The BENTLY 330876-03-50-00-00 is a high-precision proximity probe, a foundational component of Bently Nevada’s machinery monitoring solutions, designed to measure shaft vibration, position, and speed in critical rotating equipment. Leveraging eddy current technology, this probe detects minute changes in the gap between its tip and a rotating shaft, converting these changes into electrical signals that feed into machinery protection systems for real-time analysis.
As a key sensor in industrial health monitoring, the BENTLY 330876-03-50-00-00 plays a vital role in early fault detection, tracking anomalies like shaft misalignment, imbalance, or bearing wear that could lead to equipment failure. Its integration with Bently’s 3500 or 3300 monitoring systems ensures seamless data flow for alarms and diagnostics. What distinguishes the BENTLY 330876-03-50-00-00 is its exceptional measurement stability, rugged construction, and compatibility with diverse rotating machinery, making it indispensable for industries where equipment reliability drives operational safety and efficiency—including power generation, oil and gas, and chemical processing.
The BENTLY 330876-03-50-00-00 delivers exceptional performance through its advanced eddy current technology, which ensures precise, non-contact measurement of shaft behavior—critical for avoiding mechanical interference with rotating components. Its 5 mm tip diameter balances sensitivity and measurement range, making it suitable for monitoring both small and medium-sized shafts in turbines, compressors, and motors.
A standout feature is its wide operating temperature range (-54°C to +177°C), enabling reliable operation in extreme environments, from cryogenic applications to high-temperature industrial boilers. The Inconel® housing provides superior corrosion resistance, extending probe lifespan in harsh, chemically aggressive settings like offshore oil platforms or chemical plants.
The 3-meter cable offers flexible installation, allowing placement in tight machinery enclosures while maintaining signal integrity. Its frequency response (0–10 kHz) captures both low-speed positional changes and high-frequency vibration harmonics, ensuring comprehensive machinery health data. Compatible with Bently’s 3500 and 3300 systems, the BENTLY 330876-03-50-00-00 integrates seamlessly into existing monitoring setups, reducing setup time and ensuring data consistency across platforms.
The BENTLY 330876-03-50-00-00 is engineered for critical rotating machinery across industries where precision monitoring is vital. In thermal power plants, it monitors steam turbine shaft vibration and axial position, detecting early signs of rotor imbalance or bearing degradation that could compromise power generation efficiency or safety. Its high-temperature tolerance makes it ideal for installation near turbine casings, where ambient temperatures are elevated.
In oil and gas refineries, the probe tracks centrifugal compressor shaft movement, identifying misalignment or seal wear that could lead to gas leaks or unplanned shutdowns. Its corrosion-resistant housing ensures durability in humid or chemically exposed environments, such as offshore platforms.
Manufacturing facilities use the BENTLY 330876-03-50-00-00 to monitor motor and gearbox shafts, ensuring production line machinery operates within safe vibration limits. By providing real-time data to Bently’s monitoring systems, it enables predictive maintenance, reducing downtime and extending equipment lifespan across all these applications.

Installing the BENTLY 330876-03-50-00-00 requires precise positioning: mount the probe with its tip 0.5–2 mm from the target shaft surface, ensuring alignment perpendicular to the shaft to avoid measurement errors. Secure the cable to prevent vibration-induced damage, using cable clips to route it away from high-temperature or moving parts. Calibrate the probe with a Bently-approved gap voltage tool to ensure the output signal (–2 V to –10 V DC) accurately reflects shaft position.
For maintenance, inspect the probe tip quarterly for wear or debris, which can distort measurements. Check cable integrity for cuts or insulation damage, especially in high-vibration areas. Recalibrate annually using Bently’s calibration standards to maintain accuracy. Replace the
BENTLY 330876-03-50-00-00 if output signals become unstable or the housing shows signs of corrosion, ensuring uninterrupted machinery monitoring.
