NIMU Signalling Unit

NIMU is a reusable, non-invasive detection system. 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. The days when the signalling cables also had
to be routed again to the respective switching box are finally over.
