Overview
The Thermocouple Without Fixed Fitting is a simple, adaptable temperature sensor designed for maximum flexibility in installation and application. Unlike conventional thermocouples with threaded fittings, flanges, or bayonet mounts, this version comes without any fixed mechanical mounting hardware—making it ideal for temporary setups, tight spaces, or user-defined installation scenarios.
It offers all the core benefits of standard thermocouples—accurate, fast-response temperature measurement—with the added advantage of unrestricted positioning and integration.
Structure & Working Principle
This type of thermocouple typically includes:
- Sensing Element: A thermocouple wire pair (e.g., Type K, J, T, etc.) encapsulated in insulation.
- Protective Sheath (optional): Often a stainless steel or metal tube for mechanical protection (armored version).
- Flexible Lead Wires: Allow connection to temperature controllers, meters, or data loggers.
Since it has no built-in mounting system, the thermocouple can be inserted directly into holes, gaps, or sleeves, or secured using custom clamps or brackets, giving users complete control over placement.
Key Features
- No Fixed Mounting: Fully adaptable for user-defined installation. Perfect for environments where mounting hardware cannot be pre-installed.
- Simplified Design: Minimalist structure makes it lightweight, easy to transport, and quick to deploy.
- Fast Response Time: Sensitive measurement tip ensures quick detection of temperature changes.
- Cost-Effective: Lower production and material cost compared to thermocouples with custom fittings or welded structures.
- Customizable: Probe diameter, length, insulation material, and lead wire type can all be tailored to your specifications.
Typical Applications
- Laboratory experiments
- Prototype and temporary equipment testing
- Field temperature monitoring
- Compact devices or systems with limited space
- Maintenance and troubleshooting tasks
