Displacement sensor 3000TD-15-01 belongs to the TD series LVDT (differential transformer) displacement sensor. It is based on the principle of electromagnetic induction and converts linear displacement into electrical signal output through the position change of the movable iron core in the differential transformer. This sensor has good dynamic characteristics and can achieve high-speed online detection. It has a simple structure and small size, which is easy to install and maintain.

Technical specifications

• Linear range: 0~150mm, which can meet the needs of steam turbine oil motor stroke monitoring.

• Non-linearity: not more than 0.5% F·S, ensuring high accuracy of measurement results.

• Primary impedance: not less than 500Ω (oscillation frequency is 3kHz).

• Working temperature: ordinary type -40℃~+150℃, which can work stably under the temperature environment commonly seen in power plants.

• Temperature drift coefficient: less than 0.03% F·S/℃, ensuring that the measurement accuracy is not affected when the temperature changes.

• Excitation voltage: 3Vrms (1~5Vrms), excitation frequency: 2.5kHz (400Hz~5kHz), adaptable to various power supply conditions.

• Lead wires: six Teflon insulated sheathed wires, with stainless steel sheathed hoses outside, providing good electrical insulation and mechanical protection.

• Vibration tolerance: 20g (up to 2kHz), able to withstand the vibration generated during the operation of the turbine.

Product Features

• High-precision measurement: using advanced measurement principles, it can accurately detect linear displacement and provide reliable data for the precise control of the turbine oil motor.

• Stable performance: in harsh working environments, such as high temperature, vibration, etc., it can still maintain stable measurement performance to ensure the long-term stable operation of the turbine.

• Long-life design: sturdy structure, long service life, reducing maintenance and replacement costs.

• Strong compatibility: It can match various imported transmitters (card boards), and its technical performance is the same as that of imported sensors, and it can be seamlessly integrated into the existing control system.

Application field

The displacement sensor 3000TD-15-01 is widely used in the monitoring of the stroke of the oil motor of the steam turbine in power plants. It can monitor the stroke changes of the oil motor in real time, convert the mechanical displacement into an electrical signal, and transmit it to the control system. This allows operators to accurately control the valve opening of the steam turbine, optimize the power generation efficiency, and prevent shutdown accidents caused by valve failure.

Installation and maintenance

The installation process of the displacement sensor 3000TD-15-01 is simple, and its lead wire is reasonably designed for easy connection. In daily maintenance, you only need to regularly check the connection of the lead wire and the appearance of the sensor to ensure that it is in good working condition. Due to its resistance to vibration and high temperature, the risk of failure caused by environmental factors is reduced.

In short, the displacement sensor 3000TD-15-01 has become the preferred equipment for monitoring the oil motor of the steam turbine in power plants with its high precision, high stability and long life. It can not only improve the operating efficiency of the steam turbine, but also enhance the reliability and safety of the system.
