Bently Nevada 3300 Ceramic Capped Proximity Probe

Product Overview

The 146054-08-05-00-05 is a 3300 series ceramic capped proximity probe from Bently Nevada. This 5 mm system provides non-contact vibration and position measurement. It features a 60 mil (1.52 mm) linear range with a 7.87 V/mm scale factor. The probe uses alumina ceramic tip material and AISI 304 stainless steel case. It is rated for operation from -51°C to +177°C and seals to 34 Bar (500 psi) nitrogen. Agency approvals include CSA, ATEX, and IECEx for hazardous area use.

Oiltech Controls’s Insight

The 146054-08-05-00-05 is a direct replacement for original Bently Nevada 3300 probes. We recommend verifying the total length option (-05 = 0.5m) matches your existing cable run. This probe uses 75 ohm coaxial cable and requires a Bently Nevada Proximitor sensor for operation. The ceramic tip provides excellent wear resistance in high-speed applications. For systems with longer cable runs, consider the 5m or 9m versions (option B). Always use AISI 4140 steel targets for calibration to maintain accuracy. The 3/8-24 thread is standard for most bearing housings.

Frequently Asked Questions

• Can this probe work with a 3300 XL Proximitor?
  Yes, the 146054-08-05-00-05 is fully compatible with all Bently Nevada 3300 XL 5mm Proximitor sensors. System accuracy applies only when using genuine XL components.
• What target material is required for correct calibration?
  For accurate measurements, calibrate the system using an AISI 4140 steel target. Using other materials may cause errors in scale factor and linearity.
• What is the difference between -05 and -09 length options?
  The -05 option provides 0.5 meter total length, suitable for short cable runs. Choose -09 (9 meters) for longer distances between probe and Proximitor. Cable length affects DC resistance and system response.
• How do I verify probe cable continuity?
  Measure DC resistance between center and outer conductors. For 0.5m length, nominal value is 7.45 ± 0.50 ohms. Significant deviation indicates cable damage.
• Is this probe suitable for underwater or high-pressure applications?
  Standard rating is 34 Bar (500 psi) nitrogen. For higher pressures, contact our technical team for custom modification options and seal testing.
