NovaLynx - Model 200-WS-23 -Current Loop Wind Sensor

Two versions are offered. The 200-WS-23 measures both wind speed and direction, while the 200-WS-23S measures wind speed only. Both systems consist of two subassemblies, a wind sensor and a signal conditioning electronics package in a NEMA housing. Although it has only one PC board, it contains two completely independent circuits, one for wind speed and one for wind direction.

The wind sensor includes a three cup anemometer and wind vane. The sensor is ruggedly constructed of UV resistant ABS plastic and anodized aluminum parts, and includes 40` of cable. Additional cable lengths can be supplied. The electronics package is supplied in a gasketed wall mount NEMA enclosure.
