AI Thread Summary
Thermistors, or thermally sensitive resistors, are crucial for temperature-sensitive devices in control circuits due to their high sensitivity to temperature variations. Compensation refers to the ability of thermistors to adjust for changes in circuit properties caused by temperature fluctuations. When a circuit's characteristics change with temperature, thermistors can alter their resistance to counteract these changes, ensuring stable performance. They are often integrated into bridge circuits, where their stability and sensitivity are enhanced. In these configurations, small temperature changes lead to corresponding changes in the thermistor's resistivity, allowing for precise calibration of devices like DROs (Dielectric Resonator Oscillators) to accurately measure energy transduced by temperature variations.

Thermistors---THERMally sensitive resISTOR are used to make temperature sensitive devices useful in temperature control circuits. This high sensitivity to temperature changes makes the thermistor extremely useful for precision temperature measurements, control and compensation.

My question is what is compensation? How are thermistors used as compensating devices?

I suppose if some property of a circuit changes with temperature, and that change can be compensated for by a change in resistance, then that is the compensation they might be alluding to.
 
Thank you for replying, but can someone explain in detail how this works?
 
Thermistors are usually used in bridge ckts (Resistive) where the stability and sensivity of Thermistor is enhanced when present in the Bridge ckt.
Small changes in temperature correspondingly change the resistivity of the Thermistor and a device ( DRO or something ) is caliberated accordingly to measure the transduced energy.
 
In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...
Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
