Key Features and Advantages

Absolute Positioning Technology: The BENTLY 3500/42-01-00 138708-01 eliminates reliance on reference marks by providing continuous absolute shaft angular position data. This feature simplifies installation and ensures accurate synchronization in high-speed machinery like gas turbines and compressors.

 

High-Precision Measurement: With ±0.05° accuracy and a wide speed range (0–60,000 RPM), the module detects subtle rotational deviations critical for analyzing gearbox alignment, bearing health, and overspeed conditions. Its high input impedance (10 kΩ) minimizes signal distortion from long cable runs.

 

Rugged Environmental Performance: Rated for extreme temperatures (-40°C to +85°C) and certified for hazardous areas (ATEX Zone 0/1/2), the module excels in petrochemical plants, offshore platforms, and other harsh industrial settings. Its stainless steel housing resists corrosion and mechanical stress.

 

Programmable Flexibility: Users can configure each channel via the 3500 Rack Configuration Software to monitor rotational speed, phase angle, or position. Customizable alarm thresholds and digital outputs (NPN/PNP) enable tailored responses to critical conditions, such as shaft misalignment or overspeed events.

 

Seamless System Integration: Native support for Modbus RTU and RS-485 protocols facilitates direct integration with PLCs and DCS systems. For Ethernet connectivity, the module works seamlessly with the 3500 EGD Communication Gateway, enabling data exchange with cloud-based predictive maintenance platforms.

Application Areas

The BENTLY 3500/42-01-00 138708-01 is widely deployed across industries to ensure machinery reliability and operational safety:

 

  • Power Generation: Monitoring steam turbines and generators for rotational speed and phase synchronization to prevent catastrophic failures. Its ATEX certification ensures compliance with explosive environment standards.
  • Petrochemical: Protecting compressors and pumps by detecting shaft misalignment or bearing wear in real time. The internal termination design simplifies wiring in hazardous areas where panel access is limited.
  • Manufacturing: Ensuring precision in high-speed motors and gearboxes, critical for quality control in automotive and packaging industries. The module’s high-speed capability (60,000 RPM) supports advanced robotics and CNC machinery.
  • Marine and Offshore: Safeguarding propulsion systems and offshore platforms with its rugged design and compliance with DNV and ClassNK certifications.

 

By integrating with BENTLY 3500 Series racks and complementary modules (e.g., 3500/22M Keyphasor), the BENTLY 3500/42-01-00 138708-01 forms a comprehensive machinery health monitoring system, delivering actionable insights for predictive maintenance strategies.
