Product Introduction
The Bently Nevada 330876-03-10-01-00 3300 XL 50 mm Proximity Probe is a high-precision, non-contact sensor designed for monitoring shaft displacement and vibration in critical industrial machinery. Part of the 3300 XL series, this probe delivers accurate, high-fidelity measurements essential for condition monitoring and machinery protection systems. With a 50 mm probe tip, it is optimized for larger machinery applications such as turbines, compressors, and generators. The probe converts mechanical displacement into an electrical signal compatible with Bently Nevada Proximitor® sensors and monitoring systems, providing reliable early detection of misalignment, imbalance, or mechanical degradation.

FAQ
-
What target material provides the most accurate measurement?
AISI 4140 or similar carbon steel is recommended for calibration and best accuracy. -
How is electromagnetic interference minimized?
The probe uses a coaxial design with grounded shielding to reduce external electrical noise. -
Can the probe operate in high-vibration environments?
Yes, it is designed to maintain stable measurements even under severe vibration. -
What is the typical output impedance of the probe system?
Approximately 50 Ω when connected to the specified Proximitor sensor. -
How does the probe compensate for temperature changes?
Internal materials and factory calibration minimize thermal drift across the operating temperature range. -
Is this probe compatible with older Bently Nevada drivers?
It is recommended to use with 3300 XL or 3500 series Proximitor drivers for full performance. -
What is the recommended gap voltage for optimal linearity?
Typically around –10 VDC at mid-gap position. -
How does cable length affect signal quality?
The probe is calibrated for a total system length; any modification requires recalibration. -
What protection does the probe provide against moisture ingress?
The assembly meets IP67 sealing when installed with proper hardware. -
What is the maximum static pressure rating at the probe tip?
The probe tip can withstand pressures up to 2000 psi (137 bar).
