| Product Overview
The WCTST803 series corundum tube thermocouple researched and produced by winchen sensor is an assembled high-temperature temperature sensor, mainly consisting of a corundum protection tube, a temperature sensing element, a terminal box, mounting fittings and a compensating lead wire. The corundum protection tube is made mainly of high-purity alumina and offers excellent high-temperature insulation, thermal shock resistance and corrosion resistance, enabling stable temperature measurement in oxidizing and inert atmospheres. The WCTST803 series corundum tube thermocouple is available in K, N, S, R and B types, among which the highest measurable temperature is 1700°C, °C. It is used in high-temperature applications such as lithium battery kilns, glass melting furnaces, metallurgical furnaces, ceramic kilns, vacuum furnaces and laboratory electric furnaces, and non-standard customization is supported.
| Features
1. High-purity corundum protection tube: Al₂O₃ content≥≥99%, reliable insulation at high temperature and resistant to deformation.
2. Strong high-temperature performance: long-term service temperature up to 1600°C and short-term up to 1800°C (depending on calibration type, tube diameter and working conditions).
3. Good thermal shock resistance: adapts to frequent heating and cooling cycles, reducing the risk of protection tube cracking.
4. Corrosion resistant: suitable for oxidizing and inert atmospheres and a variety of melt environments.
5. Accurate and stable measurement: can be fitted with K, N, S, R, B and other calibration types, with high accuracy and small long-term drift.
6. Customizable structure: tube diameter, insertion length, flange, thread, terminal box and compensating lead wire can all be customized on demand.
7. Easy installation: suitable for many installation scenarios such as furnaces and kilns, pipelines, reactors and high-temperature equipment.
8. Long service life: oxidation and contamination resistant at high temperature, suitable for continuous operation and harsh conditions.
