BENTLY 330101-00-08-20-12-05 3300 XL Proximity Probe
Product Overview
The BENTLY 330101-00-08-20-12-05 is a high-precision 3300 XL Proximity Probe designed for continuous monitoring of shaft displacement and vibration in critical rotating machinery. As a core component of Bently Nevada’s 3300 Series Machinery Protection System, this probe converts mechanical movements into electrical signals, enabling real-time analysis of shaft position, vibration amplitude, and dynamic behavior in turbines, compressors, and generators. The 330101-00-08-20-12-05 integrates seamlessly with 3300 Series monitors (e.g., 3300/42M) and 3500 Series rack systems, delivering reliable measurements to support predictive maintenance across industries such as oil & gas, power generation, and manufacturing.
Featuring a rugged stainless-steel construction, the BENTLY 330101-00-08-20-12-05 includes an 8 mm diameter probe tip, 20 ft (6.1 m) extension cable, and integral temperature compensation for consistent performance. The probe provides a measurement range of 0–250 mils (0–6.35 mm) with ±0.5% linearity, ensuring precise detection of shaft movements. Its hermetically sealed enclosure (IP65-rated) and corrosion-resistant materials protect against dust, moisture, and chemical exposure, while the wide temperature range (-40°C to +177°C) makes it suitable for high-temperature applications. The probe supports standard 2-wire installations, simplifying integration with existing monitoring networks.
In automation ecosystems, the 330101-00-08-20-12-05 serves as a front-end sensor for machinery protection systems, feeding real-time displacement data to monitoring modules for trend analysis and alarm activation. Its compatibility with industry standards (e.g., API 670) ensures safety compliance, while low-output impedance minimizes electromagnetic interference. By providing actionable insights into shaft health, this probe helps reduce unplanned downtime and extend equipment lifespan.

Key Features and Advantages
High-Accuracy Displacement Measurement: The 330101-00-08-20-12-05 provides precise shaft displacement readings with ±0.5% linearity, enabling early detection of misalignment or bearing wear. Its wide measurement range accommodates both minor and significant machinery movements, supporting comprehensive health analysis.
Rugged Industrial Design: The probe’s stainless-steel housing and IP65 rating protect against harsh conditions, including water jets, dust, and corrosive gases. The high-temperature tolerance (up to +177°C) allows direct mounting on hot surfaces like turbine casings without additional cooling.
Seamless System Integration: Compatible with BENTLY’s 3300 and 3500 Series monitoring systems, the probe simplifies integration with existing infrastructure. The standard cable length (20 ft) and industry-standard interface reduce installation complexity and costs.
Reliable Signal Integrity: Built-in temperature compensation and shielded cabling minimize environmental interference, ensuring consistent signal quality. The probe’s non-contact sensing principle eliminates wear, enhancing long-term reliability.
Application Flexibility: Suitable for radial vibration and axial displacement monitoring, the 330101-00-08-20-12-05 supports diverse machinery types. Its modular design allows flexible installation in tight spaces or remote locations.
Application Areas
The BENTLY 330101-00-08-20-12-05 is essential for machinery health monitoring in critical industries:
- Oil & Gas: Monitors shaft displacement in compressors, pumps, and turbines at refineries and offshore platforms to detect misalignment or bearing degradation.
- Power Generation: Installed on steam turbines and generators to ensure safe operation and grid stability by tracking shaft vibrations and position.
- Manufacturing: Used in high-speed rotating machinery (e.g., motors, fans) in automotive and chemical plants to maintain production continuity.
- Aerospace & Defense: Deployed on test stands and propulsion systems to analyze shaft dynamics for performance validation.
Specific applications include:
- Radial Vibration Analysis: Measures shaft vibration to identify imbalance or misalignment issues before they escalate.
- Axial Displacement Monitoring: Tracks thrust bearing wear in turbines, triggering alarms when clearances exceed safe limits.
- Shaft Position Sensing: Monitors rotor position in critical processes to prevent metal-to-metal contact.

Installation and Maintenance
Pre-installation Preparations:
Before installing the 330101-00-08-20-12-05, verify the mounting surface is flat and free of debris. Use a torque wrench to secure the probe (recommended torque: 11–14 N·m) and route the extension cable away from high-voltage lines. Connect the probe to a compatible monitor (e.g., 3300/42M) and ensure proper grounding to reduce noise. Calibrate the system with a known displacement source to validate accuracy.
