Bently本特利135613高温机壳膨胀传感器应用

     Bently本特利135613高温机壳膨胀传感器应用于大型汽轮机机壳热膨胀测量 。机壳热膨胀是透平监测仪表(TSI)的一项重要的位移测量参数。机壳膨 胀（有时称为壳体热膨胀）是指机壳在机器启动或在运行期间产生 的热膨胀。机壳膨胀传感器系统通常安装在与汽轮机机壳固定端相 对的基础上，并提供壳体相对于基础膨胀的信息。

Bently本特利135613高温机壳膨胀传感器工作原理

       机壳膨胀传感器系统采用LVDT来测量机壳的热膨胀。 LVDT有一个连杆和机器相连。当机壳膨胀时，连杆在LVDT内移动， 引起LVDT信号变化。信号经过调理后到监测器上，用于显示和报 警。机壳膨胀应当使用双重传感器并排来测量。这种测量方式可以测量 机壳滑动支脚的位置，当一个支脚受到阻碍或被卡住时，将导致机 壳变形和机器损坏。双重机壳膨胀传感器系统与3300或3500监视器 使用，可以对机壳测量提供报警信息。高温双重机壳膨胀传感器系 统只能与3500/45位移监视器兼容。

Bently Bentley 135613 High temperature housing expansion sensor applications

Bently Bentley 135613 High temperature casing expansion sensor is applied to the thermal expansion measurement of large turbine casing. Thermal expansion of casing is an important displacement measurement parameter of turbine monitoring instrument (TSI). Housing expansion (sometimes called housing thermal expansion) refers to the thermal expansion of the housing during machine start-up or during operation. The housing expansion sensor system is usually installed on the basis of the fixed end of the turbine housing and provides information about the housing expansion relative to the foundation.

Bently Bentley 135613 High temperature housing expansion sensor working principle

The casing expansion sensor system uses LVDT to measure the thermal expansion of the casing. The LVDT has a connecting rod connected to the machine. When the housing expands, the connecting rod moves within the LVDT, causing the LVDT signal to change. The signal is conditioned to the monitor for display and alarm reporting. Housing expansion should be measured using dual sensors side by side. This measurement method can measure the position of the sliding foot of the housing, and when one foot is obstructed or stuck, it will cause deformation of the housing and damage to the machine. Dual housing expansion sensor systems are used with 3300 or 3500 monitors to provide alarm information for housing measurements. The high temperature dual housing expansion sensor system is compatible only with 3500/45 displacement monitors.
