1. temperature and current computing relationship

  For example, the range is -30~80℃, the analog output is 4~20mA current signal, temperature and current The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is temperature range upper limit, A1 is the lower limit of the range, B2 is current output range upper limit, B1 is the lower limit, X is the currently read temperature value, and C is the calculated current value. The list of commonly used values is as follows:
current(mA)temperatureValue (℃) Calculation Process
4-30(80-(-30))*(4-4)÷(20-4)+-30
5-23.125(80-(-30))*(5-4)÷(20-4)+-30
6-16.25(80-(-30))*(6-4)÷(20-4)+-30
7-9.375(80-(-30))*(7-4)÷(20-4)+-30
8-2.5(80-(-30))*(8-4)÷(20-4)+-30
94.375(80-(-30))*(9-4)÷(20-4)+-30
1011.25(80-(-30))*(10-4)÷(20-4)+-30
1118.125(80-(-30))*(11-4)÷(20-4)+-30
1225(80-(-30))*(12-4)÷(20-4)+-30
1331.875(80-(-30))*(13-4)÷(20-4)+-30
1438.75(80-(-30))*(14-4)÷(20-4)+-30
1545.625(80-(-30))*(15-4)÷(20-4)+-30
1652.5(80-(-30))*(16-4)÷(20-4)+-30
1759.375(80-(-30))*(17-4)÷(20-4)+-30
1866.25(80-(-30))*(18-4)÷(20-4)+-30
1973.125(80-(-30))*(19-4)÷(20-4)+-30
2080(80-(-30))*(20-4)÷(20-4)+-30
    As shown in the above formula, when measuring 8mA, current current is 31.5℃。

2. humidity and current computing relationship

  For example, the range is 0~100%RH, the analog output is 4~20mA current signal, humidity and current The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is humidity range upper limit, A1 is the lower limit of the range, B2 is current output range upper limit, B1 is the lower limit, X is the currently read humidity value, and C is the calculated current value. The list of commonly used values is as follows:
current(mA)humidityValue (%RH) Calculation Process
40.0(100-0)*(4-4)÷(20-4)+0
56.3(100-0)*(5-4)÷(20-4)+0
612.5(100-0)*(6-4)÷(20-4)+0
718.8(100-0)*(7-4)÷(20-4)+0
825.0(100-0)*(8-4)÷(20-4)+0
931.3(100-0)*(9-4)÷(20-4)+0
1037.5(100-0)*(10-4)÷(20-4)+0
1143.8(100-0)*(11-4)÷(20-4)+0
1250.0(100-0)*(12-4)÷(20-4)+0
1356.3(100-0)*(13-4)÷(20-4)+0
1462.5(100-0)*(14-4)÷(20-4)+0
1568.8(100-0)*(15-4)÷(20-4)+0
1675.0(100-0)*(16-4)÷(20-4)+0
1781.3(100-0)*(17-4)÷(20-4)+0
1887.5(100-0)*(18-4)÷(20-4)+0
1993.8(100-0)*(19-4)÷(20-4)+0
20100.0(100-0)*(20-4)÷(20-4)+0
    As shown in the above formula, when measuring 8mA, current current is 29%RH。
