Thermistor Wikipedia

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), selfresetting overcurrent protectors, and selfregulating heating elements (positive ...

The types of thermistors found in a vehicle exhaust environment will typically produce a negative temperature coefficient (NTC), meaning the resistance will decrease with increasing temperature. Thermistors offer a high sensitivity over a smaller range in temperature than either thermocouples or RTDs. At 0°C the resistance can be over 100,000 Ω,at 200°C 200 to 500 :, and at 800°C 50:.

Difference Between a Thermostat and Thermistor | Hunker

A thermistor is based on the same principle as a thermostat, but it is used in a different manner. A thermistor uses a metallic oxide compound such as cobalt or manganese. The principle is that the conductivity of the metallic oxide changes according to temperature. Depending on the metallic oxide compound used, usually the conductivity increases as temperature increases; the amount of ...

Temperature Sensors. Thermistors vs Thermocouples

Thermistors and thermocouples are two such temperature sensors. A thermistor is a thermally sensitive resistor that exhibits a continuous, small, incremental change in resistance correlated to temperature variations. Thermocouples reflect proportional changes in temperature through the varying voltage created between two dissimilar metals electrically bonded together. Both are good options for ...

What Is An NTC Thermistor | Ametherm

NTC Thermistors are nonlinear resistors, which alter their resistance characteristics with temperature. The resistance of NTC will decrease as the temperature increases. The manner in which the resistance decreases is related to a constant known in the electronics industry as beta, or ß. Beta is measured in °K. NTC Thermistor Probes.
