Sensor type?

[ptonsparky]

I have the the two wire temperature sensor from this damaged control? Is there a way to tell what type it is?

Yes

Yes

Thank you!
You are close to my heart.

Google info on the controller?

Duh...this one.
I looked a year or two ago.
I'll try again

Use an ohmmeter to measure resistance. Use both polarities. If the same resistance for both polarities, and resistance is in the range of possibly 40 ohms to 10,000 ohms it may be a thermistor. Change its temperature from room to 0 F to possibly 140 F for a test.

1. Does resistance change, and remain of same value for both + and - polarity? If so, then it is probably a thermister.
2. Change to a low millivolt range. Change temperature. Does voltage change with temperature? Maybe works in one polarity vs other. If voltage changes, then probably a thermal generator.

From manufacturer's data sheets : Probe is a PTC model A99BB-200C. The "200C" changes with probe length and connection style

The control itself is defunct.

You can get thermistor tripping relay from numerous source if it’s just an On-Off control point.
