So I'm beginning to set up a RIMS system and would like to monitor temperature at several places in the process. However, thermocouples and readouts can start to get both bulky and pricey! What I want is a simple measurement device and a simple readout.
So, what to do but build my own circuit! Here's what I've come up with.
This circuit uses the LM34 IC for the temperature measurement. It prodcues 10mV/degree F. I set up a voltage divider to divide this value by 10, giving 1mV/degree F. Then I just hook up a 200mV voltmeter to readout my temperature directly!
I've ordered the parts and they just arrived. I'll be doing some testing this evening and will post up photos and results. My total cost was $50 which will allow me to set up 3 measurements and 3 read outs. That's a little over $15 each!
