Industry knowledge

Accurate temperature measurement is critical in modern industrial processes. In industries such as chemical processing, natural gas production, and petroleum refining, precise temperature data ensures safe operations, optimized process control, and high equipment efficiency. Resistance Temperature Detectors (RTDs) are widely used in these sectors because they provide reliable, high-precision measurements and can operate stably under a variety of industrial conditions.

RTDs measure temperature by detecting changes in the electrical resistance of a metallic element, usually platinum, which changes predictably with temperature. This design makes RTDs ideal for continuous monitoring in industrial environments where accuracy and stability are crucial.

1. Product Features and Advantages

Key features of Jiangsu Zhaolong Electrics RTDs include:

  • High Accuracy: RTDs are engineered to deliver precise and consistent temperature readings, reducing the risk of process deviation and improving overall system reliability.
  • Durable Construction: Protective sheaths made of stainless steel or specialized alloys resist corrosion, vibration, and mechanical stress, ensuring long-term stability in harsh industrial environments.
  • Wide Temperature Range: RTDs can operate reliably across low and high temperatures, making them suitable for chemical reactors, gas compressors, and refinery equipment.
  • Pre-assembled and Factory-Calibrated: Ready-to-use designs simplify installation, minimize setup errors, and allow for faster deployment in industrial systems.
  • Seamless System Integration: Standardized output formats allow easy connection to PLCs, controllers, and monitoring systems, ensuring smooth data transmission.

2. Industry Applications

RTDs are widely used in critical industrial processes, including:

Chemical Industry

Monitoring reactor, storage tank, and pipeline temperatures ensures proper chemical reactions, maintains safety standards, and guarantees product quality.

Natural Gas Sector
