Key Features and Benefits
The BENTLY 60M100-00 leverages advanced eddy current technology to deliver non-contact measurement of shaft displacement and vibration, eliminating the risk of mechanical wear from physical contact with moving parts. This ensures long-term reliability and reduces maintenance needs compared to contact-based sensors.
Its high measurement accuracy—within ±0.1% of full scale—enables precise detection of subtle shaft movements, such as those caused by bearing degradation or misalignment, which are early indicators of potential failure. This level of precision is critical for avoiding unplanned downtime in high-value machinery.
Constructed from 316 stainless steel, the BENTLY 60M100-00 withstands corrosive environments, high temperatures, and heavy vibration—common in power plants and oil refineries. The integrated 5-meter cable is shielded to minimize electromagnetic interference, ensuring stable signal transmission even in electrically noisy settings.
Compatibility with Bently Nevada’s 3500 and 3300 series monitoring systems simplifies integration into existing setups, allowing users to leverage their current infrastructure while enhancing data quality. This plug-and-play functionality reduces installation time and training requirements for maintenance teams.
Application Scenarios
The BENTLY 60M100-00 is widely used in industries where rotating machinery reliability is paramount. In coal-fired power plants, it monitors shaft displacement in steam turbines, providing data on rotor position to prevent rubs between rotating and stationary components—failures that can cause catastrophic turbine damage and extended outages.
In oil and gas refineries, the BENTLY 60M100-00 is installed on centrifugal compressors to track vibration and axial thrust, helping operators detect impeller imbalance or seal wear before they lead to unplanned shutdowns. Its corrosion resistance makes it suitable for offshore platforms, where saltwater exposure and humidity would degrade less robust sensors.
Within chemical processing facilities, the sensor monitors agitator shafts in mixing vessels, ensuring proper alignment and detecting bearing wear that could contaminate batches or cause equipment failure. In pulp and paper mills, it tracks roller vibrations in papermaking machines, preventing sheet breaks and maintaining production quality.

Installation and Maintenance
Installing the BENTLY 60M100-00 requires careful alignment with the target shaft, ensuring the probe tip is perpendicular to the shaft surface and positioned within the recommended 0-25 mm measurement range. The sensor’s threaded body allows secure mounting to machinery housings, with a locknut to prevent loosening from vibration. Cable routing should avoid sharp bends or contact with high-voltage lines to maintain signal integrity, and proper grounding of the shielded cable is critical to reduce interference.
For maintenance, the
BENTLY 60M100-00 requires periodic inspection of the probe tip for oil, dirt, or physical damage, as contaminants can affect measurement accuracy. Cleaning with a soft, lint-free cloth is recommended. Annual calibration using Bently Nevada’s calibration tools ensures continued precision. The cable should be checked quarterly for cuts or abrasions, and replaced if damaged to prevent signal loss. With proper care, the sensor typically delivers reliable performance for 5-7 years in industrial environments.
