Description

Technical Overview

The Bently Nevada 21747-045-01 Proximitor Probe Extension Cable is a precision-engineered component designed for seamless integration within critical machinery protection and condition monitoring systems. As part of the industry-standard 3300 XL series ecosystem, this extension cable ensures signal integrity between the proximitor sensor and the monitor—maintaining high-fidelity eddy-current measurements essential for accurate shaft vibration, position, and gap analysis in rotating equipment.

Engineered to meet stringent electromagnetic compatibility (EMC) and environmental requirements, the 21747-045-01 features low-noise coaxial construction with double-shielded, twisted-pair conductors and robust polyurethane jacketing. Its optimized impedance matching (50 Ω nominal) minimizes signal attenuation and phase distortion over extended distances—critical for maintaining calibration accuracy across demanding industrial environments such as power generation, oil & gas, and heavy manufacturing. The cable is rated for continuous operation in temperatures ranging from –40°C to +85°C and exhibits excellent resistance to oil, moisture, and mechanical abrasion.

Key Features

• Signal Integrity Preservation: Precision-matched 50 Ω impedance and dual shielding ensure minimal noise pickup and consistent dynamic response up to 10 kHz.
• Rugged Industrial Construction: Polyurethane outer jacket provides superior cut, crush, and chemical resistance—ideal for harsh plant-floor conditions.
• Plug-and-Play Compatibility: Fully compliant with Bently Nevada 3300 XL Proximitor systems; includes factory-terminated MIL-C-26482 Series II connectors for reliable mating and EMI suppression.
• Calibration Traceability: Manufactured under ISO 9001-certified processes and shipped with individual calibration documentation supporting compliance with API 670 and ISO 10816 standards.
