  • Alarm system for graphite safety disk

    Accueil » Protection against pressure and vacuum » Bursting discs » Graphite discs
    Detection with Two tantalum contacts

    Detection with contact finger
    		 Description :

    The alarm systems used for monitoring graphite safety discs provide a visual and acoustic alarm or trigger plant cutoffs. Two tantalum contacts or a contact finger in the alarm system press against the membrane of the safety disc and close the circuit of an amplifier relay. When the safety disc ruptures, the current circuit is interrupted and this triggers the alarm.

    Advantages :

    • Corrosion resistance ensured by use of suitable materials
    • Reusability after safety disk rupture
    • Simple electrical connection via the 1.5 meter-long integral connecting cable
    • Used together with the matching amplifier relay, this system can also be operated in high explosion risk zones

    Technical data :

    • Service voltage : AC 207V-253V, 45Hz – 60Hz, DC20 V – 30V
    • Circuit [EExia] II C, input as per DIN 19234 (Namur)
    • Output: 1 changeover AC 253 V / 2 A, DC 40 V / 2 A
    • The amplifier relay should be mounted outside the explosion risk zone

  • Bursting disc N – for universal use

    Accueil » Protection against pressure and vacuum » Bursting discs » Graphite discs
    Application : Standard applications with partial vacuum

    Construction :

    • Monoblock construction for direct mounting between DIN / ISO or ANSI standard flanges
    • Fragmenting disc
    • Synthetic resin-impregnated process equipment graphite

    Field of use :

    • Bursting pressure : 100 mbar to 80 bar
      • N I : 0,1 to 50 bar
      • N II : up to 80 bar
    • Maxi service pressure in % of nominal bursting pressure :
      • Static load : 75%
      • Oscillating load : 70%
    • No change in bursting pressures from -60 to +50°C, thereafter about 5% reduction per 40°C rise in temperature

    Some other type of bursting discs (stainless steel, nickel, inconel, graphite…) may reach your need, feel free to contact us.
