BENTLY NEVADA 3500/42M-09-00 Earthquake Monitoring Module

Product Description

Bently Nevada 3500/42M-09-00 is a 4-channel Proximitor / Seismic Monitor module for Bently Nevada 3500 Machinery Protection TSI system, the core card of rotating machinery protection system. This module accepts signals from eddy-current proximitors and seismic velocity / acceleration transducers. The four channels are independently programmable to measure radial vibration, thrust position, differential expansion, eccentricity, vibration velocity, acceleration and more. It provides programmable alarm and trip outputs. Compliant with API670 and IEC61508 SIL2. It is mounted in the 19-inch rack of the 3500 system. Widely used for online condition monitoring and protection of steam turbines, compressors and other critical rotating equipment, it is a common spare part for TSI systems in power, oil & gas and chemical industries.
