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) … Zobacz więcej 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 … Zobacz więcej In practical devices, the linear approximation model (above) is accurate only over a limited temperature range. Over wider … Zobacz więcej When a current flows through a thermistor, it generates heat, which raises the temperature of the thermistor above that of its … Zobacz więcej PTC • As current-limiting devices for circuit protection, as replacements for fuses. Current through the device causes a small amount of … Zobacz więcej Thermistors are typically built by using metal oxides. NTC thermistors are manufactured from oxides of the iron group of metals: e.g. chromium ( Zobacz więcej NTC (negative temperature coefficient) Many NTC thermistors are made from a pressed disc, rod, plate, bead or cast chip of semiconducting material such as sintered metal oxides. They work because raising the temperature of a semiconductor increases the … Zobacz więcej The first NTC thermistor was discovered in 1833 by Michael Faraday, who reported on the semiconducting behavior of silver sulfide. … Zobacz więcej WitrynaA thermistor is a contact-type of sensor that offers analog output and interface in a circuit by using a voltage divider network. The potential divider network may also be interfaced with a differential amplifier or the analog input of a microcontroller for the voltage reading. These types of sensors are reliable, highly accurate, and durable.
