R.M. Young Wind Sentry
1. Introduction
The 03001 Wind Sentry Set is used to measure horizontal wind speed and
direction.
Wind speed is measured with a three cup anemometer. Rotation of the cup
wheel produces an AC sine wave voltage with frequency proportional to wind
speed.
Vane position is transmitted by a 10K ohm potentiometer. With a precision
excitation voltage applied, the output voltage is proportional to wind direction.
The 03101 Anemometer and 03301 Vane can be ordered as separate sensors,
which are also covered in this manual. The R.M. Young Instruction Manual
includes additional information on the operating principles, installation and
maintenance of the sensor.
Lead length for the Wind Sentry is specified when the sensor is ordered.
Table 1-1 gives the recommended lead length for mounting the sensor at the
top of the tripod/tower with a 019ALU or CM200 series crossarm.
