The Bently Nevada 330180-X1-05 145004-102 is a 3300 XL Proximitor Sensor used in industrial machinery protection and condition monitoring systems. It functions as a signal conditioning component within an eddy-current proximity transducer system, converting proximity probe measurements into electrical signals for shaft vibration and displacement monitoring.
This configuration belongs to the Bently Nevada 3300 XL 8 mm proximity transducer family. It operates together with a compatible proximity probe and extension cable to measure the distance between the probe tip and a conductive rotating shaft. Changes in this distance produce corresponding electrical output variations that can be processed by machinery monitoring equipment.
The 145004-102 modification is associated with a 9-meter transducer system and an X1 DIN-rail mounting arrangement. It is suitable for installations requiring this particular system length and mounting configuration.
Typical applications include steam turbines, gas turbines, centrifugal compressors, industrial pumps, and other rotating machinery where continuous shaft vibration and relative displacement monitoring is required.

The 330180-X1-05 operates through eddy-current proximity measurement. It forms part of a complete transducer assembly consisting of a Proximitor Sensor, extension cable, and proximity probe.
The proximity probe generates a high-frequency electromagnetic field at its sensing tip. When positioned near a conductive shaft surface, the electromagnetic field induces eddy currents in the target material.
Changes in the distance between the probe tip and the shaft affect the electromagnetic response. The Proximitor Sensor processes this response and converts it into a proportional output voltage.
The nominal scale factor is 7.87 V/mm (200 mV/mil). Within the applicable linear measurement range, changes in shaft position produce corresponding output voltage variations.
The monitoring system receives the output signal and uses it to evaluate shaft vibration, relative displacement, and other machinery operating conditions.
Typical Measurement Arrangement:
Rotating Shaft → 3300 XL 8 mm Proximity Probe → 9 m Extension Cable → 330180-X1-05 Proximitor Sensor → Machinery Monitoring System
The recommended probe gap is approximately 1.27 mm (50 mils) for the applicable system configuration. Correct probe calibration, target material, cable compatibility, and installation conditions are necessary to maintain measurement accuracy.
The 330180-X1-05 functions as the signal conditioning component between the proximity probe assembly and the machinery monitoring system.
In a typical turbine or compressor installation, proximity probes are positioned near the rotating shaft to detect radial vibration or axial displacement. The probe signals travel through the compatible extension cable to the Proximitor Sensor, which generates the corresponding electrical measurement output.
The monitoring equipment receives these signals and evaluates machinery operating conditions against configured alarm and protection limits.

The 145004-102 modification identifies a specific configuration of the 330180-X1-05 Proximitor Sensor. This configuration is associated with a 9-meter system length and DIN-rail mounting. The complete ordering number should be checked when selecting a replacement.
The specified configuration is associated with a 9-meter transducer system. A different cable arrangement should not be substituted without checking the complete probe, extension cable, and sensor combination against the required system calibration.
The X1 configuration identifies DIN-rail mounting. The sensor can be installed on a compatible 35 mm DIN rail within the machinery monitoring cabinet.
Incorrect probe gap, incompatible extension cables, damaged connectors, unsuitable target material, unstable supply voltage, or electrical interference can affect measurement accuracy. The complete transducer assembly should be checked during troubleshooting.
