Product Overview
Downtime in oil, gas, and industrial automation often starts with a failed sensor. The Bently Nevada 146054-08-50-00-00 is a 3300 ceramic capped proximity probe built to keep vibration and position monitoring online. This 5-meter probe with a 3/8-24 UNF thread and no connector suits 3300 5 mm systems using a 5 m Proximitor Sensor. With fast dispatch, worldwide, Oil AutoTech helps you avoid long lead times and costly production pauses.

Technical Specifications
Key Parameters That Drive Value
- Linear range: 1.52 mm (60 mils), from 0.25 to 1.78 mm (10 to 70 mils), roughly –4 to –16 Vdc.
- Incremental Scale Factor: 7.87 V/mm (200 mV/mil) ±6.5% over the linear range from 0°C to +45°C.
- Probe tip: Alumina ceramic (Al2O3) for wear resistance.
- Case material: AISI 304 stainless steel.
- Cable: 75 Ω coaxial, FEP insulated, 5.0 m total length.
- Temperature range: –51°C to +177°C operating and storage.
- Pressure: Rated to seal 34 Bar (500 psi) nitrogen.
- DC resistance: 8.73 ± 0.70 ohms from center to outer conductor.
Each spec translates into cost control. The ceramic tip resists abrasion, extending replacement intervals. The wide temperature range reduces the need for extra cooling or heating. The 5 m length matches the required Proximitor Sensor, avoiding adapter costs. The 34 Bar pressure seal suits high-pressure casings without frequent maintenance.
Industry Applications
Where This Probe Pays Off
In oil and gas compressor trains, the 146054-08-50-00-00 monitors shaft vibration. Its ceramic cap handles dirty, high-vibration environments, cutting false trips and unplanned shutdowns. In steam turbine retrofits, the 5 m length reaches junction boxes without extension cables, saving installation labor. For pipeline pump stations, the stainless steel case and FEP cable resist moisture and chemicals, reducing premature failures. Each avoided downtime hour protects revenue.

Maintenance & Reliability
Practical Care for Long Service
Inspect the probe tip periodically for wear or deposits. Check cable insulation for cracks, especially near connectors. Verify mounting torque to prevent loosening from vibration. Keep the target area clean and free of metal debris. Because the probe operates from –51°C to +177°C, ensure ambient conditions stay within this band. These steps lower total cost of ownership and support predictable maintenance budgets.
FAQs
Does this probe include a connector?
No. Option C is 00, meaning no connector. You supply the connector or cable type for your system.
What Proximitor Sensor should I use?
Use a 5 m Proximitor Sensor. The 5 m probe length is designed for that sensor only.
Is the probe pressure-sealed?
Yes. It is rated to seal 34 Bar (500 psi) nitrogen. Higher-pressure modifications are available; contact our custom design department.
What is the operating temperature range?
–51°C to +177°C (–60°F to +351°F) for both operating and storage.
Can I use this probe with a different target material?
The stated accuracy applies to an AISI 4140 steel target. Other targets require separate calibration.
