV 116 is fully compatible with sensors DHV 39 and DHV 76 with slightly higher starting speed.
All mechanical and electrical parts are tied to the base-plate, where also signal connector and mounting hole are to be found. Sensors can be dismounted by unscrewing the base-plate thus separating the sensing elements from the vertical axis.
To prevent icing, as an option, sensors can be anodized in black. When icing is very likely to occur, black anodized sensors should be radiated from outside with an infrared light beam.
