User's manual
The YOUNG Model 05501LM Wind Monitor-IS measures horizontal wind speed and direction and can safely be used in Class 1, Division 1, Group A,B,C,D hazardous areas.* A four-blade helicoid propeller, used to measure wind speed, generates an AC sine wave signal upon rotation. Wind direction is determined by a vane attached to a precision potentiometer inside an internal housing. Internal circuitry converts the signals into isolated, 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 IPS pipe. A mounting orientation ring is included that engages with the base of the sensor to retain orientation when the sensor is removed for maintenance. Terminations are made in a junction box at the base of the sensor by small clamp-style connectors (no special connectors are required).
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.
