4-20 mA wind direction sensor 3S-WD-I

analogIP67IP54

Product overview
The Wind Direction Sensor 3S-WD-I measures horizontal wind direction in degrees (0–359°). It consists of a vane and a sensor body and provides an industry-standard analog output compatible with dataloggers, gateways and PLCs. The unit is supplied with mounting fittings and a 3 m UV- and weather-resistant cable.

Applications & installation
Designed for meteorological and industrial monitoring, the sensor is suitable for solar farms, weather stations, building sites and other installations requiring reliable wind direction data. It can be mounted on a mast or fixed to ground structures; the 4-20 mA output allows direct connection to common industrial data acquisition systems.

Compliance & maintenance
The product meets IEC 61724-1:2021 requirements. Routine visual checks and periodic cleaning of the vane are recommended for long-term accuracy. Optional IP67 variant is available for environments with high ingress risk.
