VI. Frequently Asked Questions (FAQs)

What is the core difference between Type S/R photovoltaic special profile thermocouple and ordinary Type S/R thermocouple?

Answer: The core difference lies in scenario adaptation and structural optimization. This product is a special model for photovoltaic equipment, equipped with multi-point temperature measurement and flexible shielded wire design, adapting to the silicon wafer temperature measurement and complex installation needs of oxidation diffusion furnaces. Ordinary Type S/R thermocouples are mostly general-purpose single-point temperature measurement products without exclusive adaptation design for photovoltaic scenarios.

The product is marked with an operating temperature of 0~1100℃, why can it be adapted to 1200℃ in some scenarios?

Answer: 0~1100℃ is the standard stable operating temperature range. The product materials (Platinum-Rhodium 10 - Platinum, quartz) have a high-temperature resistance capacity of 1200℃, and can work normally in a 1200℃ environment for a short time. However, for long-term use, it is recommended to control the temperature within 0~1100℃ to ensure measurement accuracy and service life.

What is the function of the high-purity corundum core? Can it be replaced with other materials?

Answer: The high-purity corundum core mainly provides internal support and insulation protection. It also has the characteristics of high temperature resistance and strong chemical stability, which is highly compatible with the working conditions of photovoltaic furnaces. It is not recommended to replace it arbitrarily. If it is necessary to adapt to special environments, you can contact the manufacturer to customize a core made of special materials.

The product can be bent arbitrarily, will it affect the temperature measurement accuracy?

Answer: No. The product adopts flexible stainless steel metal shielded wire. Bending will not damage the internal thermocouple core and wire, nor will it affect the transmission of thermoelectric signals. It can be safely adapted to complex installation spaces.

What about the product quality guarantee and after-sales support?

Answer: The product is manufactured by professional manufacturers with a complete quality inspection system and provides corresponding quality assurance services. Professional technical consulting support is available for technical problems during installation, use and assembly. Meanwhile, customized solutions can be provided according to the equipment requirements of customers.
