Benefits
User-friendly and reliable from product selection to maintenance
iTHERM inserts: globally unique, automated production. Full traceability and consistently high product quality for reliable measured values
iTHERM QuickSens: fastest response times 1.5 s for optimum process control
Since the temperature of compressed hydrogen increases with expansion during filling, temperature measurement is essential at hydrogen filling stations for safety reasons.
Our non-invasive thermometer can be easily retrofitted to the existing pipe and integrated into the control system to enable efficient stand-by operation of a turboset.
The Ziegler-Natta process uses hazardous chemicals like titanium tetrachloride. Precise temperature measurement is crucial to prevent runaway reactions and ensure safety and efficiency.
