Bently Nevada 330101-00-57-10-02-05 3300 XL 8mm Proximity Probes

The Bently Nevada 330101-00-57-10-02-05 is a precision-engineered proximity probe from the 3300 XL 8mm series, designed to deliver accurate, real-time monitoring of shaft vibration and position in critical rotating machinery. Engineered with durability, stability, and high fidelity in mind, this probe is tailored for use in hostile industrial environments where precise measurements are critical for equipment reliability and predictive maintenance.

With a 57 mm probe case length and 1 meter extension cable, this specific configuration offers versatile mounting capabilities, particularly suited for installations with moderate reach requirements and longer sensor-to-monitor distances. It is part of a complete proximity transducer system that includes the probe, extension cable, and Proximitor® sensor.

The 3300 XL series is compliant with API 670, the gold standard for machinery protection systems. This model is widely used in industries such as oil & gas, petrochemical, power generation, and marine engineering, where monitoring rotating assets is non-negotiable.

FAQs

1. What distinguishes the 57 mm probe length from other models?

   It offers a balanced design for mid-range installations, ensuring reach without excess protrusion into machine housings.

2. Is the 1 meter extension cable part of the total system length or additional?

   It is part of the system design, giving a combined connection length when paired with the integral probe cable and Proximitor® sensor.

3. Can this model be used in offshore oil platforms?

   Yes, the sealed stainless-steel construction makes it ideal for offshore environments exposed to saltwater mist and vibration.

4. What are the risks of using non-API-compliant sensors in critical rotating machinery?

   Non-compliant sensors may produce inaccurate readings, lack reliability, or fail under extreme conditions—leading to undetected mechanical faults.

5. Does this probe support dual-channel monitoring systems?

   It is designed for single-channel proximity measurements, but can be deployed in redundant or dual-channel configurations using multiple probes.

6. What kind of extension cables are compatible with this model?

   Only Bently Nevada-certified coaxial extension cables (e.g., 330180 series) are guaranteed to maintain signal fidelity over distance.

7. Is vibration signal attenuation a concern over 10 meters?

   Not with the 3300 XL system. The probe, extension cable, and Proximitor® sensor are impedance-matched to preserve accuracy.

8. Can this probe be field-serviced or replaced without recalibrating the system?

   Yes. It’s factory-calibrated and field-replaceable. No recalibration is needed if paired with the matching extension cable and Proximitor®.

9. What is the expected operational lifespan of this model?

   Under standard conditions, these probes commonly exceed 5–7 years of continuous service without failure.

10. Can the probe be mounted in high-vibration zones near rotating couplings?

    Absolutely. The ClickLoc™ connector and robust body ensure signal reliability even in high-vibration environments.
