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.
