Description

The Bently Nevada 3300/48 Case Expansion Monitor is a specialized rack-mounted module engineered to track the thermal expansion of turbine casings relative to the machine foundation. This monitoring is essential for large rotating equipment, such as steam turbines, where monitoring casing growth is vital to prevent mechanical interference and ensure operational safety. The module provides continuous signal processing and compares real-time expansion data against user-defined alarm setpoints to facilitate predictive maintenance.

Features

  • Provides continuous measurement of casing expansion relative to the foundation.
  • Integrated alarm setpoint comparison for Alert and Danger conditions.
  • Supports input from proximity probes or LVDTs for flexible sensing configurations.
  • Features front-panel LED indicators for system status, including OK, Bypass, Alert, and Danger.
  • Standard relay outputs for external alarm integration.
