For measuring temperature, you have to measure one of the basic units. For measuring temperature, you have to measure the thermodynamic energy, and for that, the measuring principle is used and where the medium affects the sensor element.
For measuring the temperature using an industrial temperature gauge, you have to reach the same velocity of molecules in sensor and medium. With the same velocity, the two bodies will have the same temperature. It will be achieved by:
- Bodies getting mutual balance,
- The bodies must not exchange heat with external or internal sources and,
- Bodies must have thermal contact for a long time.
4. What is the principle of temperature measurement?
The basic principle of measuring temperature by industrial temperature gauge is through the voltage across the terminals. With the increase in voltage, the temperature also rises after the voltage drop between the base and emitter terminals. Therefore, you can measure the temperature based on electrically measurable changes within the materials when exposed to temperature changes.
These temperature changes could be the changes in resistance in conducting materials, thermal voltage and changes in frequency, noise changes, changes in resistance in semiconductors, etc. The principles used by the industrial temperature gauge are frequency and resistance thermometers.
The temperature change is sensed by a vibrating wire sensor and is converted into an electrical signal as a frequency to a read-out unit.
