NovaLynx - Model 200-WS-23 - Current Loop Wind Sensor
The 200-WS-23 Current Loop Wind Sensor monitors wind speed and direction. The electronics converts the raw signals from the wind sensors to proportional 4 to 20 mA current loop values for use by process control or monitoring systems. It acts like a variable resistance that draws 4-20 mA when powered with 8 to 30 Vdc. No external power is required because the encoding electronics for wind speed and for wind direction are isolated and powered from their respective 2-wire current loops.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.
