## 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

## 4-20mA Formulas and Examples

4-20 mA transmitter current output can be converted to the voltage within a specified range, from 0 to a maximal amplitude Vmax,

For any unit conversion on any PLC, you can use four function math with the following for PLC Analog Input

## Scaling Sensor Output to Engineering Units

Sensor Scaling – Converting Current and Voltage Inputs To Engineering Units Such As psi, Deg C, m3/hr etc… Sensor Scaling

## Linear to Square Root Extraction

Some pressure measurements are used to indirectly derive another type of measurand. One of these is the Rate of Flow

## Calculate Temperature Coefficient of RTD

RTD’s are based on the principle that the resistance of a metal increases with temperature. The temperature coefficient of resistance (TCR)

## Relationship between Temperature Scales

Relationship between Temperature Scales Relationship between Fahrenheit and Celsius To determine the relationship between Fahrenheit and Celsius, we could draw

## 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

## Formulas to calculate mA from PV, LRV and URV

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