Description

Technical Overview

The Bently Nevada 330881-28-00-214-00-02 PROXPAC XL Proximity Transducer is a high-precision, ruggedized industrial sensor engineered for continuous, non-contact monitoring of shaft vibration, axial position, and differential expansion in critical rotating machinery. Designed for demanding environments—including power generation turbines, compressors, pumps, and large motors—the PROXPAC XL delivers exceptional signal stability, low noise floor, and superior temperature compensation across extended operating ranges (–40°C to +125°C ambient). Its integrated electronics eliminate the need for external前置 amplifiers, reducing system complexity, wiring points, and potential failure modes while maintaining full compatibility with legacy Bently Nevada 3300 and System 1 monitoring platforms.

This transducer utilizes advanced eddy-current technology with a stainless-steel probe housing and optimized coil geometry to ensure repeatable sensitivity (typically 7.87 V/mm or 200 mV/mil) and linearity within ±1% over its specified linear range. The 330881-28-00-214-00-02 variant features a 28 mm probe diameter, 14 mm linear range, and integral 5-meter armored cable with high-temperature PTFE insulation—making it ideal for high-vibration, high-EMI, and washdown-prone applications. Its robust mechanical design meets IP67 ingress protection and exceeds IEC 60068-2 environmental stress standards, ensuring long-term reliability in harsh industrial settings where sensor uptime directly impacts operational availability and predictive maintenance integrity.

Key Features

• Integrated Signal Conditioning: Built-in amplifier and demodulator eliminate external前置 electronics—reducing installation time, calibration points, and system footprint.
• Extended Temperature Stability: Compensated performance from –40°C to +125°C ensures accuracy in extreme thermal cycling environments (e.g., turbine casings, refinery compressors).
• Ruggedized Construction: Stainless-steel probe body, PTFE-insulated armored cable, and IP67-rated connector housing resist corrosion, abrasion, and mechanical shock.
• Industry-Standard Compatibility: Fully interoperable with Bently Nevada 3300/3500 monitoring systems and System 1 software—enabling seamless integration into existing asset health programs.
• High Immunity to EMI/RFI: Shielded design and differential output architecture maintain signal fidelity in electrically noisy plants (e.g., near VFDs, switchgear, or arc furnaces).
