Component Structure and Interface
Each assembly contains a probe tip, cable, and coaxial connector. The pairs with 3300 XL drivers for signal demodulation. Moreover, the stainless steel body resists corrosion and mechanical wear. The shielded cable minimises electrical noise from nearby drives and motors.
Power and Signal Conditioning
This probe holds no internal energy storage elements. Instead, it depends on an external proximity driver for excitation. The driver supplies -24 VDC and processes the returned signal. As a result, the system outputs voltage proportional to shaft position.
Mounting and Calibration Notes
Technicians mount the probe through a threaded hole or bracket. Target material selection matters, because different alloys alter sensitivity readings. Therefore, always confirm calibration against the actual shaft alloy. Additionally, keep cable runs short to limit signal attenuation.
