Transient thermal resistance is a response of a device to a single pulse expressed in terms of the pulse duration.The thermally limited region of the SOA is calculated based on transient thermal resistance.Transient thermal resistance is used to calculate a rise in junction temperature caused by the application of instantaneous pulse power.Fundamentals of industrial temperature sensors Apr 10,2021·Target use of thermal variation modeling in temperature sensors.Source Ross-Pinnock and Maropoulos .Temperature sensors are widely used to quantify temperature fluctuations.This is done by converting thermal energy from an object into electrical signals with either contact sensors or non-contact sensors using one of the two main signal RTD - Resistance Temperature DetectorThe RTD sensors can be made small enough to have response times of a fraction of a second.To measure the resistance of an RTD a small electric current (about 1 mA) must flow through the sensor to create the necessary voltage drop.The current causes the platinum element in the RTD to heat up above the temperature of the RTD's environment (Also
