330191-00-16-10-00 | Bently Nevada 3300 XL 8mm ETR Probe

Product Overview

The Bently Nevada 330191-00-16-10-00 is a 3300 XL 8 mm ETR proximity probe designed for reliable vibration and position measurement in rotating machinery. This specific configuration features a 3/8-24 UNF thread, no armor, and a total length of 1.0 meter (3.3 feet). As part of the trusted 3300 XL series, this probe delivers accurate, repeatable measurements essential for predictive maintenance and machine protection.

Engineered with a patented TipLoc molding method, the probe tip and body form a robust bond that withstands harsh industrial environments. The cable incorporates a patented CableLoc design, providing 330 N (75 lbf) pull strength to secure the probe cable and tip firmly. This durability minimizes downtime and reduces the total cost of ownership.

Industry Applications

The 330191-00-16-10-00 is ideal for vibration monitoring on critical rotating equipment such as turbines, compressors, pumps, and motors. Its 8 mm probe size and robust PPS tip encapsulation provide enhanced durability against physical abuse, making it suitable for demanding environments like oil & gas, power generation, and petrochemical plants.

With a 1.0-meter total length, this probe is perfect for installations where the sensor must be mounted close to the measurement point without the need for an extension cable. The 3/8-24 UNF thread ensures a secure and standardized mounting, compatible with many existing brackets and holders.

Installation & Setup Guidance

Proper installation is critical for accurate measurements. Follow these best practices:

Ensure the probe tip is clean and free of debris before installation.

Use the specified torque for the connector (0.565 N•m) to avoid damaging the gold-plated contacts.

Verify the thread engagement does not exceed 0.563 inches to prevent bottoming out.

For one-meter systems, no extension cable is needed—connect directly to the proximitor.

Confirm the supply voltage matches the requirements (-17.5 Vdc to -26 Vdc) to maintain linear range.

Maintenance & Reliability

The 3300 XL probe is designed for long-term reliability. The patented TipLoc and CableLoc designs reduce the risk of mechanical failure, while the stainless steel case resists corrosion. To maximize service life:

Periodically inspect the probe cable for cuts or abrasions, especially in high-vibration areas.

Check the mounting tightness during routine maintenance to prevent loosening.

If the probe is exposed to oil or chemicals, consider the optional FluidLoc cable option to prevent liquid ingress.

Follow the manufacturer's guidelines for periodic testing to verify proper operation.
