VI Fundamentals Of The Epoxy Coated NTC Thermistor 30K 3950 Temperature Probe Chip

 

Each temperature sensor style has its own set of operating principles, features, benefits, considerations,

and limitations for optimal use.

 

Thermistors (NTCs and PTCs): Thermistors are thermally sensitive resistors whose prime function is to

exhibit a large, predictable, and precise change in electrical resistance when subjected to a corresponding

change in body temperature. Negative Temperature Coefficient (NTC) thermistors exhibit a decrease in

electrical resistance when subjected to an increase in body temperature. Positive Temperature Coefficient

(PTC) thermistors exhibit an increase in electrical resistance when subjected to an increase in body temperature.

 

RTDs: Platinum Resistance Temperature Detectors (Pt-RTDs) are temperature sensors that have a positive,

predictable, and nearly linear change in resistance when subjected to a corresponding change in their body

temperature.

 

Digital Temperature Indicators: Digital Temperature Indicators have a positive relationship between resistance

and temperature. The response is very much like a digital signal; below the trip temperature, resistance will be

low, above the trip temperature, resistance will be very high. This digital response is ideal for applications where

knowing the temperature has increased beyond a specific value is required. With the digital response, no analog

to digital conversion is necessary, allowing designers to save time and space.
