Description：

The Bently Nevada 330180-X1-05 MOD:145004-15 is a 3300 XL Proximitor Sensor used as part of the 3300 XL 8 mm proximity transducer system. Operating together with a compatible proximity probe and extension cable, it processes probe signals and provides an output that reflects the distance between the probe tip and a conductive target surface. This information is widely used for shaft vibration, position, and displacement monitoring in rotating machinery.

Recognized for its stable measurement capability and consistent performance, the 3300 XL 8 mm system meets the requirements of API 670 for mechanical configuration, measurement accuracy, linear operating range, and temperature stability. The standardized architecture allows probes, extension cables, and Proximitor Sensors within the 3300 XL series to be used interchangeably, simplifying maintenance activities and reducing the need for individual component calibration during replacement.

Frequently asked questions

Q1: What does "MOD: 145004-15" mean?

Standard units are calibrated for 4140 steel. This MOD code means the sensor is specifically modified and tuned for ASTM A182 F6NM stainless steel shafts.

Q2: Can I use a standard 330180 sensor to replace it?

No. A standard sensor will read wrong magnetic properties on F6NM steel. This alters the 200 mV/mil scale factor and causes highly inaccurate readings or false alarms.

Q3: Does it need special probes or cables?

No. It connects to standard 3300 XL 8mm probes and extension cables. The custom tuning is fully inside the Proximitor box. Just ensure the total loop length (5m or 9m) matches.

Q5: Are there any specific limitations?

Factory calibration for this material is done at +23 °C (+73 °F). Performance metrics at extreme high or low temperatures may vary slightly from standard specs.
