A Threaded Compression Fitting Thermocouple is a sheathed temperature sensor with an adjustable compression fitting for secure installation and flexible probe insertion depth. It is designed for pipelines, boilers, furnaces, vessels, ovens, and other equipment requiring stable insertion or immersion temperature measurement.

The compression fitting locks the armored probe in position after adjustment, providing reliable mounting and sealing. K, J, T, E, and N types are available with Φ3–8 mm probes, SS304, SS316, or Inconel 600 sheaths, and metric or pipe thread options.

This design is part of our Sheathed Thermocouple series and is particularly suitable when the probe insertion depth needs to be adjusted during installation.

Key Features

• Adjustable probe depth: Slide the probe to the required insertion depth before tightening the compression fitting.
• Threaded mounting: Provides secure installation on pipelines, equipment chambers, vessels, and other industrial equipment.
• Stable probe fixation: The fitting clamps the probe securely after adjustment.
• Armored construction: The sheathed probe provides mechanical protection, flexibility, and fast temperature response.
• Flexible measurement: Suitable for insertion and immersion temperature measurement in industrial processes.
• Custom configurations: Probe diameter, length, sheath material, thread, junction, and connector can be customized.

Thermocouple Types

K, J, T, E, and N thermocouple types are available for different temperature measurement requirements. For help comparing thermocouple types, see our Thermocouple Types Selection Guide.

S-Type, R-Type, and B-Type configurations are available for special high-temperature applications. Actual temperature capability depends on thermocouple type, sheath material, probe diameter, installation, and operating conditions.
