Product Overview: BENTLY 125768-01
The BENTLY 125768-01 Proximitor™ Module is a high-precision industrial sensor interface designed for real-time monitoring of shaft vibration and displacement in rotating machinery. As a critical component of Bently Nevada’s 3500 Series Machinery Health Monitoring System, this module converts eddy current probe signals into standardized electrical outputs, enabling precise measurement of mechanical parameters such as shaft position, vibration amplitude, and keyphasor timing. Engineered for reliability in harsh industrial environments, the 125768-01 combines advanced signal conditioning technology with a rugged design to deliver consistent performance in mission-critical applications.
Featuring a dual-channel configuration, the 125768-01 supports two proximity probes simultaneously, enhancing system redundancy and coverage for complex machinery setups. Its 24V DC power input and standardized 4–20 mA output ensure compatibility with most industrial control systems, while the built-in self-diagnostic functions monitor probe health and signal integrity in real time. The module’s compact design (160 mm x 110 mm x 250 mm) and DIN rail mounting facilitate integration into control cabinets, while its -40°C to +85°C operating temperature range ensures resilience in extreme industrial conditions.
Within automation ecosystems, the 125768-01 serves as a foundational element for predictive maintenance strategies, providing critical data to identify early signs of machinery degradation. Its compatibility with Bently Nevada’s 3500 Rack System (e.g., 3500/05) and System 1 software enables seamless integration with distributed control systems (DCS) and supervisory control and data acquisition (SCADA) platforms, making it essential for industries reliant on uninterrupted machinery operation.
