Agitator Temperature Sensors

...

Note: the Agitator temperature sensors are reporting values that are about 2x the actual temperature. As of June 2023, we have not yet determined the cause of this.

Topic	Description	Notes
Diagram of the measurement circuit used for the temperature sensors.	Image Added The AD592 is powered by 12V (supplied by the Galil) The AD592 outputs 1 micro-Amp / K. The 10k Ohm resistor converts this amperage change to a voltage change (via Ohm’s law): V = I*R 0.01 V/K = 1 uA/K * 10^4 Ohm. This voltage change is then sensed by the Galil’s ADC.	Originally from Dale Sandford (UCO).
Galil ADC calculations for the AD592 temperature sensors.	12 bit over 5V = 0.001 V per ADU; AD592 gives 0.01 V per K; So measurement resolution is: 0.1 K per ADU (OK for these sensors)	Based on values within datasheet below.
