The valve position sensor TD-1-0050-10-01-01 is a LVDT (Linear Variable Differential Transformer) displacement sensor based on the principle of differential inductance. It converts the mechanical quantity of linear movement into an electrical signal to achieve accurate monitoring of the valve position. This sensor is widely used in the oil motor stroke and valve position monitoring of power plant steam turbines, providing reliable data support for the automatic control of steam turbines.

Technical specifications

• Accuracy: nonlinearity is less than 0.5% F.S, ensuring high accuracy of measurement results.

• Excitation voltage: 3Vrms, excitation frequency 2kHz, adaptable to a variety of power supply conditions.

• Operating temperature: -40℃～150℃, able to work stably under the common temperature environment of power plants.

• Output sensitivity: 2.8～230mV/mm, able to provide high-sensitivity displacement signals

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

Product Features

• High-precision measurement: using advanced differential inductance principle, it can accurately detect valve position and provide reliable data for precise control of steam turbines.

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

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

• Strong compatibility: can match various imported transmitters (card boards), with the same technical performance as imported sensors, and can be seamlessly integrated into existing control systems.

• Easy to install: the sensor is calibrated before leaving the factory, and no additional calibration is required during installation, which simplifies the installation process.

Application field

The valve position sensor TD-1-0050-10-01-0 is widely used in oil motor stroke and valve position monitoring of steam turbines in power plants. It can monitor the opening and closing status of the valve in real time, convert mechanical displacement into electrical signals, and transmit them to the control system. This allows operators to precisely control the valve opening of the steam turbine, optimize power generation efficiency, and prevent downtime accidents caused by valve failure.

Installation and Maintenance

The valve position sensor TD-1-0050-10-01-0 has a simple installation process, and its lead wire is well 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.

During maintenance, ensure that the lead wire of the sensor is firmly connected to avoid signal interruption due to looseness. Regularly check the installation position of the sensor to ensure that it has not shifted due to mechanical vibration. In addition, calibrate the sensor regularly to ensure that its measurement accuracy meets the requirements.

In short, the valve position sensor TD-1-0050-10-01-0 has become the preferred equipment for monitoring the oil motor of the steam turbine in the power plant 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.
