Two-Channel Radial Vibration and Position Monitoring Module
The Bently Nevada 3300/16-15-01-03-00-00-02 provides dual independent channels for continuous radial vibration and shaft position measurement. This monitor accepts input signals from two 3300 XL 8 mm proximity probe systems simultaneously. It directly replaces the earlier 3300/15 model while adding radial position gap alarm functionality. The module processes dynamic motion data to detect early mechanical distress in critical rotating machinery.

Measurement and Signal Processing Capabilities
The monitor continuously tracks both dynamic vibration amplitude and static gap voltage from eddy-current probes. Its calibrated input stage maintains a precise 200 mV/mil sensitivity for accurate displacement readings. A specialized internal filter design effectively suppresses crosstalk interference when you install multiple probes in close proximity within the same bearing housing. The front-panel LCD provides clear local status indication without any multiplexing artifacts.
Fault Detection and Output Flexibility
An integrated Not OK detection circuit actively monitors each probe channel for wire breaks or impedance faults. The system de-energizes the affected channel within 100 milliseconds upon detecting a transducer fault, thereby preventing false alarm trips. You can field-configure the recorder output options to 4-20 mA, 0 to -10 VDC, or +1 to +5 VDC signals. This output versatility enables straightforward integration with most DCS, PLC, and SCADA platforms.
Installation and Application Guidance
This module fits standard 3300 series rack mounting systems and operates reliably in harsh industrial environments. The monitor suits steam turbines, gas turbines, centrifugal compressors, and large pumps requiring continuous vibration surveillance. Its compact 192 x 140 x 89 mm enclosure and 1.02 kg weight simplify both retrofit and new installation projects.
