Example of 3-15 psi to 4-20mA Conversion

A current-to-pressure transducer is used to convert a 4-20 mA electronic signal into a 3-15 PSI pneumatic signal. This particular

An illustration sometimes find helpful in understanding analog signal ranges is to consider the signal range as a length expressed on

The amount of psi can also be calculated from the amount of the milliamp signal, or one can calculate the amount of the milliamp

A pH transmitter has a calibrated range of 4 pH to 10 pH, with a 4-20 mA output signal. Calculate

An electronic temperature transmitter is ranged 50 to 140 degrees Fahrenheit and has a 4-20 mA output signal. Calculate the

A 4 to 20 mA current signal represents a 0 to 100 percent scale. Usually, this scale is linear, as

Calculate the equivalent Percentage for any given current signal 4 to 20 mA. For conversion, we need transmitter’s Lower Range Value

Calculate the equivalent Process Variable for any given percentage of signal ( 0 to 100%). We need Transmitter Span, Lower

Calculate the equivalent 4-20 mA loop current value for any given percentage of signal. We need field transmitter span, lower

The formula for calculating equivalent current (ma) from known process variable (PV), Lower range value (LRV) and Upper range value
