The Bently Nevada 330703-000-060-90-02-00 operates as a high-precision non-contacting sensor. This 11mm probe measures the physical gap between the sensor tip and a target shaft. It primarily tracks axial position, thrust displacement, and differential expansion in large rotating assets. The 11mm series offers a significantly wider linear range than standard 8mm probes. Consequently, it excels in monitoring thermal growth in steam turbines.

Application and System Compatibility
Industrial facilities use this probe for critical machinery protection and diagnostic analysis. It replaces older 7200-series 11mm sensors during system modernization projects. The probe integrates seamlessly with the Bently Nevada 3500 and 3701 monitoring racks. Common uses include monitoring rod drop in reciprocating compressors. It also serves as a high-reliability Keyphasor for speed and phase measurements.
Installation and Compliance Benefits
The 330703-000-060-90-02-00 configuration adheres strictly to API 670 standards. This alignment ensures the highest level of machinery safety and reliability. The extended cable length allows for remote Proximitor mounting away from extreme heat. Meanwhile, the specialized tip material prevents signal drift during long-term operation. This probe provides the high-fidelity data necessary for advanced predictive maintenance programs.
