Model Interpretation

3500 represents Bently Nevada standard machinery monitoring product family. /05 stands for system rack chassis component. Standard ordering suffix defines physical specifications: -01 for 14-slot full-size 19-inch rack, -02 for 7-slot compact 12-inch rack; mounting options include panel mount, standard rack mount and bulkhead mount available only for full-size version.

Technical Parameters

Mechanical Specification

Full-size chassis follows 19-inch EIA standard with total 14 module slots, compact type adopts 12-inch dimension with 7 available slots. Full-size dimension is 132.1mm × 482.6mm × 330mm, compact size is 132.1mm × 304.8mm × 330mm. Rugged coated steel construction improves mechanical rigidity against vibration and corrosion. Total unit weight is approximately 7.5kg. Three installation selections cover panel, standard cabinet rack and bulkhead mounting.

Backplane and Power Distribution

Internal proprietary backplane realizes inter-module high-speed digital communication and regulated power routing. System operating power originates from externally installed power supply modules with nominal 24VDC input requirement. First two leftmost positions are fixed for power supply module and system interface module respectively, remaining slots reserve for various monitoring and signal conditioning modules.

Environmental Rating

Operating ambient temperature ranges from -20°C to +60°C, storage temperature covers -40°C to +70°C. Designed to meet IEC 60068 anti-shock and anti-vibration criteria for field installation. Certified with UL, CE and CSA industrial safety approvals.

Core Functions

Offer standardized mechanical housing to assemble all compatible 3500 series functional modules for flexible system configuration expansion. Built-in backplane enables seamless internal data communication between inserted modules without extra interconnection wiring. Distribute stabilized operating power to every loaded module uniformly via internal conductive traces. Robust metal casing provides effective EMI shielding and physical protection against dust and mechanical impact. Support convenient module hot swap and incremental system expansion by adding monitoring cards on vacant slots.

Applications

Deployed on gas turbine, steam turbine and generator units inside thermal and hydroelectric power plants. Applied for centrifugal compressor, large pump and blower monitoring within oil, gas and petrochemical facilities. Used for critical motor, gearbox and rotating equipment protection in metallurgy and heavy processing industries. Suitable for onshore and offshore process plant rotating machinery condition supervision.

Usage & Maintenance

Complete rack fixation with selected mounting method first, then install power module at slot one and interface module at slot two before inserting other monitoring modules sequentially. Complete rear terminal wiring for field sensors, external power and system communication circuits. Perform regular annual inspection of backplane connectors and internal cleanliness. Fanless chassis structure eliminates periodic fan maintenance work. Product remains active with full official spare part supply from Baker Hughes Bently Nevada.
