Digital wind speed sensor DHV 116
DHV116 is a rotating, optoelectronic sensor with frequency pulse output for measuring wind speed.
- Low-threshold starting speed
- Resistant to all weather conditions
- Compact dimensions
- Anodized aluminum and plastic
- Different output signal
- Type calibrated in wind tunnel
- Minimal maintenance
- Suitable for national met office
DHV116 is made of naturally anodized aluminum. High-quality sealed ball bearings are used in the rotating measuring system. A lightweight three-way assembly (Robinson's cross) rotates the stroboscope disk accross light beam generated by a long-life IR diode. Interruption of the beam causes a pulse output with its frequency, proportional to the wind speed. All electronic elements are protected against overvoltage by resistors and Zener diodes.
DHV116 is connected to the measuring system by 4-pin weatherproof connector, located at the bottom of the sensor. The sensor requires minimal maintenance. Even after years of use, when inexpensive and easily replaceable bearings are worn, measurements are almost unchanged. Bearings can be easily replaced if necessary. Additional mechanical loads, as icing, cannot damage the sensor.
