Inductive burst disc indicators for vacuum and back pressure protection
Inductive burst disc indicators specifically engineered for vacuum service and back pressure protection in industrial safety systems.
The rupture indicator for industrial plants at risk of counterpressure
In all those industrial plants where counterpressure risks exist, just as in those operating at low pressures, traditional rupture indicators often do not give satisfying results. To solve this issue, inductive rupture indicators are used, since they can signal the disc’s breakage even in such particular conditions.
DonadonSDD’s rupture indicators are not only functional at low pressures, but they also respect the standards of both ATEX and NAMUR environment directives, which makes them usable even in those applications and cases where explosion risks exist, in full respect of actual norms.
