The displacement sensor TD-1 0-100mm, as a precision displacement converter, is a typical device in the field of industrial automation that monitors linear displacement and converts it into an analog voltage signal. The sensor is exquisitely designed and the main body is made of high-quality stainless steel. This material selection not only gives the sensor excellent corrosion resistance, but also ensures long-term stable working ability under harsh working conditions such as high temperature, humidity or oil pollution. It is very suitable for precise monitoring of the oil motor stroke of steam turbine units. This article will deeply analyze how the TD-1 0-100mm displacement sensor uses LVDT technology to achieve accurate measurement and monitoring of the oil motor stroke of steam turbines under harsh working conditions.

The design of the TD-1 0-100mm displacement sensor fully considers various challenges in practical applications, such as extreme conditions such as high temperature, oil pollution and continuous vibration. It is made of sturdy and durable stainless steel to ensure long-term stable operation in the harsh environment inside the steam turbine. Its internal integrated LVDT component constitutes the basis for the sensor to detect linear displacement, and through the principle of electromagnetic induction, it realizes high-precision measurement of tiny displacements.

In the steam turbine system, the hydraulic motor is a key component for driving the regulating valve and controlling the throttle opening. The precise control of its stroke directly affects the load adjustment and operating efficiency of the steam turbine. The displacement sensor TD-1 0-100mm monitors the displacement changes of the piston or valve stem in real time by being tightly installed on the stroke track of the hydraulic motor. When the piston or valve stem of the hydraulic motor moves according to the working requirements, the position of the iron core changes, which in turn affects the magnetic field distribution around the coil. This change causes a difference in the induced electromotive force generated in the two secondary coils, and this difference value is directly proportional to the displacement of the iron core, which is converted into an analog electrical signal representing the displacement.

These analog signals are standardized to a range of 0-5V or 4-20mA and then sent to the control system. By connecting to the steam turbine control system or PLC (programmable logic controller), the real-time displacement information is quickly processed and used to evaluate the working status of the hydraulic motor to ensure that it remains within the preset safety and efficiency range. Once abnormal displacement is detected, the system can take immediate measures to avoid potential mechanical damage and protect the entire steam turbine unit from unnecessary impact.

Furthermore, the precise displacement data provided by the TD-1 0-100mm displacement sensor is of great significance for optimizing control strategies, improving response speed and overall efficiency. It is not only a passive monitoring tool, but also a “smart eye” that actively maintains the stability and economy of the turbine. By continuously providing accurate travel information, the sensor has become a key technical means to prevent failures, extend equipment life and improve system reliability.
