Johnson Controls, Inc. A99B Series Temperature Sensor

Q: Would this probe fit inside a 1/4" ID given that its own diameter is nominally 0.25" as well?

Really not sure. I used a larger PVC pipe to feed it through a wall, then sealed it with expanding foam insulation.

Q: Is this sensor ratiometric with resistance according to input voltage?

I think you're asking if this is a thermister. The answer is yes. The resistance changes with temperature.

Q: Would this probe fit inside a 1/4" ID given that its own diameter is nominally 0.25" as well?

The probe end would not be able to fit in a 1/4" ID.

Q: Can I use this probe to measure liquid temperature (of wine inside a bottle to control wine chiller temp)? Can it be made waterproof?

You should be able to cover with a food grade sheath.
