Bently Nevada 1900/65A-00-00-01-00-00 Universal Equipment Monitor

The Bently Nevada 1900/65A-00-00-01-00-00 general-purpose equipment monitor bridges the gap between high-end rack protection and basic plant transmitters.It provides high-reliability, low-cost monitoring for vital auxiliary equipment—such as industrial pumps, cooling tower fans, air compressors, and small electric motors—that cannot justify a full-scale 3500 series installation.

The monitor houses highly stable 24-bit analog-to-digital converters (ADC) to manage high-precision sensor evaluation.Equipped with non-volatile memory architectures, the device maintains its internal configuration registers through complete plant power blackouts.Technicians can manipulate variables using specialized configuration software or check the exact real-time health levels using the integrated front display. 

• Model Designation String: 1900/65A General Purpose Equipment Monitor.

• Option Key Breakdown:

• Power Option (00): 18 to 36 Vdc operating range.

• Display Option (01): Attached local display (no extension cable).

• Mounting Option (00): None.

• Approvals Option (00): None.

• Communications Option (00): None.

• Dynamic Signal Inputs: 4 independent channels supporting 2/3-wire accelerometers, velocity pickups, or proximity probes.

• Temperature Signal Inputs: 4 independent channels matching E, J, K, and T thermocouples or 2/3-wire RTDs.

• Hardware Interlock Outputs: 6 programmable relay outputs (Alert and Danger status logic combinations).

• Analog Record Outlets: 4 individually configurable 4-20 mA recorder loops.

• Diagnostic Waveform Ports: Dedicated buffered electrical outputs for raw sensor signals.

• Internal ADC Resolution: 24-bit continuous sampling architecture.

• Physical Module Proportions: 196.9 mm x 149.4 mm x 97.8 mm (inclusive of the attached display module face).

• Module Core Mass: 0.77 kg (Net device weight without packaging elements).

• Thermal Limitations: Operating envelope from -20°C to +70°C (-4°F to +158°F).

• Stand-Alone Safety Execution: Acts completely independently to execute critical automated machinery shutdowns without relying on external network resources.

• Versatile Channel Profiling: Allows channels to be individually programmed to display radial vibration, axial displacement, position, or shaft speed.

• Comprehensive Alarm Delay Blocks: Configurable time delay parameters (adjustable from 0.1 to 60 seconds) eliminate nuisance trips caused by transient structural vibrations.

• Local Hardware Inspection: The attached display screen provides instant access to overall values, channel status lists, and the onboard 200-entry event log.

The 1900/65A-00-00-01-00-00 protection module scales essential condition tracking to balance-of-plant equipment:

• Water and Wastewater Utilities: High-volume effluent discharge pumps, intake blowers, and treatment mixers.

• Power Plant Auxiliaries: Induced draft (ID) and forced draft (FD) fans, cooling tower cells, and boiler feed pumps.

• Pulp, Paper, and Chemical Refining: Large electric motors, centrifugal extractors, process gearboxes, and auxiliary plant compressors.

Q1: What does the "01" display option mean for the 1900/65A-00-00-01-00-00 hardware?

A1: The "01" option specifies that the module is delivered with the local display/keypad assembly mounted directly to the front face of the monitoring unit, rather than as a separate component meant for remote panel mounting.

Q2: Can I track raw vibration waveforms using this monitor?

A2: Yes. The 1900/65A features dedicated, buffered output terminals that provide clean, unfiltered electrical access to raw sensor wave signals for external diagnostic tools or FFT analyzers.

Q3: Is an external power converter required to run this specific model?

A3: This specific configuration utilizes option code "00" for power, meaning it connects directly to a standard 18 to 36 Vdc industrial power source.If you need to use a 110/220 Vac line, an external step-down power converter is required.
