What is the structure of the Oven Thermocouple?

1. Thermal sensor: The thermal sensor of Oven Thermocouple is one of its core components. Its basic principle is to utilize the thermocouple effect of two different metal wires. The two metal wires form a closed loop at the point of connection called a thermocouple solder joint. When a thermal element is exposed to a high temperature environment, the heat from the metal wire will cause the thermocouple to produce a voltage that is proportional to the temperature. Therefore, by measuring the voltage generated by the thermocouple, the temperature of the oven can be accurately determined.

The design and material selection of thermal components are crucial. Metals with good high-temperature stability and corrosion resistance are usually selected, such as copper, platinum, nickel or chromium. These materials can maintain stable thermoelectric properties under long-term high-temperature environments, ensuring measurement accuracy and reliability.

2. Protective shell: The heat-sensitive element of the Oven Thermocouple is often located in a protective shell to prevent the external environment from affecting the sensor. The protective shell is usually made of high-temperature and corrosion-resistant materials such as high-temperature ceramics or stainless steel. This kind of shell can effectively isolate the thermal element from contact with air, steam, grease and other substances inside the oven, preventing it from being contaminated and damaged, thereby ensuring the accuracy and stability of measurement.

The protective shell also has good thermal conductivity, which helps the thermal element respond quickly to temperature changes and improves the sensitivity and accuracy of measurement. At the same time, it can also protect the thermal sensitive element from mechanical damage and external impact, extending the service life of the sensor.

3. Connecting cables: The thermal element of the Oven Thermocouple is connected to the temperature display or controller via one or more connecting cables. These connecting cables usually use high-temperature cable materials, such as mineral insulated cables or silicone rubber cables, which have excellent high-temperature resistance and insulation properties and can safely and reliably transmit signals in high-temperature environments.

The selection of connecting cables must take into account stability and durability under long-term high temperatures to ensure a stable connection between the sensor and the temperature display or controller and accurately transmit the temperature signal.

4. Terminal: The connecting cable of the Oven Thermocouple is usually connected to the temperature display or controller through the terminal. The terminal block is an important connection component for securely connecting the connecting cable to the temperature display or controller. The terminals are usually made of metal or ceramic materials and have good high temperature resistance and electrical connection properties.

The design of the terminal must comply with standard specifications to ensure a safe and reliable connection between the cable and the display or controller, while ensuring good electrical signal transmission to ensure the accuracy of temperature measurement.

5. Mounting Parts: The Oven Thermocouple's mounting parts are used to install the sensor at the appropriate location inside the oven to ensure accurate temperature measurement. Installation components usually include various clamping devices, fixed brackets or hooks, etc. Select the appropriate installation method according to the design and structure of the oven. The selection and installation location of mounting components have an important impact on the accuracy and stability of temperature measurement.
