Product Introduction: 3300/48-03-02-01-00
The 3300/48-03-02-01-00 is a 4-20 mA Dual-Channel Proximity Transducer System from the Bently Nevada 3300 series. This system is designed for monitoring radial vibration or axial position of a machine shaft using two independent eddy-current proximity probes. Each channel includes a proximitor (transducer) that converts the probe's gap signal into a standardized 4-20 mA output, which is proportional to the vibration displacement or position of the shaft. This dual-channel configuration is ideal for monitoring both X and Y axes of a bearing or for redundant monitoring schemes, providing robust machinery protection with easy integration into control systems.

Application Scenarios
This dual-channel system is a versatile solution for comprehensive machinery protection and condition monitoring.
Radial Vibration Monitoring on Bearings:
Installed in pairs (X and Y directions) on a single bearing to capture the full orbital motion of the shaft, essential for detecting imbalance, misalignment, and oil whirl in turbines and compressors.
Axial Position Monitoring:
Used with a single probe to monitor the thrust position of a rotor, protecting turbines and compressors from catastrophic damage due to excessive rotor float.
Redundant Monitoring Schemes:
Provides a backup channel for critical measurement points, ensuring continuous protection even if one channel fails, which is crucial for high-availability systems.
Integration into Control Systems:
The independent 4-20 mA outputs for each channel allow for straightforward connection to PLCs, DCS, or SCADA systems for plant-wide monitoring, alarm, and shutdown functions.
General Rotating Machinery:
Used on critical pumps, motors, and fans to provide reliable vibration data for predictive maintenance and to prevent unplanned downtime.
