Electric burst disc indicators for hazardous industrial environments
Versatile electric burst disc indicators installable after disc mounting, certified ATEX and IECEx for use in explosive or fire-risk environments.
The rupture disc sensor which can be implemented at any time
The base model for rupture disc sensors, electric indicators present the advantage of being suitable for mounting at any time, even after installation of the disc they must monitor – a unique benefit among rupture indicators. This is due to their being a distinct, separate unit, which only needs a simple electrical connection.
DonadonSDD adds heightened performance, and the possibilty of functioning even at low pressures, high temperatures, and under ATEX and IECEX certifications, to the traditional simplicity and reliability of this classical model of indicator. We also offer a special model capable of notifying not just the disc’s rupture, but the leakages which often come before it, allowing for timely pre-emptive intervention.
