Heavy Duty Wind Monitor-HD-Alpine 05108-45

Make: RM Young              Model:  05108-45
✅ The Wind Monitor-HD Alpine combines the features of the Heavy Duty unit along with the ice-resistant coating of our popular Alpine Wind Monitor.
✅ Measurand : Wind Speed , Wind Direction.
✅ Principle Used : 18 cm diameter 4-blade helicoid propeller, Balanced vane, 38 cm (15 in) turning radius.
✅ Signal Output : Wind speed: magnetically induced AC voltage, 3 pulses per revolution, 1 rev = 50 cm air passage. Wind direction: Analog DC voltage from conductive plastic potentiometer-resistance 10KΩ, 0.25% linearity, life expectancy 50 million revolutions.

The YOUNG Model 05108-45 Heavy Duty Wind Monitor HD-Alpine measures horizontal wind speed and direction.  This sensor includes ceramic bearings, ¼ inch diameter propeller shaft and high pitch propeller as found in Model 05108.  To improve performance in in high elevation Alpine environments this model has the additional features of an all-black design for thermal warming from sun exposure and a specially formulated, ice resistant coating applied to all external surfaces.  The direct output for wind speed is an AC sine wave and direction is a precision potentiometer.  This sensor mounts on a standard 1-inch IPS pipe.  A mounting orientation ring is included.

A separate Surge Protection Assembly, Model 19120, is available that doubles as both a junction box for cable termination and additional electrical transient surge protection.  Separate signal conditioning devices are available to convert the sensor signals to 0-5 V (Model 05608C) or 4-20 mA (Model 05638C).  All three of these devices are enclosed in weatherproof enclosures and come with mounting hardware (Model 19120 is not typically used in conjunction with either Model 05603C or 05631C).
