Intrinsically Safe Wind Monitor
The intrinsically safe Wind Monitor-IS is a high performance wind sensorapproved 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 fourblade propeller. The propeller drives a reliable, non-contacting transducer. Thewind direction sensor is a durable molded vane. Vane angle is sensed by aprecision, long-life potentiometer housed in a sealed chamber. Internalcircuitry converts signals for wind speed and wind direction into separate, 4 to20 mA current outputs. The instrument is constructed of UV stabilized plasticwith stainless steel and anodized aluminum fittings. The instrument installs onstandard 1 inch pipe.
*Tested in accordance with Safety Standard UL 913, Intrinsically SafeApparatus and Associated Apparatus for use in Class I, II, and III Division I,Hazardous (classified) locations. Must be properly installed with approvedIntrinsically Safe barrier.
