Scale
easy
Scales a raw 4-20 mA sensor signal to a 0-100 °C engineering unit value.
What it teaches
Map a sensor's 4-20 mA signal into 0-100 °C. The everyday analog conditioning pattern — when the sensor reads 4, the output is 0; when it reads 20, the output is 100; everything between scales linearly.
Parameters
| Tag | Direction | Type | Default | Description |
|---|---|---|---|---|
| In_Raw | Input | REAL | 0 | Raw analog input signal in mA |
| Out_Scaled | Output | REAL | 0 | Scaled output value in degrees Celsius |
Required behavior
- Out_Scaled is 0.0 when In_Raw is 4.0.
- Out_Scaled is 100.0 when In_Raw is 20.0.
- Out_Scaled interpolates linearly for In_Raw values between 4.0 and 20.0.
- Out_Scaled extrapolates linearly for In_Raw values outside the 4.0 to 20.0 range.
