Rembe introduces NIMU (Non-Invasive Monitoring Unit), a non-invasive rupture disc monitoring unit that provides information about the way a bursting disc responds to positive and negative pressure. NIMU is installed in a blind tapping in the outlet section of the rupture disc holder, thus isolating it from the process medium. The signaling method is particularly suited for critical processes and applications that require the entire system to be completely impermeable. NIMU is a reusable monitoring system. After a rupture disc has opened, only the rupture disc itself must be replaced. If NIMU need to be serviced or replaced, this can be done without opening the pipeline.
NIMU is based on intrinsically safe, closed circuit technology so it can be easily integrated into an existing process control system, using terminal boxes and isolating amplifiers, according to Rembe. It meets all certification and zoning requirements.
