Detailed Product Description
LE2152 Metal Wind Speed Sensor is a highly accurate and reliable sensor for the measurement of wind speed in wind farm.
With anti-lightning surge, anti-static protection, safety performance improved.
According to their output signal is divided into numeric (0 ~ 20V digital pulse signal output) and analog-type (0 ~ 20mA / 4 ~ 20mA current signal output)
1.Performance profile.
The sensor is designed compactly, the metal star-shaped wind cup use stainless steel and easily maintain which be used in the severe environment. It has a heating system inside that can prevent bearing and external rotating parts from freezing in winter to ensure the sensors work in low temperature condition.
The sensor fault-tolerant design, pick the wrong line of the sensor is not damaged; with the over-current over-voltage protection, can be 18 ~ 30V wide voltage range work.
The sensor data collected with high precision and reliability.
Wind speed measurement range: 0.5 ~ 50m / s; start with low wind speed: 0.5m / s.
