CS800-L CLIMATRONICS
WIND SPEED AND DIRECTION SENSOR
1. GENERAL
The CS800-L sensors meet Environmental
Protection Agency (EPA) Prevention of
Significant Deterioration (PSD) requirements for
measuring wind speed and direction. The
sensors are mounted to a prewired crossarm,
which mounts to 3/4” IPS (1.05 inch O.D.)
vertical pipe stub. The 019ALU crossarm is
required to mount the CS800-L to the UT930
10m tower as shown in Figure 1, which allows
the lightning rod to be attached directly to the
mast.
Wind speed is sensed by a 3-cup anemometer
coupled to a light chopper that outputs a
frequency proportional to wind speed. Wind
direction is sensed by a wind vane coupled to a
precision low-torque potentiometer. Both
sensors use stainless steel precision ball
bearings for maximum life and low starting
thresholds.
Cable length is specified in feet, following the
(-L). Specify a 34 foot lead (CS800-L34) for
mounting the sensor to the UT930 10 m tower.
