During the operation of the turbine in the power plant, axial displacement and vibration will occur due to factors such as water flow impact, mechanical wear, and load changes. In order to monitor these parameters in real time and ensure the normal operation of the turbine, the turbine axial displacement vibration sensor XS12J3Y is particularly important.

Working Principle

The XS12J3Y turbine axial displacement vibration sensor adopts advanced sensing technology, and its core principle combines the Hall effect and vibration measurement technology. The Hall effect means that when the magnetic field acts on the Hall element, a potential difference (Hall voltage) will be generated on both sides of it. This voltage is perpendicular to the magnetic field strength and current direction. In the XS12J3Y sensor, when the turbine undergoes axial displacement or vibration, these mechanical changes will be converted into changes in the magnetic field, and then converted into electrical signals through the Hall element.

Specifically, the XS12J3Y sensor integrates Hall elements, amplifier circuits, shaping circuits, and output circuits. When the turbine rotor or other components are displaced or vibrated, the magnetic field around the sensor will change. This magnetic field change is captured by the Hall element and converted into a weak electrical signal. Subsequently, the built-in amplifier circuit amplifies the signal to improve the signal strength and measurement accuracy. The shaping circuit converts the amplified signal into a standard rectangular pulse signal for subsequent signal processing and analysis. Finally, the output circuit outputs the processed signal to the control system or display instrument to achieve real-time monitoring of the axial displacement and vibration of the turbine.
