Product Details:

The BENTLY NEVADA 135613-02 case expansion transducer is a high-temperature LVDT sensor assembly, designed to measure the thermal expansion of steam turbine casings in rotating machinery protection systems. This LVDT sensor accurately captures the linear displacement caused by thermal expansion or contraction of the turbine housing during startup, shutdown and steady-state operation. The turbine expansion sensor converts physical displacement into standard electrical signals and transmits measurement data to Bently Nevada 3500 monitor racks, helping operators monitor casing growth and avoid thermal stress, casing distortion and rubbing between rotor and stator. It adopts robust stainless steel construction, can withstand high temperature and vibration in turbine field environments. The model 135613-02 provides a 50.8 mm (2 inch) linear measurement range with a 152.4 mm sensing rod. The assembly features stable linearity and excellent repeatability, supporting long-term continuous online measurement. It is widely used on large steam turbines in power generation and petrochemical plants, providing critical casing expansion data for machinery condition monitoring and thermal management.
