Bursting Disk Equipment
with integrated alarms / special solutions
Bursting disk equipment with integrated alarms can be of diverse design. Either an inductive proximity switch is used that works in combination with other metal flags on the burst membrane, or the conductor path to be destroyed is directly integrated in the bursting disc, so that the amount of components can be further reduced. Special solutions such as extruder bursting discs with integrated breakage monitoring round off the STRIKO offer.

Special solutions –
extruder bursting disks
Also extruder bursting diks can be equipped with integrated breakage monitoring. For this purpose the discharge side of the bursting disc body is equipped with shear plugs. Through a precisely fitting hole, the closed circuit current carrying cable is laid which will be cut when the bursting disc opens and associated material comes out. The closed circuit current is thus interrupted and the desired signal activated.
Special solutions –
in bursting disks with integrated alarm
For this variant of the breakage monitoring, the closed circuit current conductor path is directly integrated in the burst disc unit. This design can be implemented for all metal bursting disks. However, since the manufacture is very time consuming, it can only be used in special applications. Simple ask our specialists – we look forward to advise you.
Note about ATEX
According to notification 3.42-10333/98-El of the National Metrology Institute (PTB) of 07/01/1998 the alarm represents, in terms of the ignition protection type own safety “i”, a so called simple electrical operating material, and is described in detail in Section 5.4 from EN 50020. Simple electrical operating materials must not be certified, if they meet the requirements from EN 50020 and Section 6.1.3.1.3 from DIN VDE 0165/1991-02 “Establishing an electrical system in explosive areas”. All STRIKO alarms meet these requirements.
