Frequently Asked Questions

Installation & Setup

• What is the best way to set the probe gap?
• We recommend a 1.27 mm (50 mil) gap. Use a feeler gauge between the probe tip and the target shaft. This position centers the linear range.
• Can I use this sensor with a non-Bently monitor?
• The sensor outputs a -1 to -17 VDC signal. It may work with compatible systems. However, for guaranteed performance, use it with a 3300 XL series monitor.

Product Selection & Experience

• How do I choose the right probe length?
• The “165” in the model number means 165 mm probe length. Choose based on your mounting hole depth. Ensure the tip can reach the required measurement position.
• The reading drifts at high ambient temperature. What could be wrong?
• Check the probe temperature is within the +177°C limit. Ensure the target shaft is not hotter than rated. Verify cable connections are clean and tight. Thermal growth can affect the gap.
• Is this sensor suitable for pump vibration monitoring?
• Yes, it is a classic application. This transducer is ideal for centrifugal pumps, fans, and compressors. It monitors radial vibration to detect bearing wear or impeller issues.

Buying Guide Tips

• Confirm your monitor is a Bently Nevada 3300 XL system.
• Check the required probe length for your machinery mounting.
• Verify the need for hazardous area certifications (like BASEEFA).
• Ensure you have the correct fitting and thread type for your junction box.
• For very long cable runs (over 300m), consult the frequency response chart.
