RDI-S - Burst Sensors & Indicators


Burst Indication for use in Sanitary Tri Clamp Fittings


  • One time use, LOW COST
  • 25mm (1”) to 100mm (4”) diameter
  • Early indication of burst minimizes product waste and environmental damage from release of harmful process fluids
  • Supplied ready for installation
  • Fits standard Tri Clover and NA couplings used with sanitary ferrules to BS48251
  • Burst is detected by breakage of silver conductor element printed to the chemically resistant polymide detector membrane. Signal may be used to activate a variety of alarm or control equipment
  • Signals instantly when the bursting disk ruptures
  • Unique alignment pin design ensures proper disk orientation into RAH holder
  • The RDI-S sensor has been ATEX system certified to ATEX directive 94/9/EC and standard EN500392


The RDI-S installs onto the vent side of a sanitary bursting disk assembly. Upon rupture of the disk, the RDI-S alarm circuit is opened by the flowing media.

  • One-time use, low cost design compatible with metal or graphite bursting disks
  • Fits easily into existing piping systems
  • Installs on the outlet side of bursting disk or bursting disk holder, isolating the RDI-S from the process media
