Thermocouple alloy and junction selection
Thermocouple Universal: Match thermocouple type, polarity and extension cable to the controller input. Select protection-tube material and grounded or ungrounded junction for the atmosphere, electrical noise and response required.
Define insertion depth and the mechanical support at the process connection. A temperature stated in a product name needs confirmation for the complete probe assembly, cable transition and continuous duty.
For Thermocouple Universal, send the controller input, required measurement range, accuracy, probe drawing and cable or connector details. Ask for the agreed sensor designation and inspection requirements on the quotation.
Application and reference configuration
Industrial temperature monitoring and furnace control. The final suitability of Thermocouple Universal depends on the assembled equipment and agreed operating conditions.
Archived figures below describe reference options or a product series. Confirm the exact model specification in the quotation.

ARCHIVED PRODUCT INFORMATION
Description
The thermocouple for gas stoves is a temperature sensor that operates based on the thermoelectric effect. It consists of two different metals welded into a thermocouple wire. When heated by a flame, a small electric current (thermoelectric potential) is generated due to the temperature difference between the two metals. This signal is transmitted to the gas valve controller to keep the valve open. When the flame is extinguished, the current disappears, and the valve automatically closes to prevent gas leakage.

Advantages
Safety Assurance: It can monitor the flame status in real - time. Once the flame is accidentally extinguished, it can quickly and automatically cut off the gas supply, effectively preventing gas leakage and reducing the risks of fire and explosion, thus safeguarding the lives and property of users. For example, when water overflows and extinguishes the flame while boiling water, the thermocouple can respond promptly.
Precise Temperature Control: It converts the flame temperature into an electrical signal to accurately control the gas flow, enabling precise adjustment of the firepower to meet different cooking requirements. Whether it's frying, stir - frying, boiling or deep - frying, it can perform well.
Energy - saving and High - efficiency: It precisely controls the gas flow, enabling the gas to burn fully and improving the combustion efficiency, reducing energy waste. In the long run, it can save gas costs.
High Stability: It is less affected by environmental factors, has reliable performance and a relatively long service life, reducing the cost of frequent repairs and replacements. Some thermocouple products have strong oxidation resistance and can work stably in high - temperature environments.
Cost - effectiveness: Compared with some other flame - out protection devices (such as ion - sensing devices), it has a relatively low overall cost, high cost - performance ratio, and is suitable for large - scale production and popularization.
Convenient Installation and Maintenance: It has a relatively simple structure, is easy to install, and its daily cleaning and maintenance are not complicated, with a low operation difficulty for users.
Classification by Material and Characteristics
Type K Thermocouple: Composed of nickel - chromium and nickel - silicon (nickel - aluminum) alloys. It has a wide temperature measurement range (-200°C - 1260°C), stable performance at high temperatures, and strong oxidation resistance. It is widely used in various gas stoves and can adapt to high - temperature combustion environments.
Type J Thermocouple: Made of iron - constantan alloy. The general temperature measurement range is between - 210°C - 1000°C. It has certain stability at high temperatures, but compared with Type K, its corrosion resistance is slightly weaker, and the cost is relatively low.
Type T Thermocouple: Composed of copper - constantan alloy. It has high sensitivity in the low - temperature range (-200°C - 350°C). However, when used in gas stoves, its high - temperature performance is inferior to that of Type K and Type J, and it is relatively less used in household gas stoves.
Type E Thermocouple: Made of nickel - chromium - constantan alloy. Among common thermocouples, it has a relatively high thermoelectric power rate (sensitivity), that is, the electrical signal changes significantly when the temperature changes. It is suitable for some gas stoves that are sensitive to temperature changes and require precise temperature control.
Type N Thermocouple: Composed of nickel - chromium - silicon and nickel - silicon - magnesium alloys. It has good high - temperature stability, strong corrosion resistance, and a long service life. It can work stably in harsh combustion environments and is often used in high - end or commercial gas stoves.
Classification by Structural Form
Split - type Thermocouple: The sensing part and the connecting part are relatively independent. During installation and maintenance, components such as the sensing head or connecting wires can be disassembled separately. If a certain part is damaged, replacement is relatively convenient.
Pulse Integrated Thermocouple: Integrates the sensing function of the thermocouple with functions such as pulse ignition. It simplifies the internal structure, reduces the connections between components, and reduces the probability of failure, making the ignition and flame - out protection control of the gas stove more efficient and stable.
