The Omega TH-44000-NPT is a reliable thermistor probe designed for direct insertion into pipes and process lines via a standard NPT fitting. Engineered for accurate and fast temperature sensing in fluid systems, this probe integrates cleanly into your setup—no custom mounting brackets or housings needed.
With its sealed construction and robust stainless steel overbraiding, this thermistor probe is ideal for use in HVAC, compressed air systems, chillers, boilers, and process loops. It maintains consistent performance under dynamic temperature swings while protecting the sensing element from moisture, vibration, or particulate ingress.
Because it threads directly into the system via the NPT threads, the sensor simplifies new installations and/or retrofitting existing installations. The TH-44000-NPT gets you a compact, dependable thermistor probe that delivers precise data with minimal setup. With durability and speed built in, it’s a great fit for engineers needing high-fidelity feedback in control loops or monitoring systems.
Omega’s reputation for precision and long-term stability means you can trust this thermistor probe to perform over its lifetime—one part to install, one component to maintain, and one reliable data source to guide your control decisions.

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.
Hi Samanthaarato,
Thank you for the inquiry. Link to operating current and heat dissipation values;
