The LVDT Position Sensor DET400A is an LVDT (Linear Variable Differential Transformer) hydraulic motor travel sensor, based on the principle of differential inductance. It can convert the mechanical quantity of linear motion into electrical quantity, achieving automatic monitoring and control of displacement. This type of sensor has advantages such as high temperature resistance, small size, high accuracy, stable performance, reliable operation, and long service life, thus playing an important role in steam turbine control systems.

To ensure the stability and accuracy of LVDT Position Sensor DET400A, necessary adjustments need to be made. These adjustments typically include two steps: zero calibration and calibration. Zeroing refers to zeroing the output of a potential shifter (such as LVDT) without external force on the sensor to eliminate installation errors and initial offsets. Calibration criteria refer to comparing the output signal of a sensor with a standard value and fine-tuning it based on the comparison results. These adjustments need to be made by professional technicians using professional calibration equipment and tools to ensure accuracy and reliability.
