Product introduction

The Bently Nevada 1900/65A-00-00-02-00-01 is a compact, single-channel vibration monitor designed for standalone protection of rotating machinery in industrial environments. As part of Bently’s 1900 series—a legacy line focused on simplicity and reliability—it targets small-scale applications such as pumps, fans, and motors where complex system integration is unnecessary. Unlike the 3500/22M 288055-01, which excels in multi-point temperature monitoring for safety-critical systems, this module specializes in basic vibration protection, offering local alarm management without the need for a central controller.

Equipped with front-panel controls and a clear LCD display, the 1900/65A-00-00-02-00-01 allows on-site technicians to set vibration thresholds quickly, making it ideal for facilities with limited automation infrastructure. Its 115/230V AC power input eliminates dependency on specialized DC supplies, simplifying installation in remote locations. While it lacks the 3500/22M 288055-01’s Ethernet connectivity and ultra-precision, it delivers cost-effective protection by triggering relay outputs (e.g., shutdown or warning) when vibration exceeds user-defined limits—critical for preventing unplanned downtime in auxiliary equipment.

Core advantages and technical highlights

Simplified operation: The 1900/65A-00-00-02-00-01 features intuitive front-panel controls—rotary potentiometers for setting alarm thresholds and a backlit LCD showing real-time vibration levels. This eliminates the need for software configuration, making it accessible to maintenance teams without specialized training—a stark contrast to the 3500/22M 288055-01’s complex setup via 170180-01-00 software.

Standalone functionality: Designed to operate independently, the module requires no external controller to trigger protective actions. Its two Form C relays (configurable as “Warning” and “Danger”) can directly activate alarms or shutdown mechanisms, making it suitable for retrofitting into older machinery where integrating with a 3500-series system would be cost-prohibitive.

Cost-effective protection: Priced significantly lower than multi-channel 3500-series modules, the 1900/65A-00-00-02-00-01 offers essential vibration monitoring for budget-constrained applications. Its AC power compatibility and panel-mount design reduce installation costs, while its rugged construction ensures reliable performance in environments where the 3500/22M 288055-01’s conformal coating and surge protection would be overkill.

Versatile sensor support: Compatible with both proximity probes (for shaft vibration) and velocity transducers (for bearing vibration), the module adapts to different machinery types. This flexibility, combined with a 4-20 mA analog output, allows basic integration with local SCADA systems—though it lacks the 3500/22M 288055-01’s advanced protocol support (MODBUS TCP/IP, OPC UA).

Typical application scenarios

In a municipal water treatment plant, the 1900/65A-00-00-02-00-01 monitors a standalone booster pump using a 3300 proximity probe. Technicians set a “Warning” threshold at 500 μm and “Danger” at 1000 μm via front-panel controls. When vibration spikes due to impeller wear, the module triggers a local alarm (Warning) and, if levels exceed 1000 μm, shuts down the pump via its relay output—preventing catastrophic failure. Unlike the 3500/22M 288055-01, no external controller is needed, simplifying operation for the plant’s small maintenance team.

At a food processing facility, the module is installed on a conveyor motor, paired with a velocity transducer. Its 115V AC power input connects directly to the plant’s standard electrical system, avoiding the need for a 24V DC supply. The 4-20 mA output feeds vibration data to a local PLC, while the relays activate a visual alarm and conveyor stop mechanism. This setup provides essential protection at a fraction of the cost of a 3500-series system, where the 3500/22M 288055-01’s thermal monitoring would be unnecessary.

In a remote oil field, the 1900/65A-00-00-02-00-01 protects a small crude oil transfer pump. Its rugged design withstands the field’s temperature fluctuations (0°C to +50°C), while its standalone operation eliminates dependency on fragile communication links. When vibration exceeds thresholds, the module triggers a shutdown relay, preventing pump seizure during periods when on-site personnel are scarce— a scenario where the 3500/22M 288055-01’s complex features would be underutilized.

Installation, commissioning and maintenance instructions

Installation preparation: Mount the 1900/65A-00-00-02-00-01 on a control panel using the provided mounting brackets, ensuring a clear view of the LCD for operators. Connect the sensor (proximity probe or velocity transducer) to the terminal block using shielded cable, grounding the shield at the module end. Wire the 115/230V AC power supply, taking care to match the selected voltage setting (via internal jumper). Connect relay outputs to alarm/shutdown devices, ensuring wiring complies with local electrical codes.

Commissioning steps: Power on the module and verify the LCD displays “0” with no sensor connected. Attach the calibration tool (177232-01) to simulate vibration signals, adjusting the “Warning” and “Danger” potentiometers to desired thresholds (e.g., 500 μm and 1000 μm). Confirm that relays activate at the correct levels and that the 4-20 mA output scales linearly with input (e.g., 4 mA = 0 μm, 20 mA = 2000 μm). Test shutdown logic by triggering the “Danger” relay and verifying the connected equipment stops as intended.

Maintenance suggestions: Inspect monthly, checking terminal block connections for tightness and corrosion—clean with a dry cloth if needed. Calibrate semi-annually using the 177232-01 tool to ensure threshold accuracy, adjusting potentiometers if drift exceeds ±5%. Replace the LCD backlight annually (if dim) to maintain visibility. Unlike the 3500/22M 288055-01, no firmware updates are required, simplifying long-term maintenance.
