Description
Bently 1900 65A
Technical Specifications
- Model: 1900/65A
- Channels: 4 independent vibration inputs and 4 temperature inputs
- Relay Outputs: 6 programmable relays
- Analog Outputs: 4 buffered 4-20 mA outputs
Functional Features
- Multi-Sensor Compatibility: Each vibration channel can be software-configured to accept 2-wire or 3-wire accelerometers, velocity sensors, or eddy current displacement probes.
- Temperature Monitoring: Supports E, J, K, and T-type thermocouples for comprehensive machine health monitoring.
- Flexible Configuration: Parameters are defined via PC software and downloaded to the monitor via the built-in Ethernet interface.
Application Scenarios
Extensively used in power plants, chemical facilities, and steel mills to protect auxiliary equipment such as fans, compressors, water pumps, and motors.
Performance Parameters
- Display: Real-time vibration value display (Peak-Peak for displacement, Peak-Peak or RMS for velocity)
- Configuration Storage: Non-volatile memory retains settings during power loss
- Operating Temperature: Standard industrial range
Material Composition
Housed in a robust, industrial-grade enclosure designed for panel mounting, providing excellent EMI shielding and mechanical protection.
Structural Characteristics
Compact standalone module with front-panel LED status indicators, Ethernet port, and rear terminal blocks for sensor and relay wiring.
Working Principle
Receives analog signals from vibration and temperature sensors, conditions the signals, converts them to digital values, and compares them against user-defined alarm thresholds to trigger relays or analog outputs.
Installation Requirements
Mount in a standard control panel. Connect sensors using shielded cables and ensure proper grounding to prevent electrical noise interference.
Precautions for Use
Configuration files must be created and downloaded using Bently Nevada configuration software. Verify sensor type and sensitivity settings match the installed field devices.
