Operational Reliability and Industrial Benefits

This reverse mount 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. The reverse mount design facilitates installation from the inside of the machine housing, making it ideal for applications with restricted external access. 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 Integration

Maintenance technicians utilize the 3/8-24 UNF threads to secure the 330105-02-12-15-02-CN into specialized brackets, typically gapping it at -10.0 Vdc for optimal linearity. To complete a standard 5.0-meter or 9.0-meter measurement loop, the user must pair this 1.5-meter probe lead with the corresponding 3.5-meter or 7.5-meter 3300 XL extension cable. The included connector protector (02 option) seals the coaxial ClickLoc 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.
