BENTLY 125768-01
Product introduction
The 125768-01 from Bently Nevada is a specialized signal conditioner, engineered to process and convert signals from vibration sensors and accelerometers into standardized outputs for industrial monitoring systems. As a key component in Bently Nevada’s vibration monitoring ecosystem, the 125768-01 bridges the gap between raw vibration data and control systems, enabling precise measurement of machinery vibration in critical applications.
Designed to work seamlessly with Bently Nevada’s 3300 series velocity sensors—such as the 330106-05-30-10-02-CN—and accelerometers, the 125768-01 transforms dynamic vibration signals into industry-standard 4-20mA or 0-10V outputs. Its compact design and robust performance make it ideal for integrating vibration monitoring into PLCs, DCS, and asset management systems. Whether deployed in power generation, manufacturing, or oil and gas facilities, the 125768-01 plays a vital role in detecting early signs of machinery degradation, such as bearing wear and rotor imbalance.
Core advantages and technical highlights
Vibration-specific signal processing: The 125768-01 features specialized circuitry optimized for vibration measurement, with a frequency response (1Hz to 10kHz) that captures both low-frequency structural vibrations and high-frequency bearing defects. Its advanced filtering capabilities remove electrical noise and extraneous signals, ensuring that only relevant vibration data is transmitted to monitoring systems. This targeted processing enhances the accuracy of vibration analysis, enabling more reliable detection of machinery issues.
Flexible range configuration: Unlike fixed-range conditioners, the 125768-01 offers configurable measurement ranges up to 50mm/s peak velocity, allowing customization to specific machinery requirements. This flexibility makes it suitable for diverse applications, from monitoring low-vibration motors to high-amplitude pump vibrations. The easy-to-adjust range settings simplify system setup and allow for future modifications as monitoring needs evolve.
Space-efficient integration: With its compact DIN rail mount design (90mm x 60mm x 25mm), the 125768-01 fits easily into crowded control cabinets, optimizing space utilization in industrial environments. Its standardized mounting and wiring scheme ensure compatibility with existing control system architectures, reducing installation complexity. The module’s low power consumption (less than 1W) also minimizes heat generation, allowing dense packing with other control components.
Typical application scenarios
In thermal power plants, the 125768-01 is used to condition vibration signals from accelerometers mounted on boiler feed pumps and induced draft fans. By converting raw vibration data into 4-20mA signals, it enables the plant’s DCS to continuously monitor bearing health and detect early signs of impeller imbalance. The conditioner’s ability to operate in high-temperature environments ensures reliable performance near steam lines and hot equipment.
Within automotive manufacturing facilities, the 125768-01 processes signals from velocity sensors on production line robots and conveyor motors. Its fast response time captures rapid vibration changes that indicate gearbox wear or drive belt issues, triggering alerts before mechanical failures disrupt assembly operations. The module’s compact size allows installation in space-constrained robot control cabinets, maintaining clean signal paths in electrically dense environments.
In water treatment plants, the 125768-01 conditions vibration signals from large pumps and mixers, converting them into standardized outputs for SCADA systems. Its robust construction withstands the humid conditions typical in water treatment facilities, while its noise-filtering capabilities ensure accurate measurements despite electrical interference from variable frequency drives. By providing reliable vibration data, the 125768-01 helps prevent unplanned downtime of critical water processing equipment.

Installation, commissioning and maintenance instructions
Installation preparation: Before installing the 125768-01, ensure the DIN rail is securely mounted in a clean, dry enclosure with adequate ventilation. Verify that the 24V DC power supply is properly regulated and grounded to prevent voltage fluctuations. Use shielded twisted-pair cables to connect vibration sensors to the conditioner, with the shield grounded at both ends to minimize electromagnetic interference. Maintain a minimum of 30mm clearance around the module for cooling, and avoid mounting near high-voltage components or heat sources.
Maintenance suggestions: Inspect the 125768-01 quarterly for loose connections, corrosion, or signs of overheating. Clean dust accumulation using compressed air to maintain thermal performance. Calibrate the conditioner annually using a vibration calibrator and precision meter to verify accuracy across the operating range. When troubleshooting signal issues, first check sensor connections, cable integrity, and power supply stability before suspecting module failure. Store spare units in a dry environment at room temperature to preserve component integrity.
