RNRG IceFree3 Heated Vane

The heated IceFree3 Vane is a proven and reliable solution for measuring wind direction in icing environments.

The IceFree3 Heated Vane’s head is directly connected to a 10K ohms conductive plastic potentiometer located in the main body. When a constant DC excitation voltage is applied to the potentiometer, it produces an analog voltage output directly proportional to the wind direction.

The sensor’s potentiometer linearity is within 1 percent of wind direction, ensuring precise measurements. The signal output is an analog DC voltage. The internal heater is powered by 24 VAC and allows for an operating temperature range of -40°C to 80°C (-40 °F to 176 °F). The optional 120/240 VAC to 24 VAC Transformer - IceFree3 Sensors is available to step down 120/240 VAC grid power.

The IceFree3 Heated Vane comes with an 8 m potted cable that can be extended to your desired length using Power Cable Kit - IceFree3 Sensor 3C, sold separately and available in 10 meter increments up to 90 meters.
