Bently Nevada ADRE 408 DSPi Condition Monitor

Portable multi-channel machinery DAQ built for rotating-equipment diagnostics — up to 32 simultaneous channels, synchronous/asynchronous sampling, Keyphasor speed inputs, and ADRE Sxp software for real-time plots and stand-alone store.

Key advantages

Up to 32 channels — Four sampling-card slots; each 8-channel dynamic card uses 24-bit ADCs with simultaneous sync across the chassis.
Machinery-native processing — Direct/bandpass amplitude, 1X/2X and user nX vectors, gap/bias, orbits, Bode/polar, spectra, and structural/impact support.
Keyphasor / speed cards — Up to two 3-channel speed/trigger cards (6 physical + 6 simulated speed inputs) for order tracking and sync sampling.
Field or test-stand portable — Stand-alone store on internal SSD (480 or 960 GB options); dual Gigabit Ethernet; front-panel sample/trigger without a client PC.
ADRE Sxp ecosystem — Quick Configuration software, 3500 rack importer, digital replay card option, and viewer-license tiers.

Typical applications

On-site turbomachinery diagnostics and acceptance tests.
Test-stand multi-channel vibration and process-variable capture.
Balancing and startup/coast-down with Keyphasor-synchronous data.
Structural/impact transfer-function work with force-hammer kits.
Remote or multi-client viewing across LAN/WAN with ADRE Sxp.

Selection guide

Card mix — Count of 8-ch dynamic (168905), 3-ch speed/trigger (168906), transducer power (168908), and slot-5 digital replay (168907).
Storage / power — 480 vs 960 GB SSD; AC power-supply cord set; hard case or 19 in rack kit.
Software licenses — Full client vs Network Viewer vs Archive Viewer quantity; Quick Configuration included with full clients.
Accessories — Impact hammer kit, laser Keyphasor adapters, field wiring harnesses for transducer power.

Common mistakes

Ordering dynamic cards only when the job needs Keyphasor sync — budget at least one speed/trigger card for shaft-referenced work.
Assuming transducer power is built into every slot — ICP/±24 V power may need the 168908 card and harnesses.
Buying Archive Viewer when live control of a 408 is required — that tier cannot connect to the instrument.
Blocking fan inlets or using the unit outdoors in condensing spray — OEM rates indoor/outdoor instrument care, not wash-down exposure.

FAQ

Q: How many channels can one 408 DSPi run? A: Up to 32 dynamic channels with four 8-channel sampling cards; speed/trigger cards share those slots.

Q: Does it need a PC to collect data? A: No — it can store stand-alone; ADRE Sxp clients connect over Ethernet for configuration and live plots.

Q: What should I send for a quote? A: Card mix, SSD size, power-cord region, software licenses, accessories, quantity, ship-to.
