How to do 4-20mA Conversions Easily
Generally it is possible to generate a “custom” linear equation in the form of y = mx + b for any linear responding instrument relating input directly to output, a more general
4-20mA Graphical Calculations
An illustration sometimes find helpful in understanding analog signal ranges is to consider the signal range as a length expressed on a number line. For example, the common 4-20 mA analog current
Why 4-20mA Standard is so popular ?
4-20mA Standard 4-20mA has an inherent ‘live zero’. Zero engineering units is 4.0mA, not 0.0mA. 0.0mA indicates an open circuit, a failure or a fault mode like cut wires or
Formula to Calculate 3-15psi from 4-20mA Current
The amount of psi can also be calculated from the amount of the milliamp signal, or one can calculate the amount of the milliamp signal when the amount of psi is known. Each of
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 transducer is configured for reverse action instead of direct, meaning
Calculate Process Variable from Transmitter Current
A pH transmitter has a calibrated range of 4 pH to 10 pH, with a 4-20 mA output signal. Calculate the pH sensed by the transmitter if its output signal
Calculate Temperature Transmitter Output
An electronic temperature transmitter is ranged 50 to 140 degrees Fahrenheit and has a 4-20 mA output signal. Calculate the current output by this transmitter if the measured temperature is
Standard 4 to 20 mA Conversion Formula
A 4 to 20 mA current signal represents a 0 to 100 percent scale. Usually, this scale is linear, as such: Being a linear function, we may use the standard
Formula for Current 4-20ma to Percentage Conversion
Calculating the equivalent Percentage for any given current signal 4-20ma. Formula for Current 4-20ma to Percentage Conversion Formula: Percentage, % = ((X-4)/16)(100) Where X is current signal in
