Description
Product Introduction & Engineering Value
Many balance-of-plant machines are too important to leave unmonitored but don’t justify installing a full rack-based protection system. The Bently Nevada 1900/65A-01-01-01-00-00 fills that gap by combining vibration, temperature, alarm, and machine health monitoring into a compact standalone package.
This configuration includes an attached operator display and DIN rail mounting, making it well suited for local control panels serving pumps, fans, motors, and auxiliary compressors. Maintenance personnel can review machine status directly at the equipment without adding a separate HMI.

Field Application & The “Trench” Experience
A municipal water treatment plant experienced repeated nuisance shutdowns on a vertical service water pump. Operators only knew that an alarm occurred—they had no local indication of whether the issue involved vibration, bearing temperature, or shaft position.
The maintenance department replaced an aging monitor with the 1900/65A-01-01-01-00-00. After configuring proximity probes and bearing RTDs, technicians used the attached display to observe machine conditions during startup. Within two operating cycles, they identified excessive vibration caused by pipe strain after recent maintenance. Correcting the piping alignment eliminated the alarms without replacing the pump.
Typical application scenarios include:
- Cooling water pump protection
- Induced draft and forced draft fan monitoring
- Auxiliary gearbox condition monitoring
Transparency SOP: QA & Testing
Every New Surplus or refurbished 1900/65A-01-01-01-00-00 is verified through a documented inspection process.
- Confirm the complete model code and option suffix.
- Inspect the LCD, keypad, housing, and DIN rail mounting hardware.
- Verify all transducer and temperature input channels using calibrated simulators.
- Test programmable relay operation and 4–20 mA analog outputs.
- Validate alarm indication, front-panel display, and internal diagnostics.
- Package the unit in anti-static protection with industrial-grade shock-resistant materials.

The Veteran’s Tech Trap Guide
⚠️ Don’t overlook the option codes.
The suffix 01-01-01-00-00 specifies 110–220 VAC power, an attached display, DIN rail mounting, no hazardous-area approvals, and no optional communications package. A different suffix may require different mounting hardware or power wiring.
⚠️ No optional communications doesn’t mean no configuration.
This version omits the optional communications package in the ordering code, but configuration is still performed through the monitor’s built-in setup interface using the supported configuration software. Always verify the required connectivity before commissioning.
PRO TIP:
Before replacing the monitor, save the existing configuration file. Restoring alarm limits, relay logic, and channel assignments from backup is considerably faster than manually recreating every parameter.
Dynamic FAQ
Q1. What does the model code 1900/65A-01-01-01-00-00 indicate?
It identifies a 1900/65A General Purpose Equipment Monitor configured with 110–220 VAC external power, an attached display, DIN rail mounting, no hazardous-area approvals, and no optional communications package.
Q2. Which sensors can this monitor accept?
It supports four configurable transducer inputs for proximity probes, velocity sensors, or accelerometers, plus four temperature inputs for RTDs and thermocouples.
Q3. Is this monitor suitable for large turbine-generator protection?
Generally, no. The 1900/65A is intended for essential and general-purpose rotating equipment. Large critical assets typically use systems such as the Bently Nevada 3500 Series for more advanced machinery protection.
Q4. Can this unit generate shutdown alarms?
Yes. It includes six programmable relay outputs that can be configured for OK, Alert, Danger, or custom alarm logic based on monitored conditions.
Q5. What does “New Surplus” mean?
A New Surplus unit is unused inventory sourced from OEM overstock, canceled projects, or excess plant inventory. It has not been placed into industrial service and is inspected before shipment.
Q6. Is warranty available?
Yes. Most industrial automation suppliers offer warranty coverage for both New Surplus and professionally refurbished units after documented inspection and functional testing. Warranty duration varies by supplier.
