Operating 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 changes field impedance, and the transducer outputs a proportional voltage signal. Meanwhile, the coaxial cable preserves signal quality across extended routing paths.

Compatibility and Mounting

The 330103-00-09-10-02-CN works with 3300 XL extension cables and Proximitor sensors. A standard miniature coaxial connector ensures reliable mating. Furthermore, the 3/8-24 UNF thread allows direct installation into bearing housings or mounting brackets.

Environmental and Material Notes

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 suits harsh industrial environments.
