WebIt uses three coefficients to characterize the NTC material with great accuracy. The Steinhart–Hart equation is a model of the resistance of a semiconductor at different temperatures. The equation is: 1 T = A + B ln ( R) + C ( ln ( R)) 3 where: T is the temperature (in kelvins) R is the resistance at T (in ohms)
WebNov 25, 2024 · How Does a Thermistor Work? 1. NTC or PTC A thermistor’s most basic feature may be whether its resistance goes up or down with increasing temperature. Those that lose resistance have a negative temperature coefficient (NTC), while those that gain resistance have a positive temperature coefficient (PTC). WebA thermistor is a semiconductor type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a portmanteau of thermal and resistor . Thermistors are divided based on their conduction model.
