Product Overview
The Bently Nevada 330101-00-40-10-02-BR is a 3300 XL 8 mm Proximity Probe for non-contact measurement of conductive targets in rotating machinery. It is installed near the monitored shaft or other suitable target and operates as the machine-side sensing element of a complete eddy-current proximity measurement channel.
In a typical machinery protection installation, the probe is mounted at a bearing or machine measurement location while the associated Proximitor Sensor and monitoring electronics are positioned elsewhere. The probe continuously responds to changes in the distance between its sensing tip and the target surface. This makes it suitable for applications where shaft movement, vibration, or position needs to be observed without physically contacting the rotating component.
The probe is normally used together with a compatible extension cable and Proximitor Sensor. Correct matching of these components is important because the proximity probe is part of an integrated measurement chain. During installation or replacement, the probe configuration, connection components, mounting arrangement, and target relationship should all be verified.

Working Principle
The 330101-00-40-10-02-BR works as the sensing element in an eddy-current proximity measurement system. The probe does not physically touch the monitored shaft. Instead, its sensing field interacts with the conductive target and changes according to the probe-to-target relationship.
1. Electrical excitation
The compatible Proximitor Sensor supplies the electrical excitation required for operation of the probe. The probe and Proximitor Sensor function together as the measurement front end.
2. Target interaction
The probe is positioned near a conductive shaft or another appropriate target. The electromagnetic field generated around the probe tip interacts with the target surface.
3. Movement detection
When the shaft moves relative to the probe, the electrical response of the sensing circuit changes. This change corresponds to the relative movement between the probe and target.
4. Signal conditioning
The associated Proximitor Sensor conditions the probe response into a signal that can be used by the connected monitoring system. The resulting measurement can support vibration or shaft-position monitoring depending on the configured application.
5. Continuous monitoring
Once properly installed, the probe can remain in position while the machinery operates. The monitoring system can use the resulting proximity signal to observe machine behavior and identify changes that may require further inspection.
Role in a 3300 XL Proximity Monitoring Architecture
The 330101-00-40-10-02-BR occupies the sensing layer of the 3300 XL proximity measurement architecture. It establishes the physical measurement point at the machine and works with the extension cable, Proximitor Sensor, and downstream monitoring equipment.
| Architecture Layer | Component / Function | Role |
|---|---|---|
| Machinery | Rotating Shaft / Conductive Target | Provides the target for proximity measurement |
| Sensing Layer | 3300 XL 8 mm Proximity Probe | Detects relative movement between probe and target |
| Connection Layer | Compatible Extension Cable | Connects the probe with the Proximitor Sensor |
| Interface Layer | 3300 XL Proximitor Sensor | Excites the probe and conditions the measurement |
| Monitoring Layer | Machinery Monitoring / Protection System | Receives and evaluates the measurement |
Industrial Applications
| Application | Typical Use |
|---|---|
| Steam Turbines | Shaft vibration and position monitoring |
| Gas Turbines | Non-contact monitoring of rotating shaft movement |
| Compressors | Continuous shaft-related condition monitoring |
| Pumps | Monitoring rotating shaft behavior |
| Motors | Non-contact observation of shaft movement |
| Gearboxes | Supporting rotating equipment condition monitoring |
| Industrial Machinery | Proximity measurement within machinery protection systems |
Installation and Maintenance
- Verify the complete model number – Confirm the exact 330101-00-40-10-02-BR configuration before installation or replacement.
- Confirm system compatibility – Check that the probe is matched with the appropriate Proximitor Sensor and extension cable.
- Inspect the sensing tip – Ensure that the probe tip is clean and free from visible damage before installation.
- Check the cable assembly – Inspect the integral cable and termination for cuts, crushing, excessive bending, or other physical damage.
- Prepare the mounting point – Clean and inspect the mounting location before securing the probe.
- Set the probe position correctly – Establish the required probe-to-target relationship according to the applicable installation procedure.
- Prevent shaft contact – Maintain sufficient clearance so the probe cannot mechanically contact the rotating target during operation.
- Secure the probe mechanically – Ensure the probe remains fixed and cannot shift because of machine vibration.
- Route the cable safely – Keep the cable away from sharp edges, high-temperature areas, moving machinery, and potential pinch points.
- Inspect connections after maintenance – Check the complete probe connection whenever work is performed on the monitoring channel.
- Troubleshoot the complete channel – If readings become abnormal, inspect probe positioning, target condition, cable integrity, and the associated electronics together.
- Use the correct replacement configuration – Replace a damaged probe with the appropriate 3300 XL configuration rather than selecting a similar-looking probe solely by physical dimensions.

Technical FAQs
What is the Bently Nevada 330101-00-40-10-02-BR used for?
It is a 3300 XL 8 mm proximity probe used for non-contact measurement of conductive targets in rotating machinery. In a complete monitoring channel, the measurement can support shaft vibration and position monitoring.
How does the probe detect shaft movement without touching the shaft?
The probe uses an eddy-current sensing principle. Its electromagnetic field interacts with the conductive target, and changes in the distance between the probe and target produce corresponding changes in the electrical response.
What components are required for a complete proximity measurement channel?
The probe normally operates with a compatible extension cable and Proximitor Sensor. The conditioned output is then connected to the appropriate machinery monitoring or protection equipment.
What should be checked when replacing this proximity probe?
Verify the complete probe part number and compatibility with the existing Proximitor Sensor and cable. The probe mounting location, probe-to-target relationship, cable condition, and final monitoring signal should also be checked during commissioning.
