In an environment where high precision and stability are paramount, such as in steam turbines, the TDZ-1-100 linear displacement sensor stands out due to its exceptional accuracy, interference resistance, and long-term stability. This article will delve into the advantages of the TDZ-1-100 sensor in steam turbine applications, explaining why it is well-suited for this demanding task.

High Precision: A Millimeter’s Difference, a Mile’s Error

Steam turbines, being the core equipment of power plants, have their operational status directly linked to the stable supply of electricity and production safety. Among the numerous critical components of a steam turbine, the control of main and regulating steam valves is of utmost importance. The TDZ-1-100 displacement sensor demonstrates extraordinary high-precision characteristics in this context. Its measurement error typically remains within ±0.1% of full scale, which means that in a 100mm range, the measurement error does not exceed 0.1mm—a significant advantage for turbine control requiring micron-level precision.

The TDZ-1-100 sensor employs LVDT (Linear Variable Differential Transformer) technology, a measurement method based on the principle of electromagnetic induction, capable of converting physical displacement into an electrical signal. A standout feature of LVDT technology is its virtually linear output characteristic, indicating that within the effective measuring range of the sensor, the output signal and displacement change exhibit an almost perfect linear relationship, thus ensuring high precision and consistency in measurements.

Strong Interference Resistance: Stable Output, Unaffected by External Disturbances

Within steam turbines, there exists a complex electromagnetic environment, including but not limited to electromagnetic fields generated by motors, inverters, and high-voltage lines. These electromagnetic interferences can lead to distortion of the measurement signal, potentially impacting sensor performance. However, the TDZ-1-100 displacement sensor has been designed with this challenge in mind, incorporating shielding techniques and signal filtering to effectively reduce the impact of external electromagnetic interference on measurement results.

Displacement sensors typically use differential signal transmission at the output end, a method capable of resisting common-mode interference, ensuring the stability and accuracy of signals over long-distance transmissions. Furthermore, the internal circuit design of the sensor has been optimized to enhance its interference resistance, guaranteeing reliable and stable measurement data even under harsh industrial conditions.

Long-Term Stability: Timeless, Precision Remains

For equipment like steam turbines, which operate continuously for long periods, the long-term stability of sensors is a decisive factor in determining their suitability for application. The TDZ-1-100 displacement sensor uses high-quality materials and precise manufacturing processes to ensure stability and reliability during extended use. The coil and magnetic core undergo special treatments, enabling them to withstand extreme conditions such as high temperatures, pressures, and vibrations, avoiding measurement errors caused by material fatigue or aging.

Moreover, the TDZ-1-100 displacement sensor takes thermal expansion and mechanical stress into account in its design, through reasonable structural layouts and temperature compensation techniques, ensuring measurement accuracy under different temperature and load conditions. This means that even during frequent starts, stops, and long-term operations of the steam turbine, the sensor maintains its high level of accuracy without being affected by environmental changes.
