Using Raw Anlog Data to convert to usable display

2 posts in this topic

A RTD is hooked up to a ADU206 Compact analog card. The range is 0-80 degrees C. Using the SUB command I can use the decimal value of 2750 to send a shut down at 55 C. I am however also want to take this value and display it in celsuis and not the raw data. Can someone explain/ example on how to perform this? Edited by Fusionworks

Hello, Scaling is: value = (raw in - IR Low) * ((EU high - EU low) / (IR high - IR low)) + EU low IR = Instrument Range EU = Engineering Units If you know the high and low of IR and EU then you can scale the input (raw in ) to the units you need. Good luck, Mark http://www.peakhmi.com
