Product Overview

The Bently Nevada 330104-00-03-10-01-05 represents the industry gold standard in non-contact displacement sensing, specifically engineered for the 3300 XL 8mm Transducer System. This probe is a critical component for Turbine Supervisory Instrumentation (TSI), providing high-fidelity vibration and position data for steam turbines, centrifugal compressors, and power generation assets. It effectively captures micro-level shaft movements, converting eddy current variations into precise electrical signals for the Bently Nevada 3500 monitoring system. Designed for extreme reliability, this probe maintains its linear scale factor even in high-temperature bearing housings, ensuring that operations teams receive accurate data for both routine diagnostics and emergency machine protection logic.

Dimensional & Electrical Configuration

Model Suffix Engineering Logic

The 330104 series utilizes a metric thread profile (M10 x 1), and the specific suffix 00-03-10-01-05 defines the following technical parameters:

Unthreaded Length (-00)

The 00 suffix indicates a 0mm unthreaded length. This configuration provides a fully threaded probe body, offering maximum installation flexibility when mounting through brackets or custom machine casings.

Overall Case Length (-03)

The 03 designation specifies a 30mm overall case length. This compact mechanical footprint allows for deployment in shallow-depth bearing housings where interior space is at a premium.

Total Length (-10)

The 10 code confirms a 1.0 meter (3.3 feet) total cable length. This integral lead connects to the extension cable to form the complete electrical system, typically calibrated for a 5-meter or 9-meter total length.

Connector Option (-01)

Equipped with a miniature coaxial connector without a connector protector. This enables direct, low-profile coupling to the extension cable in protected conduit environments.

Agency Approval (-05)

The 05 suffix represents Multiple Approvals, encompassing ATEX, IECEx, and CSA certifications. This guarantees compliance for use in Class I, Division 1, and Zone 0 hazardous industrial locations globally.

Critical Technical Matrix

Precision Commissioning Protocol

During field installation, technicians must utilize a digital multimeter to verify the DC gap voltage. A quiescent gap voltage of approximately -10 VDC signifies that the probe is centered within its 80-mil linear range relative to the AISI 4140 steel target. Ensure a minimum clearance of 15mm from any adjacent metal to prevent side-loading interference, which can distort the eddy current field. To protect signal integrity, do not exceed a minimum cable bend radius of 25.4mm. All electrical connections should be housed in a grounded terminal box to shield the system from electromagnetic interference (EMI) prevalent in high-voltage industrial environments.

Machine Integration Advantages

The 3300 XL series is distinguished by its superior interchangeability, allowing this 330104 probe to work seamlessly with any 3300 XL Proximitor sensor of the same system length. Its PPS tip is highly resistant to synthetic lubricants and corrosive process gases, making it the preferred choice for petrochemical and oil & gas facilities. When integrated into a DCS like Honeywell Experion PKS or Siemens PCS7 via the 3500 rack, it facilitates advanced orbit and waterfall plot analysis. This allows for the early detection of oil whirl, misalignment, and unbalance, moving the plant from reactive maintenance to an optimized condition-based maintenance (CBM) strategy.

Field Support FAQ

Q1: Can I use this M10 probe in a 3/8-24 UNF threaded hole?

A1: No. The 330104 is a metric M10 x 1 probe. For imperial 3/8-24 threads, you must specify the 330101 or 330103 series to ensure correct mechanical fit and pressure sealing.

Q2: What happens if I use this 1.0m probe with the wrong extension cable?

A2: The total electrical length (Probe + Extension Cable) must match the Proximitor’s calibration (typically 5m or 9m). An incorrect total length will result in significant scale factor errors and non-linear output.

Q3: Is the 330104 probe compatible with older 3300 systems?

A3: While the 3300 XL series is backward compatible with many older 3300 systems, the scale factor and linearity are only guaranteed when used as a complete 3300 XL system. Consult your system manual for specific impedance matching.
