Bently Nevada 330171-00-08-90-01-05 3300 5 mm Proximity Probes

The Bently Nevada 330171-00-08-90-01-05 is part of the trusted 3300 XL series of proximity transducer systems, widely used in machinery condition monitoring and protection systems. This specific model is a 5 mm reverse mount proximity probe, designed to deliver high-precision, non-contact measurements of shaft vibration and position in rotating machinery. Its reverse mount configuration allows installation from the rear side of the mounting surface, ideal for applications where space constraints prevent traditional forward installation.

As with other components in the 3300 XL series, this proximity probe is engineered for long-term durability and performance in demanding industrial environments. The probe integrates seamlessly with the 3300 XL Proximitor® Sensor and is compliant with API 670 standards, making it an excellent choice for critical monitoring in the oil & gas, petrochemical, and power generation sectors.

Frequently Asked Questions (FAQ)

1. What is the primary purpose of this 330171 probe?

   It measures shaft vibration and relative position using non-contact eddy current sensing technology.

2. Why is it called a ‘reverse mount’ probe?

   The probe is designed to be installed from behind the mounting surface, providing access flexibility in tight spaces.

3. What proximity measurement range does it support?

   The standard linear range is up to 2 mm (80 mils).

4. Is it compatible with other Bently Nevada systems?

   Yes, it is compatible with the 3300 XL Proximitor Sensor and extension cables.

5. What’s the significance of the “-08” in the part number?

   It denotes an 8-foot integral cable attached to the probe.

6. Can the probe operate in high EMI environments?

   Absolutely. It is shielded with a stainless-steel overbraid for excellent EMI resistance.

7. Is this sensor suitable for hazardous environments?

   While it has high resistance to harsh conditions, certification for hazardous locations depends on the overall system installation.

8. How is the probe secured during installation?

   It uses standard threaded mounts and locking nuts; torque specifications are available in the installation manual.

9. What is the difference between this and the 8 mm probe version?

   The 5 mm probe is for smaller shaft diameters or tight spaces, while 8 mm probes are used where more linear range is needed.

10. How often should the probe be calibrated or checked?

    Annual verification is recommended, though the rugged design supports multi-year uninterrupted service.
