MeloAuto-Trusted PLC & DCS Parts Supplier
This 8 mm proximity probe delivers precise shaft vibration and position measurements for critical turbomachinery. It functions as an essential component within the Bently Nevada 3300 XL transducer system for condition monitoring. The probe employs eddy current technology to generate a voltage signal proportional to the gap between its tip and the conductive target surface. Moreover, it fully meets API 670 standards for mechanical configuration, linearity, and thermal stability.

Design and Installation Advantages
This probe features an M10 x 1 metric thread for mounting in metric-standard machine casings. The fully threaded configuration ensures maximum thread engagement for superior mounting stability. Its 34.0 mm overall case length provides a versatile profile for various installation depths. Furthermore, the 1.0 meter total cable length connects directly to a Proximitor sensor without requiring extension cables. This design minimizes signal loss and simplifies overall system wiring.
Measurement Performance
This probe delivers stable and repeatable readings across its 2 mm linear measurement range. The 7.87 V/mm sensitivity ensures precise monitoring of shaft vibration and position. The 3300 XL 8 mm system guarantees complete interchangeability of probes, extension cables, and Proximitor sensors. Consequently, users can replace individual components without system recalibration, significantly reducing maintenance downtime.
Environmental Durability
The probe operates reliably across extreme temperatures from -52°C to +177°C. Its PPS tip and stainless steel case resist harsh industrial chemicals, moisture, and abrasive contaminants. The FEP cable insulation maintains excellent flexibility and signal integrity under demanding conditions. Therefore, this probe suits power generation, oil and gas, and heavy industrial applications requiring dependable machine protection.
