A new non-invasive signaling device for rupture discs
The NIMU (photo) is the latest non-invasive signaling device for rupture discs. Conventional signaling devices require cables to be mounted on the rupture disc, which must then be routed out through the rupture disc holder. Conversely, with the NIMU, a signal indicator is attached to the rupture disc during the manufacturing process. The actual sensor is screwed into a blind tapping in the rupture disc holder, where it monitors the position of the signal indicator on the rupture disc. This means that the wiring only starts outside the rupture disc holder. After an overpressure event, and the associated opening of the rupture disc, the outlet part of the rupture disc holder must be removed, the rupture disc replaced, and afterwards the system can be put back into operation.
