Description
Bently Nevada 1900/65A-00-00-01-00-00 General Purpose Equipment Monitor – Compact Machinery Protection for Pumps, Fans, and Motors
The Bently Nevada 1900/65A is a standalone general-purpose equipment monitor designed for continuous vibration and speed monitoring on non-critical or essential rotating assets. From my experience, it fits best on pumps, blowers, small compressors, gearboxes, and electric motors where you want reliable protection and simple 4–20 mA/relay interfaces to a DCS or PLC—without the complexity of a full rack system. One thing I appreciate is how flexible it is with sensors: proximitor systems, accelerometers, and velocity pickups are typically supported, so you can standardize across different machines.
Company’s Order Placement Process and Guarantees
- Warranty period: 365 days
- Delivery: 1 week for in-stock; no more than one month at the latest
- Payment: 50% advance payment; full payment before delivery
- Express options: FedEx, UPS, DHL
Key Features
- Two-channel vibration + speed (typical 1900/65A build) – Covers radial vibration on bearings and a Keyphasor/speed input for alarm logic and trending.
- Universal sensor compatibility – Works with proximity probes (shaft vibration/position), industrial accelerometers, and velocity sensors on fans, motors, and pumps.
- Industrial outputs for easy integration – 4–20 mA proportional outputs and configurable alarm relays to tie in with PLC/DCS safety or interlocks.
- Modbus connectivity – RS‑485 Modbus RTU is commonly used for remote values and status in SCADA systems.
- Buffered signal access – Buffered BNCs for portable analyzers, making on-site diagnostics fast without rewiring.
- DIN-rail friendly footprint – Fits neatly in compact panels, which is great on skid packages and MCC rooms where space is tight.
- Field-proven protection logic – Standard alert/danger alarms and voting schemes aligned with common industry practice for condition monitoring.
Note on this configuration: 1900/65A-00-00-01-00-00 appears to be a standard general‑purpose option set. The “-01” position typically indicates a build that supports a speed/Keyphasor channel along with vibration channels. If you need us to verify the exact channel map and relay count against your P&ID, we can confirm before shipping.
Technical Specifications

Application Fields
The 1900/65A is commonly deployed on:
- Water & wastewater – pump skids, aeration blowers, and lift stations
- Chemicals & refining – auxiliary pumps, cooling tower fans, and small gearboxes
- Power generation – condensate and boiler feed pumps, ID/FD fans
- Food & beverage – process pumps and packaging line drives
- Mining & cement – conveyor drives, ventilation fans, slurry pumps
Advantages & Value
- Right-sized cost for essential assets – In many cases, it’s far more economical than a rack system while still providing protection-level alarms.
- Simplified integration – 4–20 mA and Modbus RTU make it straightforward to drop into existing control schemes.
- Sensor flexibility – Reuse existing Bently Nevada prox probes or industrial accelerometers to minimize retrofit costs.
- Serviceability – Buffered outputs and front-access wiring typically reduce troubleshooting time.
- Lead time and lifecycle – Seems to be easier to source than larger systems, and firmware/config tools are stable across the series.
Installation & Maintenance
- Cabinet & mounting – Install on 35 mm DIN rail or a rigid back panel inside an IP54 (or better) enclosure; allow ventilation clearance around the unit.
- Power & grounding – Use a clean 24 VDC supply; bond shields at the monitor end; maintain a solid protective earth to reduce noise.
- Wiring practices – Route transducer and Keyphasor cables away from VFD power; use twisted/shielded pairs; keep sensor cables and relay wiring segregated.
- Commissioning – Perform sensor checks (gap on proximities; bias on accelerometers), verify 4–20 mA scaling, and test alert/danger setpoints with simulated inputs.
- Routine maintenance – Quarterly visual inspection and connector re-torque; annual alarm logic review; keep firmware/config backups aligned with site standards.
Quality & Certifications
- Typically supplied with CE and UL/cUL compliance for industrial use
- RoHS-conformant build in most shipments
- Manufactured under ISO 9001 quality systems (vendor-level)
- Our warranty coverage: 365 days
