Bently Nevada 135613-01 High Temperature Case Expansion Transducer Assembly

Overview

The Bently Nevada 135613-01 is a High Temperature Case Expansion Transducer Assembly. Engineers use it in Turbine Supervisory Instrumentation (TSI) to monitor thermal expansion. It accurately measures the casing growth of large turbines during startup and operation. This monitoring helps prevent misalignment and mechanical damage caused by uneven expansion. Additionally, it supports predictive maintenance by detecting abnormal thermal behavior early.
