Supported Applications
The Omega TC-(*)-NPT Series consists of rugged pipe plug thermocouple probes designed for vessel applications, pressurized chambers, and pipelines. These sensors provide temperature measurement in environments requiring a threaded mounting interface.
Operating Conditions & Performance
The series supports process temperatures up to 650°C (1200°F). The transition joint and cable are rated for temperatures up to 480°C (900°F). Probes withstand pressures of 2500 psi at ambient temperatures. Accuracy meets or exceeds Special Limit of Error (SLE) per EN 60584-2: Tolerance Class 1.
Key Performance Specifications
- Process Temperature: To 650°C (1200°F)
- Cable/Transition Joint Temperature: To 480°C (900°F)
- Pressure Rating: 2500 psi at ambient temperatures
- Accuracy Class: Meets or exceeds Special Limit of Error (SLE) per EN 60584-2: Tolerance Class 1
Configuration Options
The TC-NPT series is configurable across multiple parameters to suit specific installation requirements. The probes feature a 304 Stainless Steel housing and sheath with an integrated stainless steel strain relief spring.
Sensor Elements & Junction Types
- Thermocouple Calibrations: Type J, K, T, or E
- Junction Configurations: Grounded (G), Exposed (E), or Ungrounded (U)
- Element Count: Single element or dual element configurations are available.
Mounting & Connections
- Process Threads: ¼ NPT or ⅛ NPT mounting threads
- Electrical Connection: Stripped leads standard; SMPW connectors optional.
- Lead Wire Construction: Stainless steel braid over fiberglass, stranded wire (20 AWG for ¼ NPT models; 24 AWG for ⅛ NPT models).
Customization & Options
Beyond standard configurations, the series supports special custom designs including different NPT threads, tip diameters, and tip lengths. A flush tip option is available upon consultation with engineering.
- SMPW Connectors: Optional for specific models.
- Lead Lengths: Standard length provided; additional price per 300 mm (12") increments applies for lengths over 2 m (80").
Key Product Differences
Variants within the TC-NPT series are distinguished by their calibration type, junction configuration, thread size, and element count. Model numbers follow the format TC-(*)-NPT-(**)-72, where (*) specifies the calibration (J, K, T, or E) and (**) specifies the junction type (G for Grounded, E for Exposed, U for Ungrounded).
Dual element probes are identified by a "DUAL" suffix in the model number. Models with optional SMPW connectors include an "SMP" designation. The series offers specific dimensional variations based on thread size: ¼ NPT models feature a 14 HEX (0.75") and a stainless steel strain relief spring of 64 mm (2.5"); ⅛ NPT models feature an 11 HEX (0.56") with a spring length of 60 mm (2.38"). Both thread sizes share a probe diameter of 9.6 Dia. (0.38).

Works As Intended
Good product, decent quality, worked well for our plug and play application - we used this to measure oil temperature inside the shock absorbers.

Best fitting based thermocouple
Great process thermocouple, good strain relief, not too long exposed end. Overall easy to install and use.

It's a thermocouple.
Exactly what it looks like. Works as expected. If only the cable diameter was listed in the product specifications.
