Sep 16, 2020· Furthermore, NTC thermistor resistances at 25 °C are significantly higher than those of the PTC variety. The most common NTC thermistors are 10k and 100k ohms, where PTC are 470 ohms and 1k ohms. Tolerances for PTC thermistors can commonly be 50%, which will not provide an accurate temperature reading without accurate calibration.

ST-300 PRT. The ST-300 is a high accuracy PRT (1/10 DIN) designed to minimize solar load and thermal mass.
The thermistor temperature may be changed by the surrounding temperature or by self-heating the thermistor by passing a current through it. Most applications such as temperature measurement and control or copper coil compensation require that the power dispersed in a thermistor be kept to a minimum so as not to perceptibly self-heat the thermistor.
temperature coefficient, 10 ppm or preferably 5 ppm/°C. 2. The sensor must be well sealed against the ingress of water; any moisture in the probe will affect the reading because the thermistor has a large resistance, comparable to that of a film of water when it bridges the conductors. In many applications, thermistor probes represent a

Temperature sensors are important for everyday life, from working in industrial plants to preventing fires. 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.
Thermistor temperature sensors have broad applicability NTC Thermistors are non-linear resistors that alter their resistance with temperature. Resistance on an NTC probe will decrease predictably as the temperature increases allowing for extremely accurate temperature measurements.
