Product Description
A bare wire thermocouple is a basic temperature sensing element. It consists of two metal wires of different materials welded together at one end to form the measuring junction (hot junction), while the other end (cold junction) remains exposed for connection to measuring instruments. This simple design makes it a highly flexible and cost-effective temperature measurement solution, usable directly as a sensor or integrated as a core component into more complex temperature probes.
Key Features
Uninsulated Design, Extremely Fast Response: Because its measuring junction is directly exposed to the environment, bare wire thermocouples can react rapidly to temperature changes, making them particularly suitable for dynamic measurement scenarios requiring the capture of instantaneous temperature fluctuations.
Can Be Used as a Core Component: It is the fundamental core component for constructing more complex "ceramic bead insulated thermocouples" or "mineral insulated (MI) armored thermocouples."
Main Applications and Scenarios:
Industrial Furnaces and High-Temperature Process Monitoring: In industries such as steel, metallurgy, and glass, bare wire thermocouples made of precious metals such as platinum and rhodium can be directly inserted into high-temperature furnaces for accurate measurements. SAB and MESUREX products are specifically designed for these environments.
Laboratory R&D and Testing: Researchers often need to build their own sensors when setting up test benches or conducting materials testing. Bare-wire thermocouples are ideal for laboratories due to their flexibility.
OEM Equipment Integration: Equipment manufacturers can embed bare-wire thermocouples as components into plastics machinery, packaging equipment, HVAC systems, etc., to monitor the temperature of critical components.
Automotive and Aerospace Testing: Used for monitoring engine exhaust systems, brake disc surface temperatures, or performing extreme tests such as battery puncture, their rapid response and high accuracy are crucial in these scenarios.
