RDI - Burst Sensors & Indicators


The Rupture Disk (bursting disc) Indicator or RDI Series is a simple and effective means of indicating when the process media ruptures a disk or opens a safety relief valve.


  • One time use, cost effective, stand alone burst indication
  • Compatible with Metal or Graphite Rupture Disks or for stand alone use (relief valve applications)
  • Resistant to most chemicals
  • Minimizes downtime due to immediate burst indication
  • Supplied ready for installation
  • Installs easily into existing pipe systems
  • Furnished with attached 6’6” (2m) PTFE sheathed connection cable
  • No routine maintenance required
  • Installs on outlet side of rupture disk or rupture disk holder isolating the RDI from the process media
  • RDI is considered a simple device, therefore ATEX approval is not required. Installation must be in accordance with ANSI/ISA RP12.6 and the NEC (ANSI/NFPA 70)
