During the operation of power plant steam turbines, precise control of the opening of regulating valves is crucial for ensuring the safe, efficient, and economical operation of the turbine. The Digital Electronic Adjustment (DEH) system is a key technology to achieve this goal, and linear displacement sensors are an indispensable part of the DEH system. Through high-precision position feedback, it ensures that the steam turbine always operates in the optimal state.

The working principle of the LVDT Position Sensor TDZ-1-150 is to achieve precise measurement of valve position by converting physical displacement into electrical signals. It detects displacement through the principle of a transformer. When the central core rod moves, it will affect the phase difference between the two secondary coils, thereby changing the output voltage of the secondary coils. Due to the principle of LVDT, even if the distance of the core rod movement is very small, voltage changes can be detected, thus providing very high position resolution.

It can be seen that the high-precision positioning of the TDZ-1-150 displacement sensor relies on key components in its structure, including sensitive components, guide rails or supports, displacement mechanisms, and electronic circuits. The interaction of these components enables this sensor to provide very precise valve position feedback.

In addition, the design of the TDZ-1-150 sensor also considers environmental adaptability, including protective and sealing measures to prevent the impact of dust, moisture, and other pollutants. At the same time, sensors further improve the accuracy and reliability of signals through feedback and calibration mechanisms, as well as signal processing techniques.

In summary, the application of linear displacement sensors in power plant steam turbines achieves high-precision measurement and feedback of valve position through their unique structure and working principle. This not only ensures the safe, efficient, and economical operation of the steam turbine, but also enhances the operational efficiency and stability of the entire power plant.
