Product Overview

The 24765-01-01 is a high-precision Case Expansion Transducer Assembly (DC) designed for the Bently Nevada monitoring suite. Unlike standard vibration probes, this transducer is specifically engineered to measure the absolute thermal growth of machine casings relative to the foundation. This is critical for large steam turbines and industrial machinery where thermal expansion must be monitored to ensure the unit remains within structural design tolerances during startup, steady-state operation, and shutdown cycles. This assembly features a spring-return mechanism to ensure continuous contact with the machine casing, providing a reliable DC voltage output proportional to the expansion distance.
