LE2161 Wind Direction Sensor is a highly accurate and reliable sensor for the measurement of wind direction in wind farm. With anti-lightning surge, anti-static protection, safety performance improved.According to their output signal is divided intothe number type (Gray encoder output) and analog-type (0 20mA / 4 20mA analog signal output) of two. 1.Performance profileThe sensor is designed compactly, the winddirection use enhanced carbon-fiber and easily maintain. it has a heating system in the wind indicator that can prevent from freezing, it can work in the severe environment.Using fault-tolerant design, pick the wrong line of the sensor is not damaged;With the over-current over-voltage protection,it can be 18 30V wide voltage range of normal working.The wind measuring range of 0 360 °, accuracy up to ± 1.5 °.The wind measurements to start with low wind speed: 0.5m / s.2, Technical standards.Digital signal type Analog signal typeSensor Power Supply24V±6V DC24V±6V DCHeating device Power Supply24V±6V AC/DC24V±6V AC/DCHeating device power20W max20W maxOutputGray code output (4, 7-bit)0 20mA current / 4 20mA currRange0 360°0 360°Accuracy±1.5°±1.5°Operating temperature (normal type)-30 70-30 70Operatingtemperature (low temperature type)-40 80-40 80Maximum relative humidity40°95%, non-condensing40°95%, non-condensingProtection LevelIP55IP55Surge protection (lightning)6KV/5KA6KV/5KAESD Protection15KV15KV
