TD-2 expansion sensor with a measuring range of 0-80mm is one of the special products supplied by Sichuan Dongshen Automation Co., Ltd. It is mainly used for thermal expansion measurement of 1000MW steam turbine generator set. This product is made by using the new process of double dials and double LVDT, and is a product with excellent performance.



1、 Thermal expansion



The steam turbine cylinder expands due to heating during startup. If the expansion is uneven, the cylinder will tilt or tilt. This deformation will cause huge stress between the cylinder and the foundation, which will lead to misalignment. This phenomenon is usually caused by the "jamming" of the sliding pin system.



2、 TSI system



The MMS6000 system is an intelligent system. In addition to the conventional power module UES815 In addition to the 19 "chassis IMR011 and the communication module MMS6831, there are monitors such as MMS6312, MMS6220, MMS6120, MMS6110, and MMS6410. These monitors are dual channels, and each channel can be used independently. Each channel has independent reminders and corresponding 4~20mA and 0~10V outputs. The output is connected to the bus, and 485 or 232 communication can be conducted through the bus interface.

working principle



It consists of an LVDT (medium frequency differential transformer displacement sensor) and a protective cover. The LVDT is connected to the housing by a feeler rod. When the casing expands, the feeler rod moves in the LVDT, causing the LVDT signal to change. After adjustment, the signal is output to the monitor or DCS, PLC system for display and alarm.
