What is Thermistor: Definition and 57 Discussions

A thermistor is a type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word is a combination of thermal and resistor. Thermistors are widely used as inrush current limiters, temperature sensors (negative temperature coefficient or NTC type typically), self-resetting overcurrent protectors, and self-regulating heating elements (positive temperature coefficient or PTC type typically). An operational temperature range of a thermistor is dependent on the probe type and is typically in between −100 °C (173 K) and 300 °C (573 K).

    Can Thermistors Be Used as Compensating Devices in Temperature Control Circuits?

    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...

    Sensor project relating to thermistor

    Howdy, I'm want to make a sensor dealing with thermistors, and i just don't know where to begin...Can someone please help me get started? The project can be anything...but I am leaning towards measuring the temperatures vs time. using thermistors. Any help would be greatly appreciated.

    Method and circuit for an NTC thermistor experiment

    I am currently studying a coursewok set on sensors. If anyone knows the method and circuit for an NTC thermistor experiment or any information on the thermistors at all it would be greatly appriciated.

    Applications of non linear thermistor

    Bit of a strange one this: Can anyone think of any real life applications where having a non linear thermistor (like one that didnt change a set amount of resistance for the same temperature change) would cause any problems?

    How do I calibrate a thermistor for measuring the melting point of a chemical?

    For the "build your own sensor" part of my AS work I am using a thermistor in a potential divider in order to measure the melting point of a chemical. My teacher has OKed this but says that i need to calibrate the sensor in, for example, melting ice. I am not sure exactly what this involves...

    Thermistor Testing & Calibration: Coursework Help

    Hi please help I have to do a piece of coursework on sensors. I am testing a thermistor and my teacher mentioned something about calibration but I don't know what it is can someone help please. I have taken results for the resistances for every ten degrees from 0 to 150
