Calculation Method
Wind Speed Sensor
1 Calculation current mode outputs the converted signal
Range 0 ~ 30m / s, 4 ~ 20mA output when the output signal is 12mA, the current wind speed is calculated. Winds range span of 30m / s, to express 16mA current signal, 30m / s / 16mA = 1.875m / s / mA, i.e., the current wind speed variations 1mA 1.875m / s. So the measured values can be measured Calcd 12mA-4mA = 8mA.8mA * 1.875m / s / mA = 15m / s, the current wind speed = 15m / s.
2 voltage-converts the output signal calculation
Range 0 ~ 30m / s, 0-10V output to an example, when the output signal of 5V, the current wind speed is calculated. Winds range span of 30m / s, with a 10V voltage signal expression, 30m / s / 10V = 3m / s / V, i.e., the voltagecorresponding to the wind speed change by 1V 3m / s. Measurement 5V-0V = 5V. 5V * 3 / m / s / V = 15m / s. The current wind speed is 15m / s.
