Frequently Asked Questions (FAQ)
Q1: What is the total length of this probe?
The Bently Nevada 330706-005-046-50-00-00 has 5.0 meters (16.4 feet) total length. However, this probe works only with the five meter Proximitor Sensor. Always match probe length to your Proximitor Sensor length.
Q2: What is the weight of this reverse mount probe?
This probe weighs only 0.07 kg. The light weight makes installation easy. Reverse mount design also saves space in tight areas.
Q3: Does this probe need pressure testing before use?
Probes are not pressure tested before shipment. The Viton O-ring provides the pressure seal. Contact our custom design department if you need a pressure seal test for your specific application.
Q4: What torque should I use for installation?
Recommended torque is 7.5 N•m (66 in•lb). Maximum torque is 22.6 N•m (200 in•lb). Use a torque wrench for accuracy. Over-tightening can damage the probe case or threads.
Q5: What is the temperature range for this probe?
Operating range is -52°C to +177°C (-62°F to +351°F). Do not expose the probe below -34°C for long periods. Low temperature exposure may cause the pressure seal to fail early.
Buying Guide
When you buy a 3300 XL 11 mm Reverse Mount Probe, follow these tips. First, check your Proximitor Sensor length. Five meter probes need five meter Proximitors. Second, confirm your mounting thread type. This model uses M10 x 1 threads. Third, pick the right unthreaded length for your mounting depth. Zero mm works for most standard holes. Fourth, decide if you need a longer cable. This 5.0 meter cable is for standard applications. Fifth, check your agency approval needs. Option 00 has no approvals. For hazardous areas, pick option 05 instead. Sixth, verify your target material. Standard calibration uses AISI 4140 steel. For other materials, request custom calibration. Finally, check the warranty terms. We offer 12 months coverage from shipment date.
