Features:

• 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

Features:

• 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

Features:

• 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
