金属的风的速度传感器

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.2.Technical standards.
