Products Description
Bently Nevada 330105-02-12-05-02-00 3300 XL 8 mm Reverse Mount Probes
The 330105-02-12-05-02-00 is a precision displacement sensor engineered for installation in locations where standard probe orientations are physically unfeasible. Its 8 mm probe tip provides a direct physical mapping of shaft movement, translating mechanical motion into an analog electrical signal for downstream measurement and analysis.
The reverse mount design enables operation in tight bearing housings, compact casings, or inverted machine geometries, where conventional probes cannot fit, while preserving the integrity of the signal.
With over 50 million in inventory, PLC EXPORT delivers only brand-new, authentic components- ready to ship,
rigorously tested, and backed by professional technical support.

Functional Role / System Position
This probe forms the mechanical-electrical interface of a shaft measurement loop:
Rotating Shaft → Reverse Mount Probe → Signal Conditioning → Monitoring Electronics → Data Acquisition / Control
It does not perform computation; rather, it provides a stable reference signal. Any inaccuracy or misalignment at this stage propagates through the monitoring system, making the probe's mechanical and electromagnetic behavior critical to overall measurement fidelity.
Key Features / Functional Capabilities
▪ Reverse-mount orientation for constrained installation scenarios
▪ 8 mm probe tip designed for consistent signal delivery in tight spaces
▪ Non-contact eddy current technology minimizes wear and mechanical degradation
▪ Controlled impedance characteristics ensure linear response under vibration
▪ Robust construction tolerates oil, dust, and thermal variation
▪ Directly compatible with 3300 XL Proximitor modules
▪ Reliable performance under long-term continuous operation
Application Areas / Typical Use Cases
- Displacement monitoring in compact turbines, compressors, and motors
- Installation in inverted or limited-access bearing housings
- Integration where traditional probe angles are obstructed by mechanical design
- Replacement of aging or misaligned probes in legacy 3300 XL systems
- Situations where consistent analog measurement is needed despite constrained geometry

Installation / Handling
Correct installation requires precise tip-to-shaft alignment and cable routing that avoids mechanical strain or electromagnetic interference. The inverted configuration demands extra attention to mounting orientation, ensuring linear signal characteristics. After mechanical placement, verify the analog output through the conditioning module before commissioning the system.
Advantages / Value Highlights
By adapting to restricted or inverted mounting positions, the 330105-02-12-05-02-00 allows monitoring in areas previously inaccessible to standard probes. Its stable, non-contact sensing minimizes mechanical wear while delivering a consistent analog signal. This combination ensures measurement integrity in complex industrial installations, supporting accurate system interpretation.

Common problems
Q1: What is the benefit of the reverse mount configuration?
It allows the probe to be installed in spaces where conventional orientation is impossible, without compromising signal quality.
Q2: Does reverse mounting affect measurement accuracy?
No, the probe's design preserves linear signal output regardless of orientation.
Q3: In what type of machinery is this probe commonly installed?
Compact turbines, compressors, pumps, and motors where shaft access is limited.
Q4: How critical is alignment during installation?
Proper alignment is essential; misalignment can introduce measurement errors in downstream monitoring systems.
Q5: Can this probe operate continuously under industrial conditions?
Yes, it is designed for uninterrupted operation under vibration, temperature fluctuations, and oil exposure.
