Innovation in Hydrogen‑Production Temperature Measurement: Field Application of Endress+Hauser iTHERM SurfaceLine TM611 Non‑Invasive Temperature‑Measurement Solution

Hydrogen‑production facilities put forward extremely strict safety requirements for process temperature measurement. Conventional invasive temperature sensors require thermowell penetration into hydrogen pipelines, which brings hidden dangers such as hydrogen leakage, hydrogen embrittlement risk, flow turbulence and high‑cost shutdown modification. Endress+Hauser’s iTHERM SurfaceLine TM611 clamp‑on non‑invasive temperature‑measurement solution has achieved stable field operation in multiple hydrogen‑production projects, bringing a new safe measuring path for green hydrogen and industrial hydrogen‑making plants. As a professional B2B industrial instrumentation platform focusing on new‑energy process industries, Intellprime shares real‑world application progress of hydrogen‑related measuring instruments for global buyers.

The iTHERM SurfaceLine TM611 is externally clamped onto the outer wall of hydrogen‑process pipes. No drilling, welding or process shutdown is needed for installation. Its optimized thermal‑coupling structure delivers measurement accuracy and response performance comparable to traditional inserted RTD sensors. The measuring range covers ‑196 °C to 400 °C, covering low‑temperature pre‑treatment, high‑temperature reforming and other core working conditions across hydrogen‑production workflows.

In hydrogen‑production field applications, the biggest advantage of this non‑invasive solution is eliminating pipeline penetration points. It fundamentally avoids hydrogen leakage risks caused by thermowell weld defects and hydrogen‑induced material embrittlement. Whether for new green‑hydrogen project construction or temperature‑point retrofitting of existing electrolyzer and reformer units, the TM611 can be deployed without stopping production, cutting reconstruction cost and production‑halt losses significantly. It also reduces pressure drop and flow disturbance inside hydrogen pipelines, helping optimize overall system energy efficiency.

The instrument supports hazardous‑area explosion‑proof certification, adapting to Classified zones in hydrogen‑generation workshops. Collected temperature data can be seamlessly connected to DCS control systems, supporting stable monitoring for electrolysis water hydrogen production, steam methane reforming and other mainstream hydrogen‑making processes.
