 ZOOK Burst Sensors & Alarm Monitoring


BA Rupture Disk Burst Sensor



  • Electrically conductive

  • Mounts between two support rings insulated from piping

  • Installs on vent side of the disk holder

  • Requires minimal space (less than 1/8" thick, including gaskets)

  • Adapts to virtually all makes/types of rupture disks, including graphite types

  • Fits easily into existing pipe systems

  • Reusable and replaceable

  • Optional leak detection for damaged rupture disks or fugitive emissions from relief valves or atmospheric designed systems


ZENSOR Rupture Disk Burst Sensor


  • Rugged design withstands rough handling and severe service conditions

  • Rupture disks and tantalum sensing element are PTFE-coated for maximum corrosion resistance

  • Rupture disk and sensing element are integral parts of the electrical circuit to eliminate false readings

  • Sensing element mounts on the vent side of the disk

  • Shipped complete, including gaskets, ready for easy installation


ZM2 Rupture Disk Alarm Monitor



  • Factory Mutual approved as having intrinsically safe output for Class I, II, and III, Division 1, Groups A, B, C, D, E, F, and G hazardous locations

  • Factory configured for latching operation and 115 VAC.  Each channel can be independently changed to non-latching

  • Failsafe design

  • Enclosure:  NEMA Type 12, constructed of 14 gauge steel with continuously welded seams and oil resistant seals

  • Provides audio and visual signals for each channel, with output relays

  • Contains front panel push buttons for testing and resetting each channel.  This function can also be performed remotely

  • Field replaceable sense module

  • Dimensions:  11 1/2" H 8 1/4" W 4" D

  • Intrinsically safe sensing signal level:  6 VDC @ 7.5 mA max.

  • Operating voltage:  115/230 VAC @ 50/60 Hz; 12 VDC

  • Monitor sensing level:  Open (ruptured) 200 ohm or greater

  • Output relay contacts:  1 normally open and 1 normally closed for each channel rated 3 amps, 120 VAC (resistive)

  • Operating temperature:  -15F to 140F
