Principle Of Operation:


The sensor used for measurement is an RTD ( PT 1000). Here the resistance of the element varies with temperature (increases with temperature), approximately 3.9 ohms/degree Celsius. The weather shield Is provided to avoid direct heating of the sensor by sun’s radiation and to protect it from rain and snow.

Specifications :

Wind speed Sensor	3 Cup Anemometer.
Sensing	3 cup assembly mounted on friction free shaft and coupled to a chopper.
Starting threshold	0.3 meters/sec.
Range	0 to 65 meters/sec.
Distance constant	2.5 Meters
Output	TTL pulses output proportional to wind speed Built in line driver to drive long cable > 50 ohms loop resistance.
Accuracy	Better than 0.5 m/s up to 10 m/s + 2% FSD
Diameter of cup	50 mm.
Diameter of cup assembly	165 mm.
Construction of sensor body	Brass housing and stainless steel shaft

Principle Of Operation:


Anemometer is a fast response, low threshold opto electronic anemometer. When rotated by wind, a chopper on the anemometer shaft interrupts an infra red light source , generating pulses from a photo transistor. The signal is amplified and fed through a line driver . The frequency is proportional to wind speed. The anemometer is provided with a 3 pin connector for easy replacement and comes with 10 meters of shielded cable.


For operation at low temperature the sensor can be supplied with a built in heater The Anemometer can be supplied with a 20W 24 V DC built in heater for operation at low temperatures.
