Resistance of thermistor
WebSep 7, 2024 · You can use the Steinhart-Hart equation to convert thermistor resistance to temperature. Depending on the base resistance, it gives accuracy within a limited temperature range of about 50ºC around the given temperature. You will need lower resistance thermistors ranging from 2252 to 10,000Ω for low-temperature applications. WebThe Thermistor block represents an NTC thermistor using the B-parameter equation. The resistance at temperature T is. R = R 0 e B ( 1 / T − 1 / T 0) where: R0 is the nominal resistance at the reference temperature T0. B is the characteristic temperature constant. The following equation describes the thermal behavior of the block:

WebA thermistor is a non-ohmic conductor and sensory resistor whose resistance varies with temperature. Most thermistors are negative temperature coefficient (ntc) components. … Depending on materials used, thermistors are classified into two types: With NTC thermistors, resistance decreases as temperature rises; usually due to an increase in conduction electrons bumped up by thermal agitation from the valence band. An NTC is commonly used as a temperature sensor, or in series with a … See more A thermistor is a semiconductor type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a portmanteau of thermal and resistor. Thermistors are … See more In practical devices, the linear approximation model (above) is accurate only over a limited temperature range. Over wider temperature ranges, a more complex … See more When a current flows through a thermistor, it generates heat, which raises the temperature of the thermistor above that of its environment. If the thermistor is being used to measure the temperature of the environment, this electrical heating may introduce a … See more The first NTC thermistor was discovered in 1833 by Michael Faraday, who reported on the semiconducting behavior of silver sulfide.
