What happened when a heat is applied to the joined ends of the wires of a thermocouple

What happened when a heat is applied to the joined ends of the wires of a thermocouple Correct Answer a small voltage is generated

When the heat is applied to the joined ends of the wires of a thermocouple ​a small voltage is generated

Thermocouple:

  • A thermocouple is a sensor used to measure temperature.
  • Thermocouples consist of two wire legs made from different metals.
  • The wire's legs are welded together at one end, creating a junction. This junction is where the temperature is measured.
  • When the junction experiences a change in temperature, a voltage is created. The voltage can then be interpreted to calculate the temperature.

 

This is explained with the help of the following diagram:

The following data pertains to the junction of a thermocouple wire used to measure the temperature of the gas stream. Density = 8500 kg/m3, specific heat = 325 J/kg K, thermal conductivity = 40 W/m K and the heat transfer coefficient between the junction and gas = 215 W/m2 K. If thermocouple junction can be approximated as 1 mm diameter sphere, determine how long it will take for the thermocouple to read 99% of the initial temperature difference

A thermocouple junction in the form of 4 mm radius sphere is to be used to measure the temperature of a gas stream. The junction is initially at 35 degree Celsius and is placed in a gas stream which is at 300 degree Celsius. The thermocouple is removed from the hot gas stream after 10 seconds and kept in still air at 25 degree Celsius with convective coefficient 10 W/m2 K. Find out the time constant of the thermocouple. Assume the thermos-physical properties as given below h = 37.5 W/m2 K p = 7500 kg/m3 c = 400 J/kg K
To effect a bond between two metal plates, 2.5 cm and 15 cm thick, heat is uniformly applied through the thinner plate by a radiant heat source. The bonding must be held at 320 K for a short time. When the heat source is adjusted to have a steady value of 43.5 k W/m2, a thermocouple installed on the side of the thinner plate next to source indicates a temperature of 345 K. Calculate the temperature gradient for heat conduction through thinner plate. In the diagram, the upper plate is 2.5 cm thick while the lower is 15 cm thick.
