BI - Burst Sensors & Indicators


The BI Series integral burst indication offers a simple and effective means of indication over-pressure or discharge indication for rupture disk (bursting disc) applications.


  • Less affected by back pressure from common discharge manifolds
  • Compatible with most ZOOK flat-seat metal and sanitary rupture disks
  • Classified as a simple apparatus and may be used in a hazardous environment. Must be used in conjunction with intrinsically safe certified electrical apparatus and installed & maintained to meet all other requirements of an intrinsically safe installation & local codes
  • Cost effective against traditional remote membrane type detectors, especially in larger sizes
  • Reduces stock inventory by incorporating the burst indicator and disk into a single unit
  • BI comes standard with connection 2 and 6’ (1828 mm) of signal wire if not specified
