Description

Technical Overview

The Bently Nevada 330708-00-20-50-02-00 is a high-precision 3300 XL 11 mm proximity probe engineered for demanding industrial condition monitoring and machinery protection applications. As part of the industry-standard 3300 XL series, this probe delivers exceptional linearity, thermal stability, and electromagnetic interference (EMI) immunity—critical attributes for reliable operation in harsh environments such as power generation, oil & gas, petrochemical, and heavy manufacturing facilities. Its robust stainless steel construction and hermetically sealed design ensure long-term performance under extreme temperatures, vibration, and exposure to moisture or corrosive agents.

Designed specifically for integration with Bently Nevada 3300 XL monitoring systems, the 330708-00-20-50-02-00 provides accurate non-contact measurement of shaft displacement, vibration, and position across rotating machinery—including steam and gas turbines, compressors, motors, and pumps. The probe’s optimized 11 mm diameter sensing face offers an ideal balance between resolution and standoff distance, supporting measurement ranges up to 2.0 mm (80 mils) with ±1% linearity and minimal temperature drift (<0.05%/°C). Its factory-calibrated output ensures seamless compatibility with 3300 XL extension cables and transducers, eliminating field recalibration and reducing commissioning time.

Key Features

• Precision 11 mm Sensing Tip: Optimized for high-resolution shaft vibration and axial position monitoring with consistent sensitivity and minimal phase shift.
• Hermetically Sealed Construction: Stainless steel housing with ceramic insulator and epoxy-sealed cable exit for superior resistance to moisture, oil, and chemical exposure.
• EMI/RFI Immunity: Meets IEC 61000-4-3 and -4-6 standards, ensuring stable operation near VFDs, switchgear, and high-power motor controls.
• Factory-Calibrated & System-Ready: Pre-matched to Bently Nevada 3300 XL transducers and extension cables—no field calibration required.
• Extended Temperature Range: Operational capability from –30°C to +120°C ambient, with short-term tolerance up to +150°C.
