Statox 501 HRC and ARE – The detectors for flammable gases
Heat tint sensors detect all flammable substances – even if not with the same sensitivity:
For short-chain alkanes, the HRC sensor is typically used – for molecules with 1 to 4 carbon atoms, such as methane CH4, ethane C2H6, propane C3H8, or n-butane C4H10.
The measurement of highly volatile substances (such as fuels or solvents), on the other hand, is the strength of the ARE measuring head.
As neither system has its own display or relay, this system must be operated with the Statox 503 control module. Together, functional safety up to SIL2 can be achieved.
