1. Product Overview and Core Functionality
The Bently Nevada 8111 is a high-precision, rack-mounted proximity probe system designed for critical machinery protection and condition monitoring in industrial automation. This system integrates eddy current sensors to measure shaft displacement, vibration, and speed in rotating equipment such as turbines, compressors, and motors. The 8111 features a modular design with a probe, extension cable, and preamplifier, ensuring reliable operation in extreme temperatures (-40°C to 150°C) and high-electrical-noise environments. Its linear output (e.g., 200 mV/mil sensitivity) enables precise detection of mechanical faults like misalignment, bearing wear, or rotor instability. Built for durability, the 8111’s stainless steel probe and IP67-rated components resist corrosion and moisture, making it ideal for oil and gas, power generation, and heavy industrial applications.
2. Technical Specifications and System Integration
The 8111 system operates on a -24 VDC power supply and delivers a frequency response up to 10 kHz, capturing both low-speed and high-frequency dynamic changes. It supports probe diameters of 5 mm to 8 mm, with a linear measurement range of up to 2 mm (80 mils) and resolution as fine as 1 µm. Compliant with API 670 standards for machinery protection, it integrates seamlessly with Bently Nevada’s System 1™ software for real-time diagnostics and predictive maintenance. The system includes anti-rotation mechanisms to prevent cable damage and electromagnetic shielding to reduce interference. Hot-swappable components and front-accessible terminals simplify maintenance, while certifications like ATEX/IECEx ensure safe use in hazardous zones.
3. Applications and Operational Benefits
The 8111 is indispensable in industries requiring precise shaft monitoring, such as petrochemical plants, hydroelectric facilities, and aerospace testing. By tracking shaft position and vibration trends, it prevents catastrophic failures, reducing unplanned downtime and repair costs. Its compatibility with legacy and modern control systems facilitates smooth upgrades, while rugged construction ensures longevity in high-vibration, corrosive environments. The system’s diagnostic capabilities enable early detection of issues like thermal growth or thrust bearing wear, supporting data-driven decisions to optimize machinery lifespan and safety. Trusted globally, the 8111 exemplifies Bently Nevada’s expertise in delivering scalable, reliable solutions for industrial automation challenges.
