LVDT sensor TDZ-1-50

Short Description:

LVDT sensor TDZ-1-50 is a high-precision displacement sensor designed for the stroke of high-speed oil motors in steam turbines. The sensor is based on the principle of electromagnetic induction and measures linear displacement by generating a changing signal when the iron core moves in the coil. Its core components include a set of primary coils, secondary coils, and moving iron cores. When the primary coil is connected to the excitation signal, the generated magnetic field will cause the two secondary coils to generate an induced electromotive force. Since the secondary coils are connected in reverse series, the change in the position of the iron core will cause the output voltage of the secondary coil to change, forming a differential output signal. After processing, this signal can accurately reflect the displacement of the iron core and achieve high-precision displacement measurement.
