In industrial production, extreme environments such as high temperature, strong wear and tear, and strong corrosion pose severe challenges to temperature measurement equipment. Anhui Jinling Automation Co., Ltd., with its wear-resistant thermistor and thermocouple series, utilizes unique processes andexcellentPerformance, becoming the preferred temperature measurement solution for power plants, cement plants, chemical smelting and other fields. These two types of products have demonstrated significant advantages in terms of wear resistance, high temperature resistance, and stability through material innovation and structural optimization.

Wear resistant alloy technology: the cornerstone of improving service life

Jinling wear-resistant thermistor/thermocoupleThe core breakthrough lies in the research and development of wear-resistant alloy protective tubes. It adopts high-voltage electric pulse cladding technology to fuse tungsten carbon compounds with601Stainless steel substrate instantly fuses at ultra-high temperatures, forming a hardness of up toHRC62-65The composite layer. This hardness far exceeds that of ordinary stainless steel（HRC≤30）Even better than metal ceramic materials, it can withstand≤100m/sFluid erosion and mechanical vibration. For example, in a circulating fluidized bed boiler, ordinary wear-resistant alloy protective tubes can only maintain10-90Tian, and Jinling products have been verified by hundreds of enterprises and nearly 10000 practical applications every year, extending their service life to1-5In years, some scenes can even reach2Significantly reduce downtime maintenance costs.

Structural optimization: intelligent design adapted to complex working conditions

Armored structure: The thermal resistor adopts an armored design, integrating the temperature sensing element, lead wire, insulation material and stainless steel sleeve into a single piece, with a minimum outer diameter of up toφ1mmThis structure is not only compact in size and easy to install in narrow pipelines or equipment with frequent vibrations, but also shortens the thermal response time to that of ordinary thermal resistors through the characteristic of no air gap inside1/3The measurement lag is less than1In seconds.

End face temperature measurement: For special scenarios such as bearing shells and mechanical end faces, Jinling has developed end face type thermistors. Its temperature sensing element is closely attached to the measured surface, directly reflecting the true temperature, avoiding errors caused by poor contact during axial installation, and achieving high accuracy±1℃, with better reproducibility than0.5℃.

Three wire wiring: The thermal resistor adopts three wire technology, which compensates for the influence of lead resistance through additional wires, eliminates the interference of environmental temperature fluctuations on measurement accuracy, and ensures-200℃to1800℃Stable operation within a wide temperature range.

Performance Comparison: Differentiated Advantages of Thermistors and Thermocouples

Thermistor: Platinum based（Pt100ThePt1000）Copper can be used as a temperature sensing material, with high linearity and stability, in the medium and low temperature range（-200℃to850℃）Accuracy can reach±0.1℃Suitable for scenarios with strict temperature control requirements such as chemical reaction vessels and pharmaceutical sterilization cabinets. Its pressure spring type temperature sensing element has excellent anti vibration performance, and can maintain measurement stability even in a vibration environment for a long time.

Thermocouple: using platinum rhodium-Platinum, nickel chromium-The combination of nickel silicon and other materials expands the temperature measurement range to-200℃to2500℃Especially suitable for extreme environments such as high-temperature furnaces and burners. Its thermal response time only takes a few hundred milliseconds and does not require external power supply, ensuring high safety. For example, in a sulfur dioxide combustion furnace, the Jinling thermocouple achieves explosion-proof design through a specially structured junction box to prevent safety accidents caused by explosive gases.

Industry Application: Verification from Theory to Practice

Jinling products have been widely used throughout the country300Yu enterprises cover four major fields: electricity, cement, chemical industry, and metallurgy. In a cement plant kiln hood renovation project, traditional thermocouples were frequently damaged due to insufficient wear resistance. After replacing them with Jinling wear-resistant thermocouples, the annual failure rate increased from12Reduced to2Secondly, the annual cost savings of spare parts exceed50Ten thousand yuan. In a circulating fluidized bed boiler of a certain power plant, the armored thermal resistance operates continuously due to its anti erosion characteristics18No measurement deviation for months, helping to improve boiler efficiency3%.
