Bently Nevada 330851-04-000-015-10-00-05 3300 XL 25 mm Proximity Probe

製品紹介

The Bently Nevada 330851-04-000-015-10-00-05 3300 XL 25 mm Proximity Probe is a high-precision, non-contact eddy current sensor designed for the continuous measurement / vibration and displacement in large-scale rotating machinery. As part / the Bently Nevada 3300 XL Series, this probe is engineered for heavy-duty industrial applications that demand exceptional accuracy, long-term stability, and superior environmental resistance.

The 25 mm probe is specifically optimized for large shaft diameters, thick-walled bearing housings, and extended measurement ranges, making it ideal for turbines, compressors, and other large rotating equipment. It works in conjunction with the 3300 XL Proximitor Sensor and extension cable to form a complete proximity measurement system, delivering a highly linear voltage output proportional to the distance between the probe tip and the target surface.

This model (330851-04-000-015-10-00-05) features a 1.0-meter cable length and a robust stainless-steel construction that ensures durability and reliability even in harsh environments with oil, dust, and high vibration levels. It represents Bently Nevada’s continued commitment to providing world-class machinery protection and condition monitoring solutions trusted by industries worldwide.

FAQ

1. What measurement principle does the 330851-04-000-015-10-00-05 probe use?
   It uses the eddy current principle, detecting the change in magnetic field strength caused by the target’s proximity.

2. Can this 25 mm probe be connected to any Bently Nevada Proximitor Sensor?
   It must be connected to a properly matched 3300 XL Proximitor Sensor to maintain factory calibration and ensure accurate output.

3. What is the nominal sensitivity / this probe?
   The sensitivity is approximately 100 mV/mil (4.0 V/mm), allowing precise conversion between displacement and output voltage.

4. How does the 25 mm probe differ from the 8 mm version?
   The 25 mm probe /fers a larger sensing area and longer linear range, suitable for large shaft machinery, whereas the 8 mm probe is designed for smaller equipment.

5. Is the probe compatible with both 3300 and 3500 monitoring systems?
   Yes, it is fully compatible with both Bently Nevada 3300 and 3500 series monitoring and protection systems.

6. Can the probe operate under high vibration conditions?
   Yes, it withstands vibration up to 20 g (peak) and shock levels up to 500 g, suitable for high-speed rotating machinery.

7. How is electromagnetic interference prevented in this probe?
   The internal coaxial cable shielding and grounding system reduce susceptibility to EMI, ensuring signal clarity.

8. What calibration material is the probe designed for?
   It is factory-calibrated for AISI 4140 steel, which is a standard shaft material in industrial applications.

9. Does the probe require additional signal conditioning?
   No, signal conditioning is handled by the associated Proximitor Sensor, which provides the final output to the monitoring system.

10. What effect does temperature have on measurement accuracy?
    The probe is designed to maintain consistent sensitivity within ±5% across its full operating temperature range.
