Frequently Asked Questions (FAQ)
General & Application
- What machines is this transducer best for?
It is ideal for large, critical rotating equipment like turbines and compressors in power and oil & gas. - Can I use this with a non-Bently Nevada monitor?
Yes, if the monitor accepts a -1 to -17 Vdc proximity input with proper termination.
Technical & Selection
- How do I choose the correct probe length?
The ‘175’ in the part number means 175mm. Choose based on your mounting bracket depth to the target. - Why is my output voltage not linear?
Check the power supply is below -23.5 Vdc. Verify the target is within the 0.25mm to 2.3mm linear range. - What makes this sensor reliable in harsh plants?
The stainless steel construction, wide temperature range, and high-impact housing ensure long-term durability.

We purchased this 8mm proximity probe for a vibration monitoring upgrade on a large industrial motor. The probe was brand new and passed incoming inspection without issue. Installation was simple, and the probe delivered highly consistent readings once commissioned. It’s currently running in a steel manufacturing environment with high temperatures and vibration levels. OilTech Controls provided professional service and quick turnaround, which helped us meet a tight maintenance schedule. This probe performs exactly as expected and matches OEM quality standards.
