User Guide
This measurement to current converter tool will convert any linear input measurement reading into the ideal current output signal over a linear range of 0 to 20 milliamps, and display a 0-20mA conversion scale for the chosen measurement range.
Formula
This tool uses the following formula to calculate the output over a 0-20mA scale from a specified measurement input reading and range:
Linear mA out = 20 x ((Rdg – Low Limit) / (High Limit – Low Limit))
Parameters
Measurement Unit
Enter the measurement unit symbol or description for the input value and range specified.
Measurement Reading
Add the measurement parameter value in the specified measurement unit you wish to convert.
Lowest Measurement
Enter the lower limit for the measurement range to be converted. For example zero would be a typical value for most instrumentation but you can also add negative (-) or positive (+) values as well. Please enter the value in the same units as specified for all other input values.
Highest Measurement
Enter the upper limit for the measurement range to be converted, e.g. full scale or full range. This value can be negative (-) or positive (+). Please enter the value in the same units as specified for all other input values.
Current Output Signal (0-20mA) – Answer
This is the ideal converted signal for the input measurement range specified, and represents the ideal output reading excluding all measurement and instrumentation errors. The calculated result is displayed in milliamps (mA) based on a linear 0 to 20 mA scaling.
