Temperature Sensor Types
1. Negatív hőmérsékleti együttható (NTC) termisztor
A thermistor is a thermally sensitive resistor that exhibits a continuous, small, incremental change in resistance correlated to variations in temperature. An NTC thermistor provides higher resistance at low temperatures. As temperature increases, the resistance drops incrementally, according to its R-T table. Small changes reflect accurately due to large changes in resistance per °C. The output of an NTC thermistor is non-linear due to its exponential nature; however, it can be linearized based on its application. The effective operating range is -50 hogy 250 °C for glass encapsulated thermistors or 150°C for standard thermistors.

NTC thermistor is a small size ethoxy-resin-coated thermistor. Used for temperature measurement, NTC(negatív hőmérsékleti együttható) thermistors whose resistance decreases with increasing temperature.
NTC thermistors can be used as electronic circuit elements for instrument temperature compensation and cold end temperature compensation in a variety of applications, providing versatility for automated machine control and industrial instrumentation.
Widely used in household appliances, air conditioning equipment, heating equipment, electric thermometer, liquid level sensor and so on.
Small in size, it can measure the temperature of voids, cavities and blood vessels in organisms that cannot be measured by other thermometers;
These thermistors are easy to use, and the resistance value can be arbitrarily selected between 0.1 and 100kΩ, with good stability and strong overload capacity.

2. Ellenállási hőmérséklet érzékelő (RTD)
A resistance temperature detector, or RTD, changes the resistance of the RTD element with temperature. An RTD consists of a film or, for greater accuracy, a wire wrapped around a ceramic or glass core. Platinum makes up the most accurate RTDs while nickel and copper make RTDs that are lower cost; however, nickel and copper are not as stable or repeatable as platinum. Platinum RTDs offer a highly accurate linear output across -200 hogy 600 °C but are much more expensive than copper or nickel.

3. Thermocouples
A thermocouple consists of two wires of different metals electrically bonded at two points. The varying voltage created between these two dissimilar metals reflects proportional changes in temperature. Thermocouples are nonlinear and require a conversion with a table when used for temperature control and compensation, typically accomplished using a lookup table. Accuracy is low, from 0.5 °C to 5 °C but thermocouples operate across the widest temperature range, from -200 °C to 1750 °C.

4. Semiconductor-based temperature sensors
A semiconductor-based temperature sensor is usually incorporated into integrated circuits (ICs). These sensors utilize two identical diodes with temperature-sensitive voltage vs current characteristics that are used to monitor changes in temperature. They offer a linear response but have the lowest accuracy of the basic sensor types. These temperature sensors also have the slowest responsiveness across the narrowest temperature range (-70 °C to 150 °C).
