Channel Configuration and Measurement

The offers two independent channels for simultaneous machine point monitoring. Users can configure each channel for displacement, velocity, or acceleration measurement modes. This flexibility accommodates various sensor types and application requirements effectively. The module accepts input signals from eddy-current probes or velocity sensors. Each channel processes the input signal and generates a proportional 4–20 mA output.

Sensor Excitation and Signal Conditioning

This monitor provides -24 V DC excitation for powering eddy-current proximity probes. The conditions the probe signal through precision demodulation circuits. The module’s frequency response ranges from 0.5 Hz to 5 kHz for comprehensive vibration detection. Such wide bandwidth captures both low-speed machinery and high-frequency vibration components. The signal conditioning circuitry also incorporates filtering for noise rejection.

Alarm Setpoints and Relay Outputs

The includes two independent alarm setpoints per channel: Alert and Danger. Users can adjust these thresholds through front-panel potentiometers for specific machinery requirements. Each channel provides two SPDT relay outputs for external alarm annunciation. These relays activate when vibration levels exceed the configured setpoints. The module also includes a bypass feature for safe maintenance operations.

Output Signal and Integration

This vibration monitor generates a 4–20 mA analog output proportional to the measured vibration level. The delivers these outputs for integration with DCS and PLC systems. The 4–20 mA signal corresponds to the full-scale vibration range configured for each channel. Operators can use these outputs for continuous monitoring and trending in control systems. The module’s output scaling simplifies system integration without additional signal conditioning.

Mechanical Design and Installation

The arrives as a plug-in module measuring 165 mm × 25 mm × 102 mm. This module weighs only 0.28 kg and fits standard 3300 chassis slots. A front-panel locking mechanism secures the module firmly within the rack. The module’s compact design saves valuable space in monitoring cabinets. Front-panel LEDs provide clear status indication for power, channels, and alarms.

Power and Electrical Characteristics

The 3300/16-11-01-02-00-02-00 draws 100 mA from the chassis backplane power supply. This module obtains operating power through the backplane connector without external wiring. The monitor also generates -24 V DC for powering eddy-current probes. This internal excitation simplifies installation by eliminating separate probe power supplies. The module’s low power consumption reduces heat generation in the chassis.

Application and System Suitability

The protects a wide range of rotating machinery in various industries. This monitor suits turbines, compressors, fans, pumps, and motor applications effectively. Its dual-channel design allows monitoring of two bearing locations or machine points. The module integrates with Bently Nevada 3300 system racks and monitoring software. Furthermore, the 3300/16-11-01-02-00-02-00 supports machinery protection in power generation and oil refining facilities.

Operational Guidance

Insert the into an available slot in the 3300 chassis. Connect the sensor cables to the appropriate front-panel terminals for each channel. Set the measurement mode and full-scale range using the internal configuration switches. Adjust the Alert and Danger setpoints with the front-panel potentiometers. Verify the 4–20 mA output signal correlates with applied vibration levels. Monitor the front-panel LEDs to confirm normal channel status and alarm conditions.
