3300 XL 11 mm Probe 330709 Bently Nevada – Premium M16 Proximity

Description

Product Description

The 3300 XL 11 mm Proximity Probes from Bently Nevada monitor shaft vibration and position. Model 330709-016-240-50-02-00 uses a M16 x 1.5 thread without armor. It has a 16 mm unthreaded length and a 240 mm overall case length. Total cable length is 5.0 metres (16.4 feet). This 5 meter probe works only with the 5 meter Proximitor Sensor. The probe includes a miniature coaxial ClickLoc connector with standard cable. Each unit ships new in original factory packing with a 12-month warranty.

Professional FAQ

• Why must this 5m probe pair only with a 5m Proximitor Sensor? The cable length changes resistance and capacitance. Matching lengths ensures correct calibration and linear output. Using wrong length causes measurement errors.
• What does unthreaded length 016 mean for installation? You have 16 mm of smooth case before threads start. This helps position the probe tip deeper inside a housing without threading the whole case.
• Can I use this probe in a vacuum or high pressure environment? The Viton O-ring seals differential pressure. Bently Nevada does not pre-test each probe. Contact their custom team if you need a pressure test certificate.
• The case length is 240mm – very long. Where would I need this? Long reach applications like through thick bearing housings or past oil deflectors. Measure your mounting hole depth before ordering.
• What does approval option 00 mean for my plant? No safety agency certification. Suitable for internal use where local regulations do not require Ex or other approvals. Check your local codes first.

Buying Guide – Selection Tips

• Choose unthreaded length 016 when you need deep tip positioning
• Pick case length 240 for reaching through thick walls or long holders
• Select total length 50 (5m) only if your Proximitor is also 5m version
• Use connector 02 (standard cable) for dry clean environments
• Pick approval 00 when no certificate needed (saves cost)
• Need 1 meter cable? Order total length 10 instead
• Need armor for crush protection? Look at 330704 or 330706 models
• Verify shaft diameter is 152 mm or larger before buying
• Check flat target area: must be at least 30.5 mm wide
• Store probe above -52°C and below +105°C when not in use
