Aug 28, 2018· Thermistors, derived from the term thermaIly sensitive resistors, are a very accurate and cost- effective sensor for measuring temperature. Available in 2 types, NTC (negative temperature coefficient) and PTC (positive temperature coefficient), it is the NTC thermistor that is commonly used to measure temperature.
Sep 09, 2020· An NTC Thermistor is a resistor in which the resistance drops as the temperature increases. This allows typical methods of measuring resistance in a circuit to calculate the temperature of the resistor. Unfortunately, the temperature change is non-linear, which means you cannot directly measure temperature change by the change in resistance.
A thermistor’s system electronics need to match the curve of sensor. Whereas in RTDs there is a positive correlation between resistance and temperature (as temperature increases, resistance increases as well), in negative temperature coefficient (NTC) thermistors, the inverse relationship holds (resistance decreases as temperature increases).
Aug 13, 2015· Thermistors are mainly used as temperature sensors, inrush current limiters, self-resetting over-current protectors and self-regulating heating elements. A thermistor is made from a semiconductor material. It is shaped into a disc, a rod or a bead. Bead thermistors may be only a few millimetres in diameter.
A: Response time is defined as the time it takes to reach 62% or a new temperature, and is a function of mass. The smaller the sensor the faster the response. A discrete sensor will respond faster than the same sensor packaged inside a metal housing. Typical response times for a Series I NTC thermistor sensor is <15 seconds.

A thermistor is a temperature sensor whose electrical resistance changes in response to a change in body temperature. Though the initial concept of an NTC thermistor was first reported in 1833 by Michael Faraday, when he discovered the effect of temperature on silver sulfide, it wasn’t until the 1930’s when the first commercial thermistors were produced.

Beta tolerance: Is the tolerance of a thermistor’s beta value β, determined by the composition and structure of the metal oxides being used in the sensor. For bead-type thermistors, beta tolerances are in the order of ±1% to ±5%; for metallized surface contact type, beta tolerances range from ±% to ± 3%.

Temperature Range: The approximate overall range of temperatures in which a sensor type can be used. Within a given temperature range, some sensors work better than others. Relative Cost: Relative cost as these sensors are compared to one another. For example, thermistors are inexpensive in relation to RTDs, partly because the material of choice for RTDs is platinum.
