The term 'thermistor' is a portmanteau - it is derived from the term THERMally sensitive ResISTOR - and these devices are a very accurate and cost-effective option for temperature measurement. The reasons that thermistors continue to be popular for measuring temperature is: - Their higher rtance change per degree of temperature …
Bimetalic Devices: As per the name of this device the temperature is measured by the means of bimetal i.e. two metals inside the temperature sensor. It is made up of two metals strips having different thermal expansion coefficient. This device works due to the expansion of metals when they are heated.

Jul 9, 2020· For instance, the conventional device, when the temperature of the hot side is fixed at 20 °C, requires 0.88 s to decrease the temperature by 10 °C when a 4 A input current is applied.
As the thermistor heats, it achieves the critical temperature for the device, and the thermistor's temperature radically increases. This characteristic makes it an ideal form of a regulator. Sensor Mode. The sensor mode switching PTC thermistor has minimum current passing through it but senses the temperature of the surroundings.
