Instrumentation Basics – Range Conversion Formula and Examples
In this article, you will learn the instrumentation basics and transmitter range conversion formula, and industry examples.
Formulas
Instrumentation control engineering formulas used in industrial control systems and field instruments like 4-20mA and 3-15 PSI conversions.
Instrument Percent of Span Error
An important part of performing instrument calibration is determining the extent of an instrument’s error. Error is usually measured in
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
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
PLC Raw Count Calculation for Pressure Transmitter
Every instrument has at least one input and at least one output. For instruments responding linearly, the correspondence between input
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,
PLC Analog Input Conversion Formula
For any unit conversion on any PLC, you can use four function math with the following for PLC Analog Input
PLC Problems Troubleshooting
Troubleshooting PLCs can be started by checking the healthiness status of CPU, I/O Modules, Fuse Blow-out and different PLC Failure
PLC Analog Input Scaling
An Allen-Bradley SLC500 programmable logic controller (PLC) uses a 16-bit analog-to-digital converter ( in its model 1746-NI4 ) in analog
