BENTLY 125760-01

Product introduction

The 125760-01 from Bently Nevada is a compact, high-precision sensor signal conditioner, specifically engineered to process and amplify signals from proximity probes in machinery monitoring systems. As a key component in Bently Nevada’s sensor ecosystem, the 125760-01 transforms raw eddy current probe signals into standardized analog outputs, enabling seamless integration with PLCs, DCS, and machinery protection systems.

Designed to work with Bently Nevada’s 3300 series proximity probes—such as the 330130-080-00-CN—the 125760-01 provides accurate conversion of shaft displacement measurements into industry-standard 4-20mA or 0-10V signals. Its compact size and rugged construction make the 125760-01 ideal for space-constrained industrial environments, ensuring reliable performance in applications ranging from turbine monitoring to pump health surveillance. By conditioning proximity probe signals, the 125760-01 plays a critical role in early detection of machinery issues like shaft misalignment and bearing wear.

Core advantages and technical highlights

Precision signal conversion: The 125760-01 delivers exceptional measurement accuracy of ±0.25% across its 0-2.5mm range, ensuring reliable conversion of proximity probe signals into actionable data. Its advanced signal processing filters out electrical noise and interference common in industrial environments, preserving the integrity of critical displacement measurements. This precision makes it suitable for applications requiring fine resolution, such as monitoring shaft position in high-speed turbines.

Compact, rugged design: With its DIN rail mountable form factor (90mm x 60mm x 25mm), the 125760-01 fits easily into crowded control cabinets, saving valuable space in industrial installations. Its robust construction withstands extreme temperatures (-40°C to 70°C) and vibration, ensuring reliable operation in harsh environments like refineries and power plants. The module’s solid-state design minimizes moving parts, reducing maintenance requirements and extending service life.

Easy integration: The 125760-01 simplifies system integration with its standardized analog outputs (4-20mA and 0-10V), compatible with virtually any industrial control system. It requires minimal configuration beyond basic range setting, allowing for quick installation and commissioning. The conditioner’s wide input compatibility works with various proximity probe lengths and types, providing flexibility in system design and upgrades.

Typical application scenarios

In hydroelectric power plants, the 125760-01 is used to condition signals from proximity probes monitoring turbine shaft position and vibration. Mounted in control cabinets near generator sets, it converts raw probe data into 4-20mA signals for transmission to the plant’s DCS. This allows operators to continuously monitor shaft displacement, detecting issues like rotor imbalance or bearing degradation before they lead to costly turbine failures. The 125760-01’s ability to operate in damp environments makes it well-suited to the conditions found in hydroelectric facilities.

Within pulp and paper mills, the 125760-01 processes signals from proximity probes on large rollers and dryer cylinders. Its compact design fits easily into control panels near production lines, while its noise-filtering capabilities ensure accurate measurements despite the electrical interference from motors and drives. By providing reliable shaft displacement data, the 125760-01 helps prevent roller misalignment—an issue that can cause paper defects and production losses.

In chemical processing plants, the 125760-01 conditions proximity probe signals from agitators and mixers in hazardous areas (when properly installed in certified enclosures). It converts these signals into standardized outputs for monitoring by the plant’s safety system, enabling early detection of shaft movement that could indicate seal failure or bearing wear. The module’s robust construction ensures reliable operation even in environments with chemical exposure and temperature fluctuations.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the 125760-01, ensure the DIN rail is properly mounted in a clean, dry enclosure with adequate ventilation. Verify the 24V DC power supply is stable and properly grounded to prevent electrical noise. Use shielded twisted-pair cables to connect proximity probes to the 125760-01, grounding the shield at both ends to maximize noise rejection. Leave at least 30mm of space around the module for airflow, and avoid mounting near heat sources or high-voltage components.

Maintenance suggestions: Inspect the 125760-01 quarterly for loose connections or signs of overheating (discoloration or unusual odors). Clean dust from the module using compressed air to maintain thermal efficiency. Calibrate the conditioner annually using a precision signal generator and calibrated meter to verify accuracy across the measurement range. If signal quality degrades, check probe connections and cable integrity before replacing the 125760-01—many issues stem from external factors rather than module failure. When replacing, ensure the new unit is properly configured to match probe specifications.
