Eddy Current Sensing Principle

This probe applies eddy current technology to measure shaft displacement. The tip generates a high-frequency magnetic field toward the target surface. Shaft movement then alters field impedance, and the transducer outputs a proportional voltage signal. Meanwhile, the coaxial cable maintains signal fidelity over long routing distances.

Interface and Mounting Details

The 330103-00-08-10-02-00 pairs with 3300 XL extension cables and Proximitor sensors. A miniature coaxial connector guarantees secure, low-noise signal transfer. Furthermore, the 3/8-24 UNF thread enables direct mounting into bearing housings or brackets.

Material and Environmental Factors

Target material choice strongly influences measurement accuracy. A-ISI 4140 steel serves as the standard calibration reference. Therefore, alternative alloys may demand a correction factor. The stainless steel housing resists oil, moisture, and electromagnetic interference. Additionally, the sealed design performs reliably in demanding industrial environments.
