PRODUCT DESCRIPTION

Differential expansion proximity probe

Bently Nevada 330876-02-50-01-00 is a differential-expansion probe. It is the probe element in a matched differential-expansion measuring system. The complete sensing chain observes conductive-target movement relative to the machine casing; probe geometry, total electrical length and signal-conditioner calibration must be selected for the actual turbine installation.

The order selects the stated probe geometry, lead length and cable construction. Confirm the mounting arrangement and target clearance against the supplied assembly. The probe is only one system element and cannot establish measurement range or monitoring compatibility independently.
ACTUAL APPLICATIONS

Applications for 3300 XL 50 mm

These applications describe manufacturer-documented family use. They do not establish that this exact ordering code was installed at a named customer site.
  • 01 · TURBINE COLLARS

    Same-side differential-expansion measurements

    Two matched sensing channels can observe the same collar side when target size and expected rotor movement fit the documented range. Preserve the ordered mounting and connection options.
  • 02 · COMPLEMENTARY CHANNELS

    Opposite-side collar measurements

    The manufacturer describes complementary transducers observing opposite collar sides to extend the differential-expansion arrangement. Confirm the complete sensor-to-monitor configuration before commissioning.
  • 03 · ROTOR MOVEMENT

    Steam-turbine expansion monitoring

    The sensing chain observes rotor movement relative to the machine casing; select the target geometry and monitoring configuration for the expected thermal growth. Check the installation limits rather than selecting by appearance alone.

Information

DIFFERENTIAL EXPANSION PROXIMITY PROBE

Integrating 330876-02-50-01-00

It is the probe element in a matched differential-expansion measuring system. The complete sensing chain observes conductive-target movement relative to the machine casing; probe geometry, total electrical length and signal-conditioner calibration must be selected for the actual turbine installation.
A replacement or upgrade requires the matching probe, extension cable and Proximitor Sensor family. Published compatibility with a monitor does not permit mixing different sensing families or ignoring the total electrical length.
Protect connectors, preserve cable bend radius and install the target geometry specified for the measurement. Do not apply a short-term probe temperature allowance to the extension cable or remote sensor.

Features:

  • Match the complete ordering identity, mounting interface, electrical connections and operating limits
  • Follow the applicable installation instructions
  • Confirm unverified configuration details
The 330876-02-50-01-00 differential-expansion probe requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY

Verify the complete replacement identity before commissioning

Replacement of 330876-02-50-01-00 requires comparing the complete ordering identity, mounting interface, electrical connections and operating limits. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
A replacement or upgrade requires the matching probe, extension cable and Proximitor Sensor family. Published compatibility with a monitor does not permit mixing different sensing families or ignoring the total electrical length.
No verified exact-order discontinuation date, product revision or designated successor is asserted. Document revisions identify the reference literature, not hardware changes to the supplied product. Unconfirmed replacement options must be resolved before substitution.

Features:

  • Preserve the complete ordering identity
  • Compare the installed electrical and mechanical interfaces
  • Do not infer hardware revisions or successor models
The 330876-02-50-01-00 differential-expansion probe requires replacement verification against the complete installed configuration and current manufacturer documentation.
