Accurate stress measurements in hydrogen environments
Among the new products on display from Sensors UK at the Sensors & Instrumentation exhibition will be what is thought to be the first gauge ever to be produced for accurate stress measurements in hydrogen environments while under high pressure.
>Strain gauges usually suffer from a high level of resistance change when used in hydrogen environments making accurate testing difficult. The new KFV gauge minimises this induced strain under pressure to 90Mpa for over 20 hours.
>The 350_ linear gauge has a special 2mm FeCr alloy foil and has a working temperatures of -30 to 80ºC while being as easy to install as general purpose gauges. Industries where this gauge is of particular importance include power and energy fields, and R&D for fuel cells and batteries.
