是一个四叶片螺旋桨。螺旋桨驱动可靠，非接触式传感器。4至20毫安电流输出指示信号。 该仪器安装在标准的1英寸的管径上。此款仪器通过了美国UL安全标准913测试

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.
