Product Introduction
The Bently Nevada 3500/05-01-02-05-00-01 is a primary rack assembly for the 3500 series machinery protection system. It is part of a modular, high-reliability continuous monitoring platform designed for critical rotating machinery such as large turbines, compressors, and generators. This rack provides the physical enclosure, power distribution, and communication backplane for up to 16 monitoring modules.
The part number configuration indicates:
3500/05 – Rack assembly (mainframe)
01 – Standard full-size rack (19-inch)
02 – Universal AC power supply (85–264 VAC, 47–63 Hz)
05 – Power supply input with conformal coating and high-voltage transient protection
00 – No internal transducers or special modifications
01 – Standard slot configuration (full complement of I/O module slots)
The rack includes two power supply slots (redundant configuration), one keyphasor module slot, and up to 14 slots for monitoring modules (proximitor, velocity, acceleration, temperature, etc.). The backplane supports internal module communication, serial data interfaces, and relay output connectivity. All modules are hot-swappable.

Application Scenarios
The 3500 rack is used exclusively for critical machinery protection and continuous monitoring in industries where unplanned shutdown results in high safety or financial risk. Typical applications include:
Steam and gas turbines – Power generation plants (utility and industrial), combined cycle facilities, and marine propulsion systems. Monitors radial vibration, axial position, eccentricity, and case expansion.
Centrifugal and axial compressors – Oil & gas refineries, natural gas transmission, petrochemical plants, and LNG facilities. Detects surge conditions, rubs, and bearing wear.
Large electric generators – Nuclear, thermal, and hydroelectric power stations. Monitors air gap, rotor vibration, bearing temperatures, and rotational speed.
Large pumps (boiler feed, main cooling water) – Power stations and water treatment plants requiring high availability. Provides 4–20 mA outputs to plant DCS/PLC systems.
Fans and blowers (critical duty) – Induced draft (ID) fans, forced draft (FD) fans in cement, steel, and paper mills.
Keyphasor reference – Used with a 3500/25 or 3500/77 keyphasor module to provide once-per-turn timing signals for phase measurement, orbit displays, and rotor balancing.
