The intrinsically safe Wind Monitor-IS is a high performance wind sensor approved for use in hazardous areas.

The Wind Monitor-IS can safely be used in Class 1, Division 1, Group A, B, C, D hazardous areas.* The wind speed sensor is a four blade propeller. The propeller drives a reliable, non-contacting transducer. The wind direction sensor is a durable molded vane. Vane angle is sensed by a precision, long-life potentiometer housed in a sealed chamber. Internal circuitry converts signals for wind speed and wind direction into separate, 4 to 20 mA current outputs. The instrument is constructed of UV stabilized plastic with stainless steel and anodized aluminum fittings. The instrument installs on standard 1 inch pipe.

* Tested in accordance with Safety Standard UL 913, Intrinsically Safe Apparatus and Associated Apparatus for use in Class I, II, and III Division I, Hazardous ( classified) locations. Must be properly installed with approved Intrinsically Safe barrier.
