The Bently Nevada 330180-12-CN is a high-performance 3300 XL Proximitor Sensor designed for critical machinery protection applications. As a core component of the 3300 XL 8mm Proximity Transducer System, this unit processes raw eddy current signals from proximity probes, converting them into proportional voltage outputs for vibration and position monitoring.

Features

  • Designed for fluid-film bearing machines, including centrifugal compressors, steam turbines, and large electric motors.
  • Supports complete interchangeability of probes, extension cables, and sensors, eliminating the need for individual bench calibration.
  • Backward compatible with existing 3300-series 5mm and 8mm transducer system components.
  • Extended operating temperature range for demanding industrial environments.
  • Agency-certified for hazardous locations, including CSA, ATEX, and IECEx compliance.

Technical Specifications

Model 330180-12-CN
System Length 1.0 meter (3.3 feet)
Output Resistance 50 Ohm
Operating Temperature -52 degC to +100 degC
Probe Tip Material Polyphenylene sulfide
Agency Approvals CSA, ATEX, IECEx
Power Requirements -17.5 Vdc to -26 Vdc

Applications

  • Gas & Steam Turbines: Monitoring radial vibration and axial thrust position to prevent rotor-to-stator contact.
  • Centrifugal Compressors: Tracking shaft stability and bearing health in oil and gas processing.
  • Large Pumps & Motors: Providing non-contact displacement data for sleeve bearing machines.
  • Generators: Real-time monitoring for condition-based maintenance programs.

Installation Guidelines

  • Ensure the system is powered down before connecting or disconnecting the probe and cable to the PROBE jack.
  • Connect the probe and extension cable to the Proximitor sensor; verify the output voltage between OUT and COM terminals.
  • Adjust the probe gap until the output reads -9.0 Vdc, representing the center of the 80-mil linear range.
  • Use a micrometer to verify calibration; the output should change by 2.0 Vdc per 10 mils of movement (200 mV/mil).
  • Maintain proper shielding and grounding practices to prevent EMI interference in high-voltage industrial areas.

FAQ

Is this sensor compatible with older 3300 systems?

Yes, the 3300 XL Proximitor Sensor is designed for backward compatibility with 3300 5mm and 8mm probes, allowing for system upgrades without replacing all existing field components.

What is the primary function of this unit?

It acts as the signal processing hub, converting eddy current signals from a proximity probe into a usable voltage output for machinery protection and condition monitoring systems.

What is the required power supply?

The unit typically operates on a supply voltage of -17.5 Vdc to -26 Vdc. Note that operating at voltages more positive than -23.5 Vdc may reduce the effective linear range.
