The  Bently Nevada 3500 Series Internal Barrier Modules are intrinsically safe interfaces that provide explosion protection for transducer systems connected directly to the 3500 Machinery Protection System.

The barrier designs are fully compatible with the 3500 System, and provide a convenient and cost-effective solution for installing all types of transducer systems within a hazardous area. Unlike external barriers, 3500 Internal Barriers are an integral part of the 3500 System and will not degrade the 3500 System’s performance.

Standard and Internal Barrier monitors can reside within the same 3500 rack, which increases the overall flexibility of the 3500 system. Users can upgrade standard monitors to those that contain internal barriers by replacing existing I/O modules.
