Sensor HTD-150-6H is a high-performance displacement sensor designed for measuring the displacement of the actuator of steam turbine units. It adopts advanced LVDT (Linear Variable Differential Transformer) technology and realizes accurate displacement measurement through the principle of differential inductance, providing reliable guarantee for the stable operation of steam turbine units.

Product Features

1. High-precision measurement: The HTD-150-6H sensor has extremely high measurement accuracy, and its linear range can reach ±10~±800mm, which meets the needs of steam turbine units of different specifications. Its accuracy is as high as 0.25%, which can accurately reflect the slight displacement changes of the actuator and ensure the accuracy of the measurement results.

2. High reliability: The housing of the sensor is made of stainless steel, with the characteristics of simple structure, maintenance-free and durable. It has strong anti-interference ability and can work stably for a long time in harsh industrial environments to ensure the continuity and reliability of measurement data.

3. Versatility: The HTD-150-6H sensor is combined with the DYX-U actuator monitor to realize the functions of remote indication, alarm and constant current output of valve position travel. At the same time, it also has two indication modes: local and remote, to meet the needs of different application scenarios.

Working principle

The sensor HTD-150-6H contains three coils: a fixed coil and two measuring coils. The measuring coils are located on both sides of the fixed coil to form a pair of differential coils. When the external measuring rod (connected to the actuator) is displaced, the induction of the coil inside the sensor will be changed, thereby generating a differential voltage signal. This signal is proportional to the displacement of the measuring rod and is converted into a standard output signal by the signal processing circuit for use by the control system.

Application scenario

The HTD-150-6H sensor is widely used in displacement measurement and automatic control of large rotating machinery such as steam turbines, water turbines, blowers, compressors, etc. in the power, petroleum, chemical, metallurgy and other industries. Its high precision, high reliability and versatility make it an ideal choice for displacement measurement of actuators in steam turbine units.

In short, the sensor HTD-150-6H plays an important role in the field of displacement measurement of steam turbine actuators with its excellent performance and wide application scenarios.
