WebNov 25, 2024 · How Does a Thermistor Work? 1. NTC or PTC A thermistor’s most basic feature may be whether its resistance goes up or down with increasing temperature. …
WebA 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 divided based on their conduction model. WebAt least another important characteristic should be mentioned, the beta value. You can have two different 10k thermistors with different beta values, and they will give you different readings. So this is an important parameter to know, at least if you need accuracy and not just some ballpark temperature.

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 divided based on their conduction model. Negative Temperature Coefficient (NTC) … See more 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 … 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 … See more The first NTC thermistor was discovered in 1833 by Michael Faraday, who reported on the semiconducting behavior of silver sulfide. Faraday noticed that the resistance of silver sulfide decreased dramatically as temperature increased. (This was also the … See more Thermistors are typically built by using metal oxides. NTC thermistors are manufactured from oxides of the iron group of metals: e.g. chromium (CrO, Cr2O3), manganese (e.g. MnO), cobalt (CoO), iron (iron oxides), and nickel ( See more NTC (negative temperature coefficient) Many NTC thermistors are made from a pressed disc, rod, plate, bead or cast chip of See more PTC • As current-limiting devices for circuit protection, as replacements for fuses. Current through the device causes a small amount of resistive heating. If the current is large enough to generate more heat than the device can … See more cyril pearlWebOct 17, 2024 · 1 Answer. The resistance of a thermistor changes with temperature. How much the resistance changes depends on the type of material used in the thermistor. Unlike other sensors, thermistors are nonlinear, meaning the points on a graph representing the relationship between resistance and temperature will not form a straight line. cyril pharmasave ottawaWebAug 12, 2024 · The wax (blue) is inside a sealed chamber (gray) that contains a metal needle (silver).
