Eddy Current Measurement Principle

This probe uses eddy current technology to detect shaft displacement. The tip emits a high-frequency magnetic field toward the target surface. Shaft movement then changes field impedance, and the transducer produces a proportional voltage signal. Meanwhile, the coaxial cable preserves signal integrity across extended routing paths.

Interface and Mounting Details

The 330103-00-09-05-02-00 connects with 3300 XL extension cables and Proximitor sensors. A miniature coaxial connector ensures secure, low-noise signal transmission. Furthermore, the 3/8-24 UNF thread supports direct mounting into bearing housings or brackets.

Material and Environmental Considerations

Target material selection directly affects measurement accuracy. A-ISI 4140 steel serves as the standard calibration reference. Therefore, alternative alloys may require a correction factor. The stainless steel housing resists oil, moisture, and electromagnetic interference. Additionally, the sealed construction performs reliably in harsh industrial environments.
