The Eddy current sensor is the core part of the system. It includes the circuits of oscillation, linear detection, filtering, linear compensation and amplification of the whole sensor system. Together with the extension cable and probe, it forms DWQZ axial displacement turbine sensors of various specifications. According to the diameter specification of the probe, DWQZ Eddy current sensor is divided into three parts:φ 8mm、φ11mm、φ25 mm .There are three specifications. According to the total length of system cable (probe cable length + extension cable length), each specification can be divided into 5M and 9M.
