RIMS Sensor Placement
Research the web and you'll see that there are four recommended temperature sensor placements for your RIMS Tube system. They are:
Location A - At the outlet of
your RIMS Tube
RIMS Tube Circulation
Before placing your RIMS tube sensor consider this:
Just like the animated GIF below shows, heat takes time to propagate through your system. This means that when your RIMS Tube element turns on, the temperature change takes time to propagate or move through your system. How long depends on the size of your mash, your false bottom restriction, pump size, tubing size and heating element size.
Placing your sensor in any location but location A can cause your mash temperature to spike. This is because the further away from your RIMS tube the more time the heating element will be on before your PID measures and reacts to the temperature change!
The worse place to put your sensor is location D - your RIMS Tube inlet because any temperature change will have to flow completely through your system before your sensor will pick up any difference! Location C is almost as bad because it's only a little more up stream.
Location B is a great place to put an independent thermometer to monitor your mash temperature.
