GONIOANEMOMETER WITH FLAG ROTOR. Wind direction sensor
The gonioanemometer is a wind direction sensor.
It comprises a light alloy transducer containing the gonioanemometric system. This system consist of a potentiometer that provides resistance proportional to the direction the wind is blowing in. The "0°" (North) position reference of the potentiometer is shown by a red protrusion fitted to the body of the sensor. In the headet versions, a thermostat controls a heater that keeps the rotor moving effectively in case of freezing. The version range included transducers with "normalised" and with "direct" outputs. Sensors with "direct" output can be used, without the addition of signal conversion units, together with LASTEM acquisition systems. The sensor consists of the transducer (see "Versions"), vane flag rotor (code DNA017) and connectioon cable (see "Accessories").
