Based on my previous post about specification of PID parameters, I developed a basic shiny web app to do all of the calculations for you.
Proper specification of PID controller settings ensure that target temperatures are met quickly but not overshot, and cycling of temperature, or more formally, the process variable, is minimized. In an electric brewery, PID settings will be system specific, and will be especially determined by element wattage, liquid volumes, recirculation speed, and other environmental variables.
What’s the purpose of investing in brewery equipment if it is not well calibrated? The most important aspect of calibration is arguably temperature, as temperature during the mashing process has a profound impact on the finished product.
