Product Overview
When rotating machinery vibration threatens uptime, the Bently Nevada 146054-08-50-00-00 delivers reliable measurement. This 3300 Ceramic Capped Proximity Probe is designed for critical asset protection in industrial environments. With a 5.0-meter cable and no connector, it integrates seamlessly into existing monitoring systems. The probe features a 3/8-24 UNF thread and alumina ceramic tip for durability.
Technical Specifications
The 146054-08-50-00-00 operates within a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. Its incremental scale factor is 7.87 V/mm (200 mV/mil) ±6.5% over the full linear range. The probe case is AISI 304 stainless steel, and the tip is alumina ceramic (Al2O3). Operating temperature spans -51°C to +177°C (-60°F to +351°F), with pressure rating to 34 Bar (500 psi) nitrogen. Nominal DC resistance from center conductor to outer conductor is 8.73 ± 0.70 ohms.
Industry Applications
This proximity probe excels in turbomachinery monitoring, including steam turbines, compressors, and pumps. Its ceramic cap withstands harsh conditions, making it suitable for oil and gas, power generation, and petrochemical plants. The 5-meter cable length matches standard 5m Proximitor Sensors for straightforward installation.
Installation & Setup Guidance
Mount the probe with the 3/8-24 UNF thread into a suitable mounting block. Ensure the target is AISI 4140 steel for optimal performance. The maximum thread engagement length is 0.563 inches. Connect the coaxial cable to a compatible Proximitor Sensor; for the 5m probe, use only the 5m Proximitor Sensor. Verify the gap within the linear range (0.25 to 1.78 mm) during installation.
Maintenance & Reliability
Inspect the probe cable and connector periodically for wear or damage. The ceramic tip resists abrasion, but verify cleanliness of the target surface. The stainless steel case provides corrosion resistance in most industrial environments. For extended life, avoid exceeding the rated temperature or pressure limits.
Compatibility & Integration
This probe is part of the 3300 XL system and works exclusively with 3300 series Proximitor Sensors and extension cables. The 5-meter probe is designed for use with the 5m Proximitor Sensor only. System accuracy specifications apply when using AISI 4140 steel targets and -24 Vdc power supply with a 10 kΩ load.
Selection Guide & Purchasing Advice
Before ordering, confirm your system requires a 5.0-meter probe without a connector. The 146054-08-50-00-00 is new and original in factory packing with a 12-month warranty from SpareTechPLC. Verify compatibility with your existing Proximitor Sensor and cable type. For higher-pressure applications, contact our custom design department.
