Description Reviews

The Bently Nevada 330191-00-33-90-05 is a high-performance 3300 XL 8 mm Extended Temperature Range (ETR) Proximity Probe. Designed for demanding industrial environments, this probe provides reliable, non-contact measurement of static and dynamic distances between the probe tip and a conductive target. It is essential for monitoring radial vibration, axial position, and speed in critical rotating machinery.

Features

Extended Temperature Range (ETR): Engineered to maintain accuracy and integrity under significant thermal stress.
8 mm Tip Diameter: Industry-standard sensing element for consistent eddy current signal generation.
Integrated 9.0 Meter Cable: Reduces the need for intermediate connections, minimizing signal noise and potential failure points in harsh environments.
ClickLoc Connector: Features a tactile locking mechanism to ensure a secure, sealed connection, preventing fluid ingress.
Rugged Construction: Built with a 3/8-24 UNF thread for secure mounting in specialized housings.

Applications

Gas Turbines: Monitoring exhaust vibration, bearing struts, and seal clearance.
Steam Turbines: Measuring thrust position and differential expansion near labyrinth seals.
Centrifugal Compressors: Detecting high-speed shaft vibration and eccentricity.
Hydroelectric Turbines: Tracking generator radial vibration and overall health.
Industrial Motors: Identifying rotor imbalance and bearing abnormalities.

Technical Specifications

Model	330191-00-33-90-05
Probe Type	3300 XL 8 mm ETR Proximity Probe
Thread Size	3/8-24 UNF
Unthreaded Length	0.0 in
Case Length	3.3 in
Cable Length	9.0 meters (29.5 feet)
Agency Approvals	CSA, ATEX, IECEx
Target Material	Standard calibration for AISI 4140 steel

Installation Guidelines

ESD Precautions: Handle the probe with care to prevent electrostatic discharge damage to the internal electronics.
Mounting: Ensure the probe is mounted in a rigid bracket to prevent mechanical resonance. Use the provided lock nuts to secure the 3/8-24 thread.
Gap Setting: The ideal operating gap is typically 1.27 mm (50 mils), corresponding to a -9.0 Vdc output when measured between the SIG and COM terminals of the associated Proximitor sensor.
Cable Routing: Route the integrated 9.0m cable away from high-voltage power lines and sources of high EMI to maintain signal integrity.
Connector Handling: The ClickLoc connector should be tightened by hand until a tactile click is felt; do not use pliers or excessive force.

FAQs

What is the primary function of the 330191-00-33-90-05?

This probe measures the distance between the sensor tip and a conductive target, allowing for the monitoring of vibration, position, and speed in fluid-film bearing machines.

What does the 05 suffix represent?

The 05 suffix indicates that the unit meets specific agency certifications, including CSA, ATEX, and IECEx, making it suitable for hazardous area installations.

Can this probe be used with any shaft material?

The standard calibration is optimized for AISI 4140 steel. If the target material differs, the scale factor must be adjusted accordingly.

How do I verify the probe is installed correctly?

Use a digital voltmeter to measure the output voltage at the Proximitor sensor terminals. A reading of -9.0 Vdc is the standard target for a 1.27 mm (50 mil) gap.
