Bently Nevada 330191-00-70-05-00 | 3300 XL 8 mm ETR Proximity Probe

The 330191-00-70-05-00 is a Bently Nevada 3300 XL 8 mm Extended Temperature Range (ETR) proximity probe. It provides non-contact displacement sensing for rotating machinery.

This configuration uses a 3/8-24 UNF mounting thread, a 7-inch overall case, and a 0.5-meter probe cable. Its unarmored construction suits installations that require compact probe mounting and a defined cable route.

The 3300 XL 8 mm design uses a molded PPS probe tip and a robust stainless-steel case. TipLoc and CableLoc construction improve the mechanical connection between the probe tip, body, and cable.

Scale factor / sensitivity	Use the matched system calibration data. The supplied product information does not state a numeric value for this specific ordering configuration.
Linearity and resolution	Confirm using the applicable system specification and monitor channel configuration

Important: Do not apply the power-supply figures as standalone probe power requirements. They describe the associated measurement electronics and installation conditions.

Temperature Classification | Select for the Actual Environment

The supplied temperature schedule lists different ambient limits by temperature classification. The applicable rating depends on the approved installation and complete system.

Classification	Probe ambient temperature range for EPL Ga/Gc
T1	-55°C to +232°C
T2	-55°C to +177°C
T3	-55°C to +120°C
T4	-55°C to +80°C
T5	-55°C to +40°C

The supplied EPL Dc schedule lists separate maximum surface-temperature classifications. Verify the exact marking and certification documentation before applying these values.

Selection guidance: Check the temperature at the probe installation point, not only the machinery's general operating temperature. Confirm the cable, connector, Proximitor Sensor, and hazardous-area approvals also meet the application limits.

Installation | Mounting and Cable Handling

Confirm the 3/8-24 UNF mounting thread and available probe clearance.
Keep thread engagement within the specified 0.563-inch maximum.
Set the probe gap according to the matched Proximitor Sensor instructions.
Route the cable away from moving parts, sharp edges, and hot surfaces.
Prevent connector strain. Observe the specified maximum connector torque.
Use the correct extension cable and monitor configuration for the complete electrical length.
Follow the manufacturer's grounding, shielding, and hazardous-area installation instructions.

Do not pressure-test the probe without an approved procedure. The manufacturer states that probes are not pressure-tested before shipment.

Compatibility | Replacement and System Integration

The 3300 XL 8 mm ETR probe requires compatible Bently Nevada proximity monitoring components. Verify the complete system before ordering a replacement.

Proximitor Sensor: Confirm the sensor supports the 3300 XL 8 mm ETR probe.
Extension cable: Match the cable type and total electrical length to the existing installation.
Monitor: Verify input compatibility, channel settings, and calibration requirements.
Mechanical mounting: Match the thread, case length, and installation clearance.
Hazardous-area installation: Confirm approval markings and the required barriers or isolators.

A similar probe family name does not guarantee an interchangeable installation. Confirm the complete part number and system configuration before replacement.

Alternative Selection | Compare the Installed Configuration

Review the linked alternative before choosing a replacement.

Selection item	Requested model	Alternative model
Part number	330191-00-70-05-00	330191-00-08-15-05
Product family	3300 XL 8 mm ETR	3300 XL ETR probe
Thread	3/8-24 UNF	Verify against the complete manufacturer configuration
Case length	7 in	Verify the alternative's dimensional option
Probe length	0.5 m	Verify the alternative's total length option
Approval option	00: approval not required	Verify the alternative's approval markings

Technical recommendation: The linked alternative has a different suffix configuration. Do not treat it as a drop-in replacement without checking its dimensions, cable length, connector arrangement, and approvals.

For a maintenance replacement, use the original probe label and installation drawing as the primary references. If the installed dimensions or cable route differ, confirm the mechanical fit before ordering.

Typical Equipment and Applications

Steam turbines: Radial shaft vibration and displacement monitoring.
Gas turbines: Shaft movement monitoring within compatible machinery protection systems.
Compressors: Non-contact shaft measurement for vibration monitoring.
Centrifugal pumps: Shaft vibration and position measurement where the target geometry supports proximity sensing.
Industrial rotating equipment: Condition monitoring in installations that require the specified ETR probe configuration.

Global PLC Spare HUB's Insight | Diagnostic Practice

When a proximity channel behaves unexpectedly, check the probe installation and measurement chain before changing monitor settings.

Observed condition	Recommended diagnostic checks
Gap voltage differs from the expected value	Inspect probe clearance, mounting position, target surface, and sensor compatibility.
Vibration signal becomes intermittent	Inspect the connector, cable strain, shielding, and possible insulation damage.
Readings change after a probe replacement	Compare the part numbers, probe lengths, extension cable, calibration, and target geometry.
Unexpected signal behavior at elevated temperature	Verify the actual probe temperature, cable rating, connector condition, and system temperature limits.
Unusual vibration trend without a clear mechanical change	Review baseline data and check installation integrity before attributing the trend to machinery deterioration.

Field example: A turbine channel shows a different vibration level after maintenance. An engineer should first verify the installed gap and probe model. The engineer should then inspect cable connections and compare the channel's calibration. This process separates installation changes from possible machinery faults.

These diagnostic steps support field troubleshooting. They do not replace site procedures, alarm limits, or manufacturer-approved machinery protection practices.

Certification and Ordering Notes

The requested suffix 00 identifies an agency approval option that is not required.
Do not assume this exact configuration has approval for a classified location.
Check the delivered product markings and certificates for the intended installation.
Confirm whether barriers or isolators are required by the system design.
Verify pressure-seal requirements separately. The probe's Viton® O-ring does not establish a pressure-test certificate.

Frequently Asked Questions

1. What does ETR mean for probe selection?

ETR identifies the extended-temperature-range probe configuration. Check the applicable temperature classification and complete system ratings. Do not select solely by the ETR label.

2. Does the 0.5-meter probe cable eliminate the need for an extension cable?

Not necessarily. The correct cable arrangement depends on the complete 3300 XL system and required electrical length. Confirm the matched Proximitor Sensor and extension cable configuration.

3. Can I install this probe in a high-temperature turbine casing?

First establish the actual probe ambient temperature and required temperature classification. Then verify the probe, cable, connector, sensor, and installation approvals. The application's hottest point determines the necessary rating.

4. What information should I provide when requesting a replacement quotation?

Provide the complete probe part number, installed thread and case dimensions, cable length, connector type, and Proximitor Sensor model. Include the temperature and hazardous-area requirements when applicable.

5. How can I distinguish a probe fault from a monitor-channel problem?

Check the probe gap, cable continuity, connector condition, and sensor compatibility first. Compare the channel with its commissioning baseline. Use approved test procedures to isolate components without compromising machinery protection.
