Frequently Asked Questions (FAQ)
What is the correct installation torque?
Use 5.1 N·m (45 in-lb) on the probe case. Do not exceed 7.3 N·m.
What power supply is required?
A -24 VDC supply is ideal. The range is -17.5 to -26 VDC.
Does the target material matter?
Yes. Specifications use AISI 4140 steel. Different materials change sensitivity.
What is the operating temperature limit?
The probe works from -35°C to +177°C. Avoid below -34°C to protect seals.
How do I connect the cable?
Connect the ClickLoc connector by hand. Ensure it clicks into place. Never use tools.
The signal has noise. What should I check?
This probe has high magnetic immunity. Verify system grounding and cable routing first.
How do I select the right probe?
Confirm your system uses Bently Nevada 5mm probes. Check required cable length and thread type.
Can I use a longer cable?
This model has a fixed 0.5m cable. Use approved extension cables for longer distances.
Selection Guide
- Verify compatibility with your Bently Nevada monitoring system.
- Select the thread type and material for your mounting point.
