  For example, the range is 0~30m/s, the analog output is 0~5V DC0-5Vvoltage signal, wind speed and DC0-5Vvoltage The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is wind speed range upper limit, A1 is the lower limit of the range, B2 is DC0-5Vvoltage output range upper limit, B1 is the lower limit, X is the currently read wind speed value, and C is the calculated DC0-5Vvoltage value. The list of commonly used values is as follows:
DC0-5Vvoltage(V) wind speedValue (m/s) Calculation Process
0 0.0 (30-0)*(0-0)÷(5-0)+0
1 6.0 (30-0)*(1-0)÷(5-0)+0
2 12.0 (30-0)*(2-0)÷(5-0)+0
3 18.0 (30-0)*(3-0)÷(5-0)+0
4 24.0 (30-0)*(4-0)÷(5-0)+0
5 30.0 (30-0)*(5-0)÷(5-0)+0
    As shown in the above formula, when measuring 2.5V, current DC0-5Vvoltage is 15m/s。
  For example, the range is 0~30m/s, the analog output is 0~10V DC0-10Vvoltage signal, wind speed and DC0-10Vvoltage The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is wind speed range upper limit, A1 is the lower limit of the range, B2 is DC0-10Vvoltage output range upper limit, B1 is the lower limit, X is the currently read wind speed value, and C is the calculated DC0-10Vvoltage value. The list of commonly used values is as follows:
DC0-10Vvoltage(V) wind speedValue (m/s) Calculation Process
0 0.0 (30-0)*(0-0)÷(10-0)+0
1 3.0 (30-0)*(1-0)÷(10-0)+0
2 6.0 (30-0)*(2-0)÷(10-0)+0
3 9.0 (30-0)*(3-0)÷(10-0)+0
4 12.0 (30-0)*(4-0)÷(10-0)+0
5 15.0 (30-0)*(5-0)÷(10-0)+0
6 18.0 (30-0)*(6-0)÷(10-0)+0
7 21.0 (30-0)*(7-0)÷(10-0)+0
8 24.0 (30-0)*(8-0)÷(10-0)+0
9 27.0 (30-0)*(9-0)÷(10-0)+0
10 30.0 (30-0)*(10-0)÷(10-0)+0
    As shown in the above formula, when measuring 5V, current DC0-10Vvoltage is 15m/s。
