Bently Nevada 1900/27 Single-Channel Vibration Monitor
Manufacturer: Bently Nevada
Product Number: 1900/27
Category: Single-Channel Vibration Monitor
Application: Continuous health monitoring of rotating machinery
Measurement Type: Single-channel vibration monitoring for manufacturing, energy, and water treatment
Product Description
The Bently Nevada 1900/27 is a compact, standalone vibration monitor designed for continuous health monitoring of rotating machinery in industries such as manufacturing, energy, and water treatment. As a single-channel solution, the 1900/27 supports compatible Bently Nevada 200150/190520 accelerometers and converts raw vibration signals into peak velocity units for real-time analysis. It features a built-in 4–20 mA output for integration with PLC/SCADA systems, along with configurable alarm relays for immediate fault notification. With dual power options (AC 85–264 V or DC 18–36 V) and Modbus RTU/RS485 connectivity, the 1900/27 balances flexibility and reliability in both critical and general-purpose applications.
Technical Specifications
| Parameter | Specification |
|---|---|
| Model | 1900/27 |
| Input Type | Single-channel vibration (accelerometer) |
| Sensor Compatibility | Bently Nevada 200150/190520 accelerometers |
| Input Sensitivity | 100 mV/g |
| Max. Acceleration | 20 g peak |
| Power Supply | AC: 85–264 VAC, 47–440 Hz / DC: 18–36 VDC |
| Outputs | 4–20 mA analog, 2 alarm relays (SPST) |
| Communication | Modbus RTU/RS485 |
| Dimensions | 17.8 cm × 12.7 cm × 8.9 cm |
| Weight | 0.68 kg |
Advantages and Features
- Cost-Effective Protection: Single-channel design reduces upfront costs while maintaining Bently Nevada’s reliability.
- Wide Power Range: AC/DC compatibility ensures suitability for diverse industrial environments.
- Modbus Integration: Seamless integration with digital control systems for centralized monitoring.
- TrendMaster 2000 Compatibility: Optional interface module (TIM) enables expansion into Bently’s advanced vibration analysis network.
- Local Display: Real-time vibration readings via optional remote display (up to 75 meters).
Application Areas and Use Cases
Industry Applications:
- Manufacturing: Motors, pumps, and conveyor systems.
- Energy: Small turbines and generators.
- Water/Wastewater: Centrifugal pumps and blowers.
Case Study: A food processing plant deployed the 1900/27 on packaging line motors. Early detection of imbalance via configurable alerts reduced unplanned downtime by 20%, saving $150K annually.
Competitor Comparison
- Superior Flexibility: Supports both AC/DC power and Modbus/analog outputs, unlike single-protocol alternatives.
- Compact Design: 30% smaller than legacy single-channel monitors, ideal for retrofitting.
- Scalability: Easy upgrade to Bently’s TrendMaster 2000 system for predictive maintenance.
Selection Recommendations
- Channel Requirements: Opt for the 1900/27 for single-point monitoring; choose the 1900/65A for multi-channel needs.
- Power Type: Select AC or DC versions based on existing infrastructure.
- Integration Needs: Pair with TIM module if future expansion into TrendMaster 2000 is planned.
Precautions
- Sensor Wiring: Use shielded cables to prevent EMI interference.
- Alarm Thresholds: Calibrate setpoints according to machinery manufacturer guidelines.
- Environmental Conditions: Ensure operating temperature (0–50°C) and humidity (5–95% non-condensing) compliance.
