Temperature Sensors | Fuses Unlimited

A PTC thermistor or Positive Temperature Coefficient thermistor is a temperature sensing device where resistance increases with an increase in the body temperature of the thermistor. An RTD or Resistance Temperature Detector is a device that produces a positive, predictable and nearly linear relationship between its temperature and its ...

RTDs, PTCs, and NTCs: Temperature Sensors | DigiKey

Sep 14, 2011 · Thermistors have a very high sensitivity, and therefore are very responsive to changes in temperature with faster response times than RTDs, but have a smaller temperature range than RTDs. Thermistors have either a negative temperature coefficient (NTC) or a positive temperature coefficient (PTC).

AN2017 - PSoC® 1 Temperature Measurement with Thermistor

Feb 19, 2018 · AN2017 shows how to use PSoC® 1 to accurately measure temperature with a thermistor. The associated project measures the resistance of a thermistor to calculate its temperature using lookup tables and equations, and is also used with other PSoC 1 devices that have the required resources. A thermistor is a temperature-sensitive resistor in ...

Introduction to Temperature Sensors: Thermistors ...

Jun 05, 2017 · The PTC thermistor is not common for temperature measurement but is VERY COMMON when used as a self-resettable fuse. Another common temperature sensor is the silicon diode. It has a very linear temperature coefficient over the normal operating range a semiconductor is used in, typically 0 to 50 C. This range can be stretched some if needed.
