Technical Description
The 330105-02-12-05-02-00 is a reverse-mount proximity probe from Bently Nevada’s 3300 XL series, specifically engineered for shaft radial vibration and axial position measurement in space-constrained machinery. Unlike standard probes that pass through the machine casing, this reverse-mount design allows the probe to be installed from the inside of the bearing housing, facing outward. It is ideal for applications in smaller centrifugal pumps, gearboxes, or specialized turbomachinery. The probe uses high-performance eddy-current technology to ensure precise, linear voltage outputs, even in environments filled with lubricants or steam.

Operational Application
The 330105-02-12-05-02-00 is specifically designed for condition monitoring in systems where the probe must be mounted internally within the bearing cap or support housing. By enabling non-contact measurement of shaft dynamics, it provides real-time data on critical machine health parameters, such as rotor vibration amplitude, shaft centerline position, and bearing clearance degradation. This is essential for predictive maintenance, allowing engineers to identify issues like misalignment or rotor instability before they lead to unplanned downtime or system failure.
Frequently Asked Questions
What is the primary difference between the 330105 and 330104 models?
The 330105 is designed for reverse mounting, allowing for installation from the inside of a bearing housing, while the 330104 is intended for standard through-case mounting. Although both probes have similar internal electrical characteristics, the 330105 has a different case geometry optimized for reverse-mount applications.
Can this probe be used in hazardous area applications?
The 00 suffix indicates that this specific probe does not have approvals for hazardous areas. For applications that require ATEX, IECEx, or CSA certification for explosive atmospheres, an alternate model with the appropriate certifications should be selected.
Is the 0.5-meter cable length sufficient for most installations?
The 0.5-meter cable length is typically adequate for installations where the Proximitor sensor is positioned in close proximity to the probe, such as inside a common terminal housing or specialized equipment junction box. For longer distances, a longer cable length may be needed.
