R&D AND DETECTION ADVANTAGES
Jiangsu Zhaolong Electrics Co., Ltd.

Specialty Thermocouples:
We have developed thermocouples for use in solutions such as molten steel, copper, aluminum, and zinc, as well as in salt furnaces, and high-precision, long-life thermocouples suitable for the special environments of cement plants and power plants. Our new anti-oxidation tungsten-rhenium thermocouples are low-cost and offer high temperature measurement, making them an ideal replacement for platinum-rhodium thermocouples; some products meet military standards.

Wireless Temperature Control and Measurement:
We have successively passed ISO9001 quality system certification, ISO14001 environmental management system certification.

Explosion-proof Certification:
In 2013, we obtained national explosion-proof production qualification certificates for explosion-proof thermocouples and resistance temperature detectors (RTDs), ensuring the safety of our products in special environments.

Polytetrafluoroethylene (PTFE) Products:
Our PTFE tubes, plates, rods, gaskets, and custom-shaped parts are resistant to strong acids, strong alkalis, corrosion, and high temperatures, and are widely used in various industries, making them environmentally friendly.

    ADVANCED AUTOMATED MANUFACTURING

    Precision machining equipment and advanced manufacturing technology are used to cut, clean, and anneal thermocouple wires. High-purity platinum, nickel, or copper resistance elements are manufactured, with precision ensured through laser cutting or precision machining.

  • 01
    Quality System
    We adhere to international standards and industry norms to ensure quality at every stage of production.
    02
    Wire Processing
    The thermocouple wires are cut and cleaned to improve their stability and conductivity.
    03
    Component Manufacturing
    Manufacturing high-purity platinum, nickel, or copper resistive components, ensuring accuracy through laser cutting or precision machining.
    04
    Welding
    Welding the metal wires of different thermocouple materials together to form the temperature measuring end; connecting the resistive element to the wire and insulating it.
    05
    Assembly
    The soldered thermocouple or resistance temperature detector (RTD) element is installed in a protective tube or other protective device to ensure it is unaffected by environmental factors during use.
    06
    Encapsulation
    The resistance element is encapsulated in a glass, ceramic, or metal tube. Thermocouples also require suitable protective tubes to ensure their durability and protection.
    07
    Insulation and Explosion-proofing
    Special explosion-proofing treatment is applied to thermocouples and RTDs requiring explosion protection to ensure safe use in hazardous environments.
    08
    Electronic Component Integration
    Thermocouples and other temperature control products jointly developed with multiple institutions in Shanghai are sold well both domestically and internationally with high cost-effectiveness.
