Pipe-Plug Thermistor Probes TH-44004-NPT-80 TH-44004-NPT-80
  • Ideal for Use in Pressure Vessel Applications 2500 PSI (172 Bar) Max.
  • Maximum Temperature 150°C (302°F) or 75°C (167°F) Depending on Option Selected.
  • 6mm Diameter Sheath with 1/4 or 1/8NPT Mounting Thread Standard Sheath and Plug are 300 Series Stainless Steel
  • 2 Meter (80") #26AWG Stranded, PFA Insulated and Jacketed, SST Braided Cable Standard (Other Lengths Available Upon Request)
  • Available in 5 Resistance Values and 2 Tolerances


These sensors are designed to be conveniently mounted directly into ports with 1/8NPT or 1/4NPT threads. The housings are machined from 300 Series Stainless Steel, contain a stainless steel strain relief spring, and stainless steel braided cables for use in rugged applications.

Sensor Specifications:
  • Maximum Temperature: 150°C or 75°C Depending on Accuracy
  • Housing: ¼ or 18 NPT with 6mm Diameter Tip
  • Cable: 2 meters of 2 Conductor, #26AWG Stranded, PFA Insulated and Jacketed, SST Braided Cable
  • Sensor Output: 2252Ω Standard, 3kΩ, 5kΩ, 10kΩ and 30kΩ Optional Resistances Also Available
  • Accuracy: ±0.2°C Standard, ±0.1°C Available


  • Note: The TH-44004-1/4NPT-80 model sensor replaces the original TH-44004-NPT-80 , the "1/4" before the NPT designation insures that you will get the correct mounting thread for your application.

    What is the dissipation constant of the TH-44004-1/4NPT-80-ROHS and in what medium does it apply to? I am acquiring thermistor data in LabVIEW and need to understand thermistor self-heating to choose an appropriate excitation current for my code.

    Is the jacketed cable and cable interface to the thermistor ingress rated for dust or water immersion?

    Asked by: Shutch
    Thank you for your inquiry. The jacketed cable is not ingress rated or for water immersion.

    What is the temperature resistance curve of the RTD?

    Asked by: datasheets
    The resistance curve is based on 2252 ohms at ambient. Here is the corresponding chart link (please see data under the 2252 curve): https://www.omega.co.uk/temperature/Z/pdf/z256-257.pdf
