Dual-Channel Measurement Capabilities

The 3300/16-13-01-02-00-00-00 monitors two independent vibration channels in an XY configuration. This arrangement enables radial vibration measurement at two orthogonal positions on the shaft. Each channel simultaneously measures both vibration amplitude and gap voltage. Operators can switch between vibration and gap modes for comprehensive shaft condition assessment. The frequency response from 0.5 Hz to 5 kHz captures low-speed and high-frequency vibration events.

Probe Excitation and Signal Conditioning

This monitor provides -24 V DC excitation for powering eddy‑current proximity probes directly. The 3300/16-13-01-02-00-00-00 also processes the probe’s gap voltage signal for position monitoring. Precision demodulation circuits extract vibration components from the carrier signal effectively. The module includes filtering to reject noise and enhance signal quality. Such comprehensive conditioning ensures accurate vibration and gap measurements simultaneously.

Alarm Configuration and Outputs

The 3300/16-13-01-02-00-00-00 offers Alert and Danger setpoints for each vibration channel independently. Users can adjust these thresholds using potentiometers on the module front panel. Each channel provides two SPDT relay outputs for external alarm annunciation. The module also outputs a 0–10 V gap signal for shaft position monitoring. Additionally, each channel supplies a 4–20 mA vibration output for integration with control systems.

Gap Voltage Monitoring

The 3300/16-13-01-02-00-00-00 includes gap voltage measurement for shaft position surveillance. This feature allows operators to observe static shaft position changes due to load variations. The gap output appears as a 0–10 V DC signal proportional to the probe’s distance. This measurement proves invaluable for identifying shaft movement and bearing wear. Consequently, operators can detect alignment issues and thrust position changes promptly.

Integration with 3300 Monitoring Systems

The integrates seamlessly with the 3300 chassis and system monitor. This module communicates system status through the backplane and front-panel indicators. The XY configuration complements other vibration monitors for comprehensive machine protection. System engineers can combine this module with temperature and speed monitors in the same rack. The module’s outputs interface with DCS and PLC systems for centralized data acquisition.

Mechanical Design and Installation

The comes as a plug-in module measuring 165 mm × 25 mm × 102 mm. This module weighs 0.30 kg and occupies one slot in the 3300 chassis. The front panel features LED indicators for power, channel OK, Alert, and Danger. A locking handle ensures secure seating within the backplane connector. The module’s lightweight design simplifies insertion and removal during maintenance.

Power and Electrical Characteristics

The draws 110 mA from the +24 V DC backplane supply. This module generates the required -24 V excitation for connected eddy-current probes. The internal excitation eliminates the need for separate external power supplies. The module’s current consumption remains low despite powering two probes. This efficiency reduces heat generation and enhances overall system reliability.

Application Suitability

The suits critical turbomachinery including steam turbines and centrifugal compressors. This monitor excels in applications requiring both vibration and shaft position data. The XY configuration provides complete radial vibration coverage for predictive maintenance programs. The module handles machinery in petrochemical plants and power generation facilities effectively.

Operational Guidance

Insert the 3300/16-13-01-02-00-00-00 into an available slot in the 3300 chassis. Connect the eddy‑current probes to the front-panel terminals for each channel. Set the vibration full-scale range and measurement units using internal switches. Adjust Alert and Danger setpoints with the front-panel potentiometers. Verify gap voltage readings to confirm correct probe installation. Monitor front-panel LEDs for normal channel status and alarm conditions.
