Cup and Vane

The cup and wind vane anemometer is composed of:

Wind direction sensor with output in Ohms (wind vane).

• Light weight allows a long useful life to the potentiometer.
• Mechanical operation on a 360º angle without stop. Electrical angle 350º ± 3°, the threshold is of between 1,2 and 1,5 m/s.
• The PRV is a high quality wind vane with oiled rubbed bronze bearings and mounting hardware made of stainless steel.

Wind speed sensor with output in Hertzes (Cup).

• Light weight cup anemometer based on the Hall effect principle.
• Measuring range 0..60 m/s with a threshold of 0,5 m/s.
• Two impulses per rotation and 67 pulses in 30 m/s.
• PA2 is a high quality cup sensor including ceramic magnets and stainless steel bearings and assembly accessories.

4-20mA converter for direction and speed sensors.

• Changes output in Ohms for the wind vane and Hertzes for the cup sensor to 4-20mA output.
