Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 

The Continental Disc Corporation BDI-FLX is a burst disc indicator system powered from an intrinsically safe interface (with galvanic isolation or from a zener barrier) for location in zone 0 or zone 20 hazardous areas. The burst disc indicator includes a resistive sensor element which changes resistance in response to bending, and therefore provides warning of the rupture disc's burst. An interface unit mounted in close proximity to the sensor converts the sensor signal into a signal to be interpreted by a switch amplifier or similar device in the non-hazardous area.

 

Intrinsic safety Parameters:

Ui = 12 V dc
li = 60 mA
Pi = 180 mW
Ci = 1.11µF
Li = 0

 
CONDITIONS OF CERTIFICATION: YES as shown below:
 

Temperature Class of the BDI-FLX sensor is marked as Tx, since the surface temperature is controlled by the process temperature being monitored. The sensor itself exhibits negligable temperature rise.

 

When located in an area requiring EPL Ga (e.g. a Zone 0 hazardous area), the user shall ensure that electrostatic charging of the interface enclosure cannot occur.

 

When located in an area requiring EPL Gb or Gc (e.g Zone 1 or Zone 2), the interface enclosure represents an electrostatic hazard and the enclosure shall only be cleaned using a damp cloth. Solvents shall not be used.
