Calculating the equivalent Percentage for any given Process variable.
Formula for Process Variable to Percentage Conversion

| Formula for Process Variable to Percentage Conversion |
Formula:
Percentage % = ((Process Variable – LRV)/Span)(100)
Span = URV-LRV
Where
URV upper range value
LRV lower range value
Example:
An electronic Pressure transmitter is ranged -1 to 5 Bar and has a 4-20 ma. Calculate the Percentage output by this transmitter if the measured Pressure is 1 Bar
Span = 5 – (-1) = 6
Percentage % = ((Process variable – LRV)/Span)(100)
=((1-(-1))/6)(100)
= 33.33 %
