Professional FAQ

• What is a reverse mount probe?
• It mounts from the opposite side. This saves space in tight machinery.
• Why is the torque lower than standard probes?
• Reverse mount design uses smaller M10 threads. Lower torque prevents damage.
• Experience: We saw unstable readings after installation.
• Check the cable bend radius. Keep it above 25.4 mm. Tight bends cause signal noise.
• Experience: The O-ring seal failed in cold weather.
• Do not use below -34°C. The Viton O-ring may crack. Warm the area first.
• Buying guide: Reverse mount or standard probe?
• Pick reverse mount (330706) for tight spaces with M10 holes. Pick standard for larger M14 or M16 holes.
• Buying guide: Do I need multiple approvals (option 05)?
• Yes for hazardous areas. No for general factories. Check your local safety rules.
• Buying guide: What cable length is best?
• 5 meters matches the 5m Proximitor. Do not mix lengths. Use 1m or 9m only if your Proximitor matches.
• Does the probe come pressure tested?
• No. Contact Bently Nevada custom design if you need a pressure seal test.
