temperature thermocouple tip
Inquire NowDescription
The temperature thermocouple tip is a specialized instrument designed for accurately measuring the temperature of molten steel and high-temperature molten metals. This disposable thermocouple operates based on the thermoelectric effect, utilizing the temperature differences between its two sides to provide precise readings. Its construction ensures reliability and ease of use, making it an essential tool for metallurgical applications.
Each thermocouple tip is composed of a temperature measuring probe housed within a protective paper tube, ensuring that it can withstand the harsh conditions of molten substances. The design includes a quartz tube for wire support, and all components are securely bonded with fire-resistant filler, making the thermocouple not only effective but also safe for single-use applications.

Additional Information
- Usage:
- Select the appropriate length of protective paper tube and thermocouple lance based on the object and measurement scope.
- Attach the disposable thermocouple to the lance and calibrate the secondary instrument to zero before measurement.
- Insert the thermocouple into the molten steel at a depth of 300-400mm, avoiding contact with the furnace wall or scum. Limit the immersion time to less than 6 seconds to prevent damage.
- Replace the used thermocouple with a new one and allow a few minutes for preparation before the next measurement.
- Transport and Storage:
- Handle components carefully during assembly and disassembly. Keep dry during transport.
- Store in cases in warehouses with relative humidity less than 80% and ensure proper air circulation free from corrosive gases.
