Safety · Rupture Discs
Manufacturer: 
Optical rupture indicators Donadon OFI 04 and OFI 07 are very simple and reliable instruments for detecting bursting of discs. The terminals of the optical fibres are installed in the disc holder in a suitable position and are connected to an amplifier. Light transmission between the two optical fibres is interrupted by the bursting of the disc and a signal is sent to the plant’s safety system. If the amplifier is in an ATEX classified zone 1, 21, 2, 22, it must be installed inside an Ex d certified box. There are no electrical or moving parts in contact with the equipment to be controlled and therefore OFI indicators are not an ignition source.
