Optic fibre rupture indicators
Managing instances of excessive pressure in industrial plants is a basic element of safety both for structures and technicians. Rupture discs are, as of today, the perfect tools to guarantee complete safety.
The rupture indicator for ultra-low pressures
In all those cases where it is necessary to signal the breakage of a rupture disc designed for ultra-low pressures, a significant difficulty often arises; the extremely reduced thicknesses and sizes of such discs make it impractical, or at times even impossible, to install any traditional kind of sensor, either for simple lack of space or because the material involved in a breakage would be of such small quantity that the signal would not activate.
To solve this issue, DonadonSDD has created a market exclusive with its unique optic fibre rupture indicators, specifically developed for the ultra-low pressures which we are specialists of. Optic fibre in these sensors makes it possible to signal breakage even with disc models designed for extremely low pressures, and thus extremely small and thin in construction – at any temperature, even the highest.
