Description

Technical Overview

The Bently Nevada 21504-00-32-10-02 is a high-precision, non-contact eddy-current vibration probe engineered for continuous, real-time monitoring of shaft vibration and axial position in critical rotating machinery. Designed for integration into the industry-standard 3300 XL 8 mm sensor system, this probe delivers exceptional linearity, thermal stability, and long-term repeatability—essential for predictive maintenance and asset health management in power generation, oil & gas, petrochemical, and heavy industrial applications. Its robust stainless steel housing and optimized coil geometry ensure reliable performance under extreme environmental conditions, including high temperatures, electromagnetic interference, and mechanical shock.

Calibrated to meet API 670 (4th Edition) standards for machinery protection systems, the 21504-00-32-10-02 provides accurate displacement measurements with a standard linear range of ±2.0 mm (±0.079 in) and a sensitivity of 4.0 V/mm (100 mV/mil). The probe’s integrated cable assembly features low-noise, shielded coaxial construction to minimize signal degradation over extended distances—supporting installations up to 10 meters without compromising signal integrity. When paired with compatible Bently Nevada monitors (e.g., 3500 series), it enables seamless diagnostics, alarm triggering, and trending via Asset Management Software (AMS).

Key Features

• API 670–Compliant Performance: Meets stringent requirements for machinery protection systems, ensuring reliability in safety-critical applications.
• High Thermal Stability: Maintains calibration accuracy across operating temperatures from –30°C to +120°C, minimizing drift in demanding environments.
• Robust Mechanical Design: Hermetically sealed stainless steel body with integral 5-meter low-noise cable and Teflon-insulated connector for corrosion resistance and EMI immunity.
• Plug-and-Play Compatibility: Directly interfaces with Bently Nevada 3300 XL 8 mm proximitor modules and 3500/40M monitors—no field recalibration required.
• Long-Term Reliability: Proven mean time between failures (MTBF) exceeding 100,000 hours, reducing unplanned downtime and lifecycle costs.
