3.5Precautions
1. Users are not allowed to disassemble by themselves, let alone touch the sensor core, so as
not to cause damage to the product.
2. Keep away from high-power interference equipment as much as possible to avoid
inaccurate measurement, such as inverters, motors, etc., when installing or disassembling the
transmitter, you must first disconnect the power supply. Water in the transmitter may cause
irreversible changes.
3. Prevent chemical reagents, oil, dust, etc. from directly invading the sensor, do not use it
for a long time under condensation and extreme temperature environments, and prevent thermal
shock
4. Calculation method
4.1Current output signal conversion calculation
Range 0~30m/s, 4~20mA output, when the output signal is 12mA, calculate the current wind
speed. The span of the wind speed range is 30m/s, expressed by a 16mA current signal,
30m/s/16mA=1.875m/s/mA, that is, the current change is 1mA and the wind speed change is
1.875m/s. Then the measured value can be calculated. The measured value is 12mA-4mA
=8mA.8mA*1.875m/s/mA=15m/s, then the current wind speed=15m/s.
4.2Voltage output signal conversion calculation
The range is 0~30m/s. Take 0-10V output as an example. When the output signal is 5V,
calculate the current wind speed. The span of the wind speed range is 30m/s, expressed by a 10V
voltage signal, 30m/s/10V=3m/s/V, that is, every 1V change in voltage corresponds to a wind
