Product Overview

The 330101-00-43-15-02-00 is a high-performance eddy current proximity sensor from the Bently Nevada 3300 XL 8 mm series. Designed for non-contacting displacement measurements, this probe converts the physical gap between the sensor tip and a conductive target—typically a rotating shaft—into a proportional voltage signal. It is an essential component for Turbine Supervisory Instrumentation (TSI), facilitating real-time monitoring of radial vibration, axial thrust, and shaft position in critical industrial machinery such as gas turbines, compressors, and high-speed pumps.

Technical Configuration and Build

The specific configuration of the 330101-00-43-15-02-00 model follows the standard Bently Nevada ordering matrix to define its physical and electrical profile:

• Model Identification: 330101 (3/8-24 UNF Thread, No Armor)

• Unthreaded Body Length: 0.0 inches (Fully threaded case)

• Overall Case Length: 4.3 inches

• Total System Length: 1.5 Meters (4.9 feet)

• Connector Type: Miniature coaxial ClickLoc connector (02 option)

• Agency Approval: Standard (00 option - No specific hazardous area certification)

• Calibration Target: AISI 4140 steel (Standard)

Advanced Engineering and Durability

The 3300 XL series represents a significant advancement in sensor longevity and signal integrity. This probe utilizes the patented TipLoc molding process, which creates a molecular bond between the probe tip and the stainless steel body. This prevents the "wicking" of oil and process fluids into the sensing coil, ensuring vacuum-tight integrity.

The 1.5-meter integrated cable is equipped with the ClickLoc connector system, featuring gold-plated brass components and a mechanical locking mechanism that prevents accidental disconnection in high-vibration zones. Additionally, the sensing coil is encapsulated in high-performance Polyphenylene Sulfide (PPS) plastic for superior chemical resistance and thermal stability.

Functional Applications

As a core element of machinery protection systems, this proximity transducer serves several vital functions:

• Radial Vibration Monitoring: Observing shaft dynamic motion within fluid-film bearings.

• Axial Position Tracking: Measuring the longitudinal displacement of rotors to prevent catastrophic thrust bearing contact.

• Keyphasor Signal Source: Providing timing and speed references for phase angle measurements and RPM tracking.

• Backward Compatibility: Electrically compatible with legacy non-XL 3300 series 5 mm and 8 mm proximity systems.

• Enhanced RFI/EMI Immunity: Engineered to meet European CE standards without requiring specialized shielded conduit.
