A temperature sensor detects the temperature of an object or of its environment and converts the reading into an electrical signal. Common types of temperature sensors include thermocouples, resistance temperature detectors (RTDs), thermistors, local temp sensor ICs, and remote thermal diode temperature sensor ICs.
the thermistor sensor can be used to time delay a reaction to changes in conditions in a circuit. If a thermistor is overdriven, the thermal mass time constant of the sensor eventually causes the thermistor to overheat, reducing its resistance. ResistanceVersusTemperature Mode By far, applications using the first mode, resistancever sustemperature, NTC Thermistor configurations, …

Avoid storage of thermistor in harmful environment with effect on function on longterm operation (examples given under operation precautions). Use thermistor within the following period after delivery: Throughhole devices (housed and leaded PTCs): 24 months Motor protection sensors, glassencapsulated sensors and probe assemblies: 24 months
A thermistor is a special resistor whose resistance varies with temperature. Learn how to interface a thermistor with a microcontroller in this tutorial. Introduction to Thermistors There are two types of thermistors: NTC and PTC. Negative Type Coefficient (NTC) thermistors have resistance that decreases when the temperature increases while Positive Type Coefficient (PTC) behaves the …

09/09/2020· The primary difference between the two sensors, other than package size, is the resistance at 25 °C we have a 100k and 10k NTC thermistor, which are the most commonly used values. The datasheets for these two sensors do look fairly linear until you realise that the resistance axis is logarithmic. On a linear scale, like the graph below, we ...
