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?
 
Computer science news on Phys.org
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.
 
This week, I saw a documentary done by the French called Les sacrifiés de l'IA, which was presented by a Canadian show Enquête. If you understand French I recommend it. Very eye-opening. I found a similar documentary in English called The Human Cost of AI: Data workers in the Global South. There is also an interview with Milagros Miceli (appearing in both documentaries) on Youtube: I also found a powerpoint presentation by the economist Uma Rani (appearing in the French documentary), AI...
