Climatronics WindMark III
Features
- low threshold
- low cost
- low power
- lightweight
- optional external heaters
Climatronics WindMark III combines accuracy and reliability with
low cost. They are well suited for general wind monitoring applications.
Windspeed is sensed by a three-cup anemometer and converted to an
electrical signal by a solid-state photo chopper. A counter balanced
wind vane coupled to a precision, low torque potentiometer senses
wind direction. The sensors use stainless steel precision ball bearings
for maximum life and low threshold. Traceability to NIST is available
as an option. The sensors and their crossarm are an integral unit.
The WindMark III can be provided with a 4..20 mA current loop output.
