330103-00-11-50-02-00 | Bently Nevada | 3300 XL 8 mm Probe

A. Technical Overview

The Bently Nevada 330103-00-11-50-02-00 is an 8 mm diameter proximity probe used in eddy-current-based shaft vibration and position monitoring systems. It mounts directly to machine casings and generates a high-frequency electromagnetic field; changes in target distance (e.g., shaft displacement) modulate the field, inducing a proportional voltage shift in the probe coil. This analog signal transmits to a 3300 XL extension cable and terminates at a 3300/3500 series monitor rack (e.g., 3500/22M, 3500/42), where it undergoes demodulation, filtering, and scaling. The probe itself contains no active electronics—signal conditioning occurs exclusively in the rack-mounted monitor. It interfaces with Bently Nevada 3500 System architectures and integrates into broader DCS environments including Experion PKS (via 3500 HART or Modbus TCP gateways) and SIMATIC S7-400 (via analog I/O modules and 3500 system integration). No bus protection is provided by the probe; isolation and surge suppression are handled at the monitor module level (e.g., 3500/22M input channel isolation: 1500 V_RMS).

C. Operational Capabilities

This probe monitors radial shaft vibration, axial position, and differential expansion in rotating machinery. In Oil & Gas, it operates on centrifugal compressors (e.g., GE PCL, Siemens SGT-400) where continuous uptime mandates G3 conformal coating for resistance to H₂S, salt mist, and hydrocarbon vapors. In Power Generation, it supports turbine-generator trains (e.g., Alstom KF, Mitsubishi M701F) with SIL 2 capability when paired with 3500/22M modules and redundant cabling per IEC 61508. In Aerospace ground-test facilities, it withstands thermal cycling during engine run-up tests (−25 °C to +120 °C ambient). Hot-swap support applies only to the monitor rack—not the probe—but mechanical design allows replacement under shutdown without disassembling adjacent sensors. Cable length options (5 m, 9 m, 15 m) maintain signal integrity up to 100 kHz bandwidth.

D. Technical FAQ

Q1: Does this probe require firmware or software version matching with 3500 rack firmware?

No. The 330103-00-11-50-02-00 is a passive transducer. It imposes no firmware dependencies on the 3500 system. All calibration, scaling, and alarm logic reside in the monitor module (e.g., 3500/22M, 3500/42). Firmware version affects only digital communication (Modbus, HART) and self-diagnostics—not analog signal acquisition from this probe.

Q2: How do I match this probe to a specific 3300 XL extension cable and monitor module?

Select the extension cable using the full part number’s suffix digits: “-50” = 5 m length; “-02” = standard temperature rating (−25 °C to +85 °C); “-00” = standard connector (10-32 UNF). Pair with 3300 XL-series cables (e.g., 330130-05-00-00 for 5 m). Use only with 3300/3500 monitor modules rated for 8 mm probes (e.g., 3500/22M, 3500/42). Do not use with legacy 3300 Non-XL monitors—the XL series uses different oscillator frequency and sensitivity curves.
