Introduction
Over the past decades, industrial machinery monitoring has evolved from simple manual inspections to sophisticated, real-time condition-based maintenance systems. The Bently Nevada 146054-08-10-00-00 represents a key component in this evolution, offering precise, non-contact displacement measurements essential for protecting critical rotating assets. This 3300 Ceramic Capped Proximity Probe is designed for demanding environments where accuracy and reliability are non-negotiable.
Product Overview
The 146054-08-10-00-00 is a 3300 Ceramic Capped Proximity Probe from Bently Nevada, featuring a 3/8-24 UNF thread and a 0.8-inch overall case length. It comes with a 1.0-meter (3.3 feet) total probe length and a no-connector option (0 0). The probe tip is made of alumina ceramic (Al2O3), and the case is AISI 304 stainless steel. This probe is part of the 3300 5 mm system and is designed to work with a Proximitor Sensor and extension cable for accurate vibration and position monitoring.
Technical Specifications Breakdown
- Linear Range: 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target, corresponding to -4 to -16 Vdc output.
- Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±6.5% including interchangeability error, measured over the 60 mil linear range from 0°C to +45°C (+32°F to +113°F).
- Probe Temperature Range: Operating and storage from -51°C to +177°C (-60°F to +351°F).
- Pressure Rating: Sealed to 34 Bar (500 psi) nitrogen.
- Probe DC Resistance: For a 1.0-meter probe, resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms.
Industry Applications
This probe is ideal for monitoring vibrations and shaft position in turbines, compressors, pumps, and other rotating machinery. Its ceramic tip provides wear resistance and stable performance in high-temperature environments up to +177°C. The 1.0-meter cable length suits installations where the probe is close to the machine, reducing signal loss. The no-connector option simplifies field wiring for permanent installations.
Installation & Setup Guidance
When installing the 146054-08-10-00-00, ensure the probe tip is properly positioned within the linear range (0.25 to 1.78 mm from the target). The maximum thread engagement length is 0.563 inches. Use a 24 Vdc power supply with a 10 kΩ load for optimal performance. Calibrate the system using an AISI 4140 steel target as specified. Avoid exceeding the pressure rating of 34 Bar (500 psi) unless modifications are made for higher pressures.
Maintenance & Reliability
Regularly inspect the probe cable for damage and verify the DC resistance between center and outer conductors (7.59 ± 0.50 ohms for 1.0-meter length). Ensure the probe tip remains clean and free from debris. The ceramic tip and stainless steel case offer excellent corrosion resistance. For safety-rated applications, follow the manufacturer's guidelines for periodic testing and verification.
Compatibility & Integration
The 146054-08-10-00-00 is designed for use with Bently Nevada 3300 series Proximitor Sensors and extension cables. It operates with a -24 Vdc power supply and a 10 kΩ load. The system accuracy and interchangeability specifications apply only when using AISI 4140 steel targets. For other targets, contact Bently Nevada for custom calibration.
Selection Guide & Purchasing Advice
Before ordering, verify the overall case length (0.8 inches), total probe length (1.0 meter), and connector option (0 0 = no connector). Confirm the thread type (3/8-24 UNF) and ensure compatibility with your Proximitor sensor. SpareTechPLC offers this probe in new, original factory packaging with a 12-month warranty. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
