Wind speed and direction or just wind speed sensors with various bracket accessories. |
Product Summary |
|
The Wind Sensor System comprises two sensors, a wind speed only sensor and a combined wind speed and direction sensor. Both are manufactured in clear anodised (HT30) aluminium alloy. The Wind Speed section of either sensor consists of a low-inertia ABS cup assembly for fast response mounted on a dual ballrace-supported stainless steel shaft. The use of a Bremag 10 magnet operating a long life reed switch produces one bounce-free pulse per revolution of the rotor. The Wind Direction component of the dual sensor consists of a dynamically balanced wind vane operating a triple ballrace supported shaft and micro-torque potentiometer with a small deadband of 3 degrees, usually at North, the Potentiometer is usually connected as a potential divider. With the above designs, most modern loggers can be connected to these sensors with little or no interfacing. An additional benefit is the zero power requirement. Various possibilities exist for mounting either units and a machined 8mm stainless steel stud is supplied for this purpose. However, two mounting systems are recommended; the full mast kit or the bracket kit, and both sensor units are available with each of the mounting options. For OEM use, special mountings could be made to suit if required, dependent on demand. Please contact our Technical Department to discuss your exact requirements. |
