Performance Advantages and Asset Health
This proximity probe excels in demanding environments like power stations, oil refineries, and chemical processing plants. The sensor employs a polyphenylene sulfide (PPS) tip that resists chemical degradation and moisture ingress, maintaining measurement integrity in harsh conditions. Furthermore, the 3300 XL series offers superior temperature stability and interchangeability compared to previous sensor generations. By adhering to API 670 standards, this probe ensures accurate monitoring for:
- Fluid-film bearing performance in steam and gas turbines
- Axial displacement in high-pressure centrifugal compressors
- Shaft eccentricity and thermal expansion diagnostics
- Speed and phase reference via Keyphasor technology
Installation and System Configuration
Technicians install the 330101-00-50-20-02-CN using its 3/8-24 UNF forward-mount threads to achieve the correct gap voltage—typically set at -10.0 Vdc. To complete a standard 5.0-meter or 9.0-meter measurement loop, the user must pair this 2.0-meter probe lead with the corresponding 3.0-meter or 7.0-meter 3300 XL extension cable. The included connector protector (02 option) seals the coaxial link against lubricating oils and environmental debris, which effectively eliminates signal interference and ground loops. This robust installation strategy guarantees a clean, actionable data stream for sophisticated rotor dynamics analysis.
