Types of Temperature Sensor | Thermocouple and Thermistors

02/10/2018· Thermocouples are the most commonly used sensing elements in thermal sensors. A thermocouple consists of two conductors of dissimilar metals. The principle of a thermocouple is that these two metals always have a contact potential between them and this potential changes in temperature. To measure the contact potential, two connections or junctions in a circuit are required. …

Thermocouples | Temperature Sensor | RS Components

Thermocouples. A thermocouple is essentially a temperature sensor (a device that measures temperature). It is made up of two wires of different metals that, when joined together, create an electrical junction. When the temperature changes at the junction it creates a voltage that can be interpreted to read the temperature.

Microsensors and Microactuators | Thermocouple | Biosensor

Drawback –for micro thermal transducers the output of thermocouple decreases as the size of the wires and the beads is reduced . Thermocouple are alone not ideal for micro thermal sensors. MICROTHERMOPILE -realistic solution for miniaturized heat sensing thermopiles operate with both hot & cold junction but they are arranged with thermocouples in parallel and voltage output in series.
