Product Overview

The Bently Nevada 24765-02-00 is a high-performance Case Expansion Transducer, a specialized Linear Variable Differential Transformer (LVDT) designed to measure the thermal growth of turbine casings and structural frames. In large turbomachinery, such as steam turbines and large compressors, the casing expands significantly as it heats up during startup and operation. The 24765-02-00 provides critical data on this expansion, ensuring that the machine is expanding uniformly and symmetrically. This monitoring is essential to prevent structural stress, binding of sliding feet, and potential catastrophic damage caused by uneven thermal growth.

Designed for integration with the Bently Nevada 3500/45 Displacement Monitor or similar systems, the 24765-02-00 converts linear mechanical motion into a precise DC voltage signal. This specific model features a 4-inch (101.6 mm) linear range, making it suitable for large machines with substantial thermal growth. The transducer is built to withstand the harsh environments of power generation facilities, including high temperatures and vibration. By utilizing the Bently Nevada 24765-02-00. operators can verify that the turbine casing is “breathing” correctly, protecting the alignment between rotating and stationary components.
