General Information

Core Description

Optimized for heavy-duty industrial rotating machinery, the 330102-00-43-05-02-05 eddy current probe features a reverse-mount design with a 4.3-inch fully threaded 3/8-24 UNF housing. It comes equipped with a 0.5-meter integrated coaxial cable shielded by a rugged stainless steel armor sleeve to withstand severe mechanical abrasion and flying debris. Featuring a premium ClickLoc connector with an integrated connector protector, this 8mm proximity probe ensures seamless signal integrity in oil-mist and high-vibration fluid-film bearing housings. 

Specific Application

• Thrust and Radial Vibration Monitoring: Installed inside internal brackets or brackets within fluid-film bearings on critical steam turbines, centrifugal compressors, and large industrial pumps. 
• Severe Environment Protection: Specially deployed in machinery spaces prone to severe mechanical wear, cutting fluids, or flying metal chips where standard unarmored sensor cables would sustain physical damage. 

Reverse-Mount Access: Used in applications where standard front-mount installation is hindered, allowing external threading into internal machine housings or specialized probe sleeves.

System Compatibility

• Transducer System: The 330102-00-43-05-02-05 proximity probe is fully compatible with the Bently Nevada 3300 XL Proximitor Sensor (e.g., 330180) and 3300 XL Extension Cables (e.g., 330130), forming a standard 5-meter or 9-meter transducer loop.
• API 670 & Backward Compatibility: Designed to be fully interchangeable with legacy, non-XL 3300 series 5mm and 8mm transducer systems, providing seamless backward compatibility compliant with stringent API 670 standards for machinery protection.
• Armored Interface: The stainless steel armor (-02 option) and ClickLoc connector with protector (-05 option) connect smoothly with matching armored or standard 3300 XL extension lines without altering electrical performance or scale factor (200 mV/mil)
• Monitoring Platforms: Fully interfaces with Bently Nevada 3500 Machinery Protection Systems, 3701/55 monitors, and older 3300 rack systems, ensuring plug-and-play field upgrades.
•  

The Bently Nevada 330102-00-43-05-02-05 Proximity Probe serves as a direct, seamless replacement for older legacy models within the industry-standard Bently Nevada 3300 XL 8mm Proximity Transducer System series. This specific high-precision armored probe features a 3/8-24 UNF thread, a 0.0-inch unthreaded length, a 4.3-inch overall case length, and a 0.5-meter total length. It provides backward compatibility, allowing operators to upgrade existing machinery protection infrastructures without physical modifications or recalibration.

Installation & Troubleshooting FAQ

Q1: What is the benefit of the "-02" armor and "-05" option on this probe?

A1: The -02 option adds flexible stainless steel armor that safeguards the fragile coaxial line from sharp bends and physical impact. The -05 option provides a pre-installed connector protector, preventing moisture, turbine oil, and conductive debris from contaminating the ClickLoc terminal. 

Q2: How do I verify if the probe gap is set correctly during installation?

A2: Connect the probe to the Proximitor loop and monitor the DC Voltage output using a digital multimeter. For standard AISI 4140 steel targets, aim for a mid-scale voltage of -10.0 Vdc (which equates to roughly a 1.0 mm or 40 mil physical gap between the probe tip and target surface). 

Q3: What should I do if the monitoring system reports a "NOT OK" fault status?

A3: First, turn off power and check the ClickLoc connection for fluid ingress or physical looseness. Use a multimeter to measure the center-to-outer conductor resistance on the probe cable; a standard 0.5-meter probe should show a nominal DC resistance between 7.0 and 8.0 ohms. A reading of infinity indicates an open circuit, while 0 ohms indicates a shorted cable. 

Q4: Can this 3300 XL probe replace older Bently Nevada 7200 series parts?

A4: While the physical 3/8-24 UNF mounting thread fits older brackets, you cannot mix a 3300 XL probe with a 7200 extension cable or 7200 Proximitor due to different electrical scale factors. The entire transducer loop (probe, cable, sensor) must be upgraded to 3300 XL.
