The absolute expansion sensor DT-2 is a device used to measure the thermal expansion of steam turbines. It consists of the sensor body, measuring rod, sensing element, signal conversion circuit, and output interface. The sensor body is usually made of high-temperature and high-pressure resistant materials to adapt to the harsh environment inside the turbine. The measuring rod is a part of the sensor, which is connected to the cylinder and extends as the cylinder expands. The signal conversion circuit is responsible for amplifying, filtering, and digitizing the signals generated by the sensing components, and the output interface transmits the processed signals to the control system or monitoring equipment, such as PLC or computer.

 

The main function of the absolute expansion sensor DT-2 is to measure the absolute expansion of the steam turbine. When the expansion exceeds the preset safety range, the sensor can trigger an alarm to remind maintenance personnel to take necessary measures. In addition, the data provided by the absolute expansion sensor DT-2 can help optimize the operating conditions of the steam turbine and reduce maintenance costs. In situations where excessive expansion may cause damage, sensor DT-2 can serve as a safety protection mechanism, automatically adjusting the operation of the turbine or triggering an emergency stop.
