Features:
- The 330780-50-05 features SpringLoc terminal strips that eliminate screw-type clamping mechanisms for faster, tool-free wiring.
- This model includes improved RFI/EMI immunity that achieves European CE mark approvals without shielded conduit or metallic housings.
- The 330780-50-05 is designed with a thin form factor supporting both high-density DIN rail and traditional panel mount configurations.
The 330780-50-05 provides essential signal conditioning functions common to the 3300 XL system, and is a critical component directly affecting the accuracy of machinery monitoring applications. Its thin design allows it to be mounted in either a high-density DIN-rail installation or a more traditional panel mount configuration. The 330780-50-05 features SpringLoc terminal strips that require no special installation tools and facilitate faster, highly robust field wiring connections by eliminating screw-type clamping mechanisms that can loosen over time from vibration.
The 330780-50-05 offers improved RFI/EMI immunity that allows the sensor to achieve European CE mark approvals without any special mounting considerations. This RFI immunity also prevents the transducer system from being adversely affected by nearby high frequency radio signals, eliminating the need for special shielded conduit or metallic housings. The 330780-50-05 delivers consistent, reliable performance while reducing installation costs and complexity, making it ideal for modern control cabinets.
The 330780-50-05 solves the critical pain point of upgrading legacy 7200-series systems to modern 3300 XL technology with complete component replacement. Its advanced RFI/EMI immunity eliminates the need for shielded conduit, while SpringLoc terminals simplify field wiring. The 330780-50-05 ensures reliable vibration and position monitoring for critical machinery applications such as radial vibration, axial thrust, and Keyphasor measurements on steam turbines, compressors, and generators.
The 330780-50-05 Bently Nevada 3300 XL 11 mm Proximitor Sensor may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Power Industry: Thrust position and differential expansion monitoring of rotors in large steam turbine generator sets.
- Petrochemical and Natural Gas Industries: Shaft trajectory and vibration analysis of high-power centrifugal compressors and large reciprocating compressors.
- Hydropower: Monitoring large-scale displacements caused by hydraulic impact during the operation of hydroelectric turbine units.
- Humidity Protection: Internal circuitry is fully potted, compliant with IEC 68-2-3 humidity and heat testing, and can withstand 100% condensation.
- Electromagnetic Compatibility (EMC): Excellent radio frequency interference (RFI) immunity, maintaining stable signal even in strong electromagnetic fields (such as near large generator sets).
- Hazardous Area (-05 Certification): Permitted for installation in explosive hazardous environments in Zone 0/1/2 or Division 1/2 (must be used with safety fencing or explosion-proof enclosure).
- Signal Conversion: Converts the gap changes detected by the probe into an analog voltage signal proportional to the distance (standard sensitivity is 3.94 V/mm or 100 mV/mil).
- Real-time Monitoring: The signal is typically output to the Bently Nevada 3500 monitoring system. If displacement or vibration exceeds preset values, the monitor will trigger an alarm or interlock shutdown logic.
- Self-Diagnostic Protection (Not OK): The preamplifier automatically detects whether the probe circuit is open-circuited or short-circuited. If a fault is detected, its output voltage will enter the "Not OK" zone, and the monitor will immediately disable the alarm for that channel to prevent false tripping.
