Frequently Asked Questions (FAQs) 

1. How does the 330101-00-55-10-02-05 proximity probe contribute to rotating machinery protection?

   It detects real-time shaft displacement and vibration amplitude, enabling predictive maintenance and preventing failures like bearing wear or misalignment in turbines, compressors, and motors.

2. What type of connector locking mechanism does this model utilize?

   The probe features a ClickLoc™ connector, which ensures a secure, vibration-resistant connection, eliminating the risk of loosening under high mechanical stress.

3. Is this probe suitable for long-distance installations from the monitoring module?

   Yes. With a total system cable length of 1 meter (plus the probe’s integral cable), it is specifically engineered for installations where the proximitor or monitoring rack is located far from the probe mounting point.

4. How does temperature impact the performance of this probe?

   The probe maintains linearity and accuracy within its operational range of –35°C to +177°C. Performance remains stable due to the high-grade materials used in the sensor’s body and insulation.

5. Can this proximity probe be installed in an oil-contaminated environment?

   Yes. The stainless-steel body and hermetic sealing allow it to operate reliably in environments exposed to oil mist, splashes, or vapors, such as compressor housings and turbine bearings.

6. Does the probe require recalibration during routine maintenance cycles?

   No. The probe is factory calibrated and designed to retain its calibration over years of service unless physically damaged or tampered with.

7. What mounting configurations are supported for the probe’s threaded body?

   It supports 1/4-28 UNF-2A thread for standard mounting brackets and blocks. It can be installed directly or via adjustable probe holders depending on access requirements.

8. What system bandwidth does this probe support for dynamic measurements?

   The probe system is capable of responding to signals up to 10 kHz, making it well-suited for both slow and high-speed rotating equipment where detailed vibration signatures are needed.

9. How does this probe integrate into an existing 3300 XL or 3500 Series monitoring rack?

   It connects via the extension cable to a 3300 XL Proximitor® Sensor, which in turn links to the monitoring rack using standard wiring. No additional signal conditioning is required.

10. Is it possible to use this probe in an environment requiring API 670 compliance?

    Yes. The entire 3300 XL proximity system, including this probe model, is engineered and tested to meet API 670 specifications for vibration and position monitoring in critical machinery.
