Profile: Hydrolynx Systems, Inc. is a manufacturer of real time data telemetry systems. Our product line includes packaged systems, telemetry equipment, rain gauges, sensors, and field test equipment. Our 5050WD is the standard sensor used on the model 5081 packaged weather stations for measuring wind direction. The vane assembly, which responds to changes in wind direction, is attached to the shaft of a potentiometer. The potentiometer translates the wind direction into a 0-5 Vdc linear output, when a 5 Vdc reference voltage is applied across the potentiometer. Our model 5054TS is the standard ALERT rain gauge housing designed to attach to any ALERT station standpipe. It's design also allows for stand alone mounting with roof mount. It is used with the standard ALERT rain gauge sensor.
