Description

The Wind Speed Sensor – Model 5711-00 has proven itself to be rugged, reliable, and highly accurate in wind tunnel and mountain-top tests and in thousands of household and institutional installations.

The Wind Speed Sensor’s low moment of inertia and unique bearings permit very rapid response to gusts and lulls. The Wind Speed Sensor’s black polycarbonate cups (virtually shatter-proof) have thermal properties which let it resist and shed ice far more effectively than metal assemblies. Because of the Wind Speed Sensor’s output linearity, this sensor is ideal for use with various data collection systems used in meteorological monitoring.

The Wind Speed Sensors feature a 3-cup anemometer assembly. Cup wheel rotation produces a sine wave signal with frequency directly proportional to wind speed. This AC signal is induced in a coil by a two pole circular magnet mounted on the Wind Speed Sensor’s cup wheel shaft. Two full cycles are produced for each rotation of the Wind Speed Sensor.

Installation of the Wind Speed Sensor – Model 5711-00 is easily accomplished with the optional Mounting Arm & Hardware available for mounting to a tower or standpipe mast. The Wind Speed Sensor includes 25 ft (7.6 m) of cable.

NOTE: A Pre-Divide Signal Conditioning Board – Model 5711-02 may be required if the Wind Speed Sensor is attached to a data monitor or transmitter other than a High Sierra Electronic instrument.
