Threaded Assembly Thermocouple
Threaded Assembly Thermocouple is a fixed-thread temperature sensor for industrial equipment, pipelines, furnaces, ovens, and vessels. Its fixed threaded mounting structure holds the sheathed probe securely for stable temperature measurement.
EaseWise supplies K, J, T, E, and N types with SS304, SS316, or Inconel 600 sheaths. Probe diameter, insertion length, thread, connector, and cable length can be customized for OEM and replacement applications.
Choosing between an assembly and sheathed thermocouple? See our Sheathed vs Assembly Thermocouple guide to compare construction, installation, response time, protection, and typical industrial applications.
Threaded Thermocouple Features
- Fixed threaded assembly: Provides secure and vibration-resistant installation.
- Fixed insertion depth: Prevents probe movement during operation.
- Industrial mounting: Suitable for pipelines, furnaces, ovens, vessels, and machinery.
- Sheathed probe: Provides mechanical strength and reliable temperature measurement.
- OEM flexibility: Custom probe length, thread, connector, and L-type configuration are available.
Threaded Assembly Configuration
| Configuration | Description | Typical Use |
|---|---|---|
| Fixed Thread Mount | Probe and threaded base are fixed together | Pipelines, furnaces, ovens, industrial equipment |
| Straight Probe | Straight sheathed probe for direct insertion | General industrial temperature measurement |
| L-Type Probe | 90° right-angle probe available by custom order | Limited installation space |
Thermocouple Type Selection
For help comparing different thermocouple types, see our thermocouple selection guide.
| Type | Temperature Range | Typical Applications |
|---|---|---|
| Type K | -200°C to 1260°C | Furnaces, machinery, general industrial measurement |
| Type J | -40°C to 750°C | Machinery, ovens, plastic processing |
| Type T | -200°C to 350°C | Low-temperature measurement |
| Type E | -200°C to 800°C | Testing and laboratory equipment |
| Type N | -200°C to 1300°C | High-temperature industrial equipment |
Actual operating temperature depends on thermocouple type, sheath material, probe diameter, atmosphere, installation conditions, and required service life. S/R/B types are available by custom order.

Fixed vs Adjustable Threaded Thermocouple
This Threaded Assembly Thermocouple uses a fixed insertion depth and is suitable when the installation position is predetermined and stable.
For applications requiring adjustable probe insertion depth, the Threaded Compression Fitting Thermocouple provides adjustable probe positioning before the compression fitting is tightened.
