General

  • Manufacturer GE / Bently Nevada
  • Model 21000-28-05-00-041-03-02
  • Condition New Original ready stock
  • Product Family 21000-30-05-00-041-03-02,21000-318-05-00-041-03-02,21000-28-10-00-041-03-02

  • Key Rotating Machinery Monitoring: Widely used for monitoring radial vibration, axial displacement, and speed (keyphasor) in steam turbines, centrifugal compressors, large pumps, and generators.
  • External Adjustment Requirements: Allows maintenance personnel to adjust the gap between the probe and the shaft by rotating the probe externally without disassembling the machine casing, greatly reducing maintenance downtime risks.
  • Harsh Environment Protection: Provides a barrier for internal probes and cable connections, protecting them from oil, moisture, dust, and mechanical damage in industrial environments.
  • No Firmware: This product consists of a metal housing, seals, locking nuts, and conduit. It contains no internal electronic chips, microprocessors, or software; therefore, there is no concept of firmware updates.
  • Hardware Maintenance: "Updates" typically refer to replacing sealing O-rings, base adapters, or replacing older probes (such as the 7200 series) with the latest 3300 XL series probes.
  • This component is not programmable; its functionality is entirely achieved through mechanical configuration.
  • On-site Mechanical Adjustment: Although it cannot be programmed via software, manual mechanical adjustment is required during installation—that is, rotating the probe inside the housing until the downstream monitoring system (such as the 3500 system) displays the correct DC gap voltage.
