WRNK wear-resistant thermocouples are equipped with wear-resistant sleeves made of special materials and specifications. In high wear environments such as cement plants and ball mills, their wear resistance is superior to ordinary thermocouples, and their service life can be several times that of ordinary products, reducing replacement frequency and maintenance costs. Capable of stable operation in special high-temperature environments, suitable for high-temperature process scenarios such as metallurgy and chemical engineering.

Due to its small volume and low thermal inertia, WRNK wear-resistant thermocouples respond quickly to temperature changes, making them particularly suitable for dynamic temperature measurement, such as temperature monitoring of molten metals or rapidly heating furnaces. Direct contact with the measured medium avoids interference from intermediate media, and combined with good linearity of thermoelectric potential output, it can still maintain high measurement accuracy and stability in long-term use.

The design of wear-resistant sleeves not only enhances their wear resistance, but also improves their resistance to vibration and thermal shock, ensuring reliable operation even under frequent temperature fluctuations or mechanical vibrations. With its unique thermoelectric effect principle and optimized structural design, it has demonstrated advantages in high temperature, high wear, and complex industrial environments, becoming an important tool for improving production efficiency and process control accuracy.

Precautions for using WRNK wear-resistant thermocouple:

1. Installation points: When connecting cable wires to the corresponding signal conditioner or display device, it is necessary to connect them according to the correct electrode pairing to prevent erroneous signals and affect measurement accuracy. For welding type wear-resistant thermocouples, insulation coating should be applied during installation to avoid burning out. Before connecting cable wires, the remaining cables should be wrapped with tape to reduce interference and electromagnetic wave effects.

2. Disassembly precautions: Protect the wear-resistant head. It is strictly prohibited to strike, collide or vibrate the wear-resistant head to avoid cracks, detachment or fracture of the wear-resistant layer due to mechanical force. When disassembling, special tools (such as wrenches) should be used to operate slowly, avoiding forcibly pulling or twisting the connection between the wear-resistant head and the protective tube.

3. Regular calibration: This high-precision sensor requires regular calibration, which is not only the key to ensuring data reliability, but also a mandatory requirement to comply with industry standards. During the calibration process, technicians will simultaneously inspect the appearance and insulation performance of the sensor (such as insulation resistance at room temperature ≥ 100M Ω). If any damage is found, it can be repaired in a timely manner to avoid measurement failure caused by local damage expansion, indirectly extending the service life of the equipment.
