What is a rupture indicator? How Does a rupture indicator Work?

A rupture indicator, also known as a burst or pressure safety disc indicator, is a device used in conjunction with DonadonSDD products in industrial settings.

The rupture indicator serves as a monitoring system for safety discs or venting panels. It is designed to provide immediate notification when the device has been activated (i.e., the disc burst due to excessive pressure). This is typically done through generating an electrical signal, which can then trigger various types of alerts such as setting off a siren, illuminating a visual alarm, sending a notification to a control system, or even initiating a shutdown of the entire plant, depending on the system’s design.

Rupture indicators are crucial in large industrial facilities where continuous manual monitoring of all rupture discs may not be feasible. By providing real-time alerts, they enable swift identification of the location and nature of pressure-related issues, thus allowing for immediate corrective action and minimizing potential damage or downtime.

Why choose DonadonSDD rupture indicators for your industrial safety needs?

DonadonSDD offers a broad selection of rupture indicators to meet the diverse needs of our customers. We understand that different industrial settings may require different types of monitoring systems, and we’ve got you covered:

ELECTRIC: This is the classic model that can be installed even after the disc has been put in place. It’s an adaptable and versatile solution suitable for a wide range of applications. Our electric rupture indicators come with ATEX and IECEX certifications, ensuring compliance with strict international safety standards. This makes them suitable for use in environments with a high risk of explosion or fire, providing an added layer of safety.
MAGNETIC: Our magnetic rupture indicators are designed to be mounted externally, making them reusable. This can be a cost-effective choice for many facilities.
INDUCTIVE: We’ve specifically developed these rupture indicators for vacuum or back pressure protection.
OPTIC FIBRE: These rupture indicators are created to work even with ultra-low pressure rupture discs.

By choosing DonadonSDD rupture indicators, you’re opting for a solution that combines ease of use, high performance, certified safety, and advanced warning capabilities, providing an optimal solution for your industrial safety needs.
