The Bently Nevada Model 330180-91-00 Proximitor Sensor is the advanced electronic signal conditioning module of the industry-standard 3300 XL Proximity Transducer System, engineered and manufactured by Bently Nevada (a Baker Hughes business). Fully compliant with the American Petroleum Institute API 670 standard, this precision transducer system serves as the worldwide benchmark for continuous non-contacting machinery protection and diagnostic monitoring on critical rotating turbomachinery.

The operating architecture of the 330180-91-00 generates a high-frequency radio frequency (RF) signal transmitted to the sensing coil of an eddy current proximity probe. As the gap distance between the probe tip and the conductive metallic shaft (standard calibration target: AISI 4140 steel) fluctuates due to dynamic vibration or static displacement, eddy currents induced in the shaft surface alter the RF oscillation amplitude. The Proximitor demodulates these amplitude variations, outputting a continuous DC voltage strictly linear to physical gap changes at a calibrated sensitivity of 7.87 V/mm (200 mV/mil). The output delivers simultaneous static position information (axial thrust) and dynamic frequency/amplitude data (radial shaft vibration).

Configuration Breakdown for Model 330180-91-00:
- 330180: 3300 XL Proximitor Sensor signal conditioning unit.
- 91 (Total Length and Mounting Option): 9.0 metre (29.5 feet) total electrical system length configured with integrated 35mm DIN-rail mounting clips (DIN-mount).
- 00 (Agency Approval Option): Standard industrial unapproved version (No hazardous area approval required).

A cornerstone benefit of the 3300 XL series is complete component interchangeability: probes, extension cables, and Proximitor sensors configured for 9.0m systems can be replaced or interchanged in the field without the requirement of matching individual components or performing bench recalibration. Built with superior RFI/EMI noise immunity and housed in a rugged, moisture-resistant non-conductive polymeric casing, the 330180-91-00 ensures stable, drift-free 24/7 continuous operation across an extensive temperature range of -51°C to +100°C.
