Precise Shaft BN 135137-01 Enhanced Keyphasor Module Industrial Align Clear Mon Turb Rot Equip

The Bently Nevada 135137-01 is a high-performance signal conditioning module designed for industrial machinery health monitoring systems, particularly within the 3500 series platform. It supports dynamic signal processing for vibration, speed, and position sensors, converting raw analog inputs into standardized 4-20 mA or ±10 V outputs. Operating on 24 VDC power with a range of 18-32 VDC, it ensures stable performance in harsh environments (-40°C to +85°C). The module features galvanic isolation (1500 VAC) to eliminate ground loop interference and complies with IEC 61000-6-4 for electromagnetic compatibility (EMC). Its rugged, DIN-rail-mountable design (IP20) integrates seamlessly into control cabinets, while LED diagnostics provide real-time status alerts for fault detection.

This module is critical for predictive maintenance in turbines, compressors, and pumps across oil and gas, power generation, and chemical industries. It processes signals from proximity probes, accelerometers, and tachometers to detect imbalances, misalignment, and bearing wear. The 135137-01 supports dual-channel redundancy, ensuring uninterrupted operation in safety-critical systems. Compatibility with Bently Nevada's System 1® software enables advanced analytics, such as FFT spectrum analysis and automated alarm triggering. Its configurable filter settings (e.g., high-pass, low-pass) allow customization for specific machinery frequencies. Users benefit from reduced downtime due to hot-swappable replacement and compliance with API 670 and ISO 10816 vibration standards.

Certified to global standards (CE, ATEX/IECEx for hazardous zones), the 135137-01 meets SIL 2/3 functional safety requirements for critical infrastructure. It integrates with PROFIBUS, Modbus, and OPC-UA protocols for seamless connectivity to PLCs, DCS, and IoT platforms. The module's firmware supports firmware updates via USB or network interfaces, ensuring adaptability to evolving Industry 4.0 frameworks. Bently Nevada's global service network provides NIST-traceable calibration and lifecycle support, aligning with ISO 17025 guidelines. Optional corrosion-resistant coatings and explosion-proof enclosures extend its use in offshore drilling rigs or sulfur-rich environments, solidifying its role in safeguarding operational integrity.
