Bently Nevada 146055-90-02-05 3300 Ceramic Capped Reverse Mount Probe

Product Introduction

When rotating machinery experiences unexpected vibration, the 146055-90-02-05 provides reliable measurement data to protect critical assets. This Bently Nevada 3300 Ceramic Capped Reverse Mount Probe is designed for precision gap and vibration monitoring in harsh industrial environments. With a 9.0-meter (29.5 feet) cable and 3/8-24 UNF threads, it integrates seamlessly into existing monitoring systems. The probe features an alumina ceramic tip for durability and AISI 304 stainless steel case for corrosion resistance. This model is part of the trusted 3300 series, known for accuracy in turbine, compressor, and pump applications.

Technical Specifications Breakdown

The 146055-90-02-05 offers a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. The incremental scale factor (ISF) is 7.87 V/mm (200 mV/mil) ±6.5% over the full linear range from 0°C to +45°C. The probe case thread is 3/8-24 with a maximum thread engagement of 0.563 inches. The nominal DC resistance from center conductor to outer conductor is 9.87 ± 0.90 ohms for the 9-meter probe. It operates and stores from -51°C to +177°C (-60°F to +351°F) and is rated to seal 34 Bar (500 psi) nitrogen. The connector option is a miniature ClickLoc coaxial connector with standard cable, and the agency approval option is multiple approvals.

Industry Applications

This probe excels in monitoring radial vibration and thrust position of steam turbines, centrifugal compressors, and large pumps. In oil and gas facilities, the 146055-90-02-05 provides early warning of shaft misalignment or bearing wear, helping prevent unplanned downtime. Power generation plants use it for continuous monitoring of critical rotating equipment, ensuring safe operation under varying loads. The high-temperature rating and pressure seal capability make it suitable for environments where other sensors fail.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF threads into a properly tapped hole. Ensure the target surface is clean and made of AISI 4140 steel for optimal performance. The linear range begins at 0.25 mm (10 mils) from the target; adjust the gap accordingly. Use the miniature ClickLoc coaxial connector for secure cable attachment. Avoid bending the cable beyond its rated radius to prevent damage. Calibrate the system using the specified 10 kΩ load and -24 Vdc power supply for accurate readings.

Maintenance & Reliability

Inspect the probe tip and cable periodically for signs of wear or contamination. The alumina ceramic tip resists abrasion, but verify the gap setting during routine maintenance. Store the probe within its rated temperature range to preserve performance. The stainless steel case withstands corrosive environments, but avoid exposure to extreme chemicals not specified. Regular calibration checks ensure the 146055-90-02-05 maintains its accuracy over time, reducing total cost of ownership.

Selection Guide & Purchasing Advice

Before ordering, verify the total length option (-90 = 9.0 meters) and connector type (02 = miniature ClickLoc coaxial) match your system requirements. The agency approval option -05 provides multiple approvals for global use.
