Product Overview

When vibration monitoring in critical rotating machinery demands precision and reliability, the Bently Nevada 146054-036-50-02-05 delivers. This 3300 Ceramic Capped Proximity Probe is designed for non-contact displacement measurements in harsh industrial environments. With a 3.6-inch overall case length and 5.0-meter total cable, it integrates seamlessly into turbine, compressor, and pump protection systems. The probe features a 3/8-24 UNF thread and comes without armor, making it suitable for standard mounting configurations. Factory-packed as new with a 12-month warranty, this unit ensures authentic performance.

Technical Specifications Breakdown

The 146054-036-50-02-05 offers key specifications that define its capability. The probe case thread is 3/8-24, with a maximum thread engagement length of 0.563 inches. The total length option is 5.0 meters (16.4 feet), designed exclusively for use with the 5 m Proximitor Sensor. The connector and cable-type option is a miniature coaxial ClickLoc connector with standard cable. Agency approvals include CSA, ATEX, and IECEx, ensuring compliance with global safety standards. The probe tip material is alumina ceramic (Al2O3), and the case material is AISI 304 stainless steel. Operating and storage temperature range is -51°C to +177°C (-60°F to +351°F), and the probe is rated to seal 34 Bar (500 psi) nitrogen.

Industry Applications

This proximity probe excels in applications where reliable shaft vibration and position monitoring are critical. In steam turbines, the 146054-036-50-02-05 provides accurate gap voltage measurements over a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm from the target. For centrifugal compressors in oil and gas facilities, the ceramic cap resists wear and contamination, extending service life. The probe's 5-meter cable length suits installations where the Proximitor sensor is mounted remotely, reducing electrical noise interference. Its ATEX and IECEx certifications allow use in hazardous areas, making it a trusted choice for refinery and chemical plant machinery protection systems.

Installation & Setup Guidance

Proper installation of the 146054-036-50-02-05 ensures accurate readings. Mount the probe using the 3/8-24 UNF thread into a compatible mounting block or bracket. Ensure the thread engagement does not exceed 0.563 inches to avoid mechanical interference. Connect the miniature coaxial ClickLoc connector to the extension cable, then route the standard 75 Ω coaxial cable to the Proximitor sensor. For best performance, calibrate the system with an AISI 4140 steel target at 24 Vdc supply and 10 kΩ load. Verify the gap voltage falls within the -4 to -16 Vdc range over the linear span. Always follow the manufacturer's guidelines for torque and clearance.

Maintenance & Reliability

Routine inspection of the 146054-036-50-02-05 focuses on the probe tip and cable integrity. The alumina ceramic tip resists damage from debris and high temperatures, but check for cracks or contamination during scheduled outages. Verify the cable jacket for cuts or abrasion, especially near connection points. The probe's stainless steel case withstands corrosive atmospheres, but ensure the mounting threads remain clean and lubricated. Given the 5-meter cable length, avoid sharp bends that could degrade signal quality. Regular system calibration checks using a known target help maintain measurement accuracy over the probe's service life.

Selection Guide & Purchasing Advice

Before purchasing the 146054-036-50-02-05, confirm your system requirements. This probe is designed for 5-meter systems and must be paired with the corresponding 5 m Proximitor sensor. Verify the overall case length (3.6 inches) fits your mounting depth. The 3/8-24 UNF thread is standard, but check for thread compatibility with your bracket. For hazardous area installations, the -05 agency approval option covers CSA, ATEX, and IECEx. BluePLC Industrial supplies this probe as new and original in factory packing with a 12-month warranty.
