Thermistor characteristics: As just mentioned above, resistance increase with increase in temperature for PTC and resistance decrease with increase in temperature for NTC. The thermistor exhibits a highly non-linear characteristic of resistance vs temperature. NTC Thermistor Characteristics Curve. Notice that it has a negative temperature coefficient ( NTC), that is its resistance decreases with increasing temperatures. Using a Thermistor to Measure Temperature. A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor. Thermistors are widely used as inrush current limiters, temperature sensors (Negative Temperature Coefficient or NTC type typically) 1.2 Linearizing the R/T characteristic NTC thermistors exhibit a distinctly non-linear R/T characteristic. If a fairly linear curve is required for measurements over a (wide) temperature range, e.g. for a scale, series-connected or paral-leled resistors are quite useful.
Characteristic NTC curve. As can be seen from the figure, the NTC thermistors have a much steeper resistance-temperature slope compared to platinum alloy RTDs, which translates to better temperature sensitivity.
Further Modelling of NTC Thermistor R/T CharacteristicsThe equation is derived from mathematical curve-fitting techniques and examination of the Resistance versus Temperature characteristic of thermistor devices. R/T Curve Characteristic The resistance vs. temperature relationship of an NTC thermistor over a temperature span is nonlinear therefore, an NTC thermistor R/T characteristic is typically designated by its "curve". (i.e. Curve Z characteristic). Introduction. NTC Thermistors are ceramic semi-conductor elements made from metal oxides which have a predictable and repeatable R-T curve.The combination of a NTC thermistor and a resistor connected in parallel will produce an S shaped characteristic curve. n Negative Temperature Coefficient Thermistor (NTC Thermistor).The B-value is an index of thermal sensitivity and represents slope of R/T curves.
