Bently 3500/25 149369-01

Description

• Technical Specifications
  • Power Parameters: It adopts a 24V DC power supply with a maximum acceptable voltage of 30V DC, a power consumption of 3.2 watts, and a maximum input current of 20mA, which has minimal impact on the overall power load of the 3500 rack.
  • Input Performance: It has two input channels. The non-isolated I/O module accepts input voltages ranging from -0.8V to -21.0V, while the isolated I/O module supports an input voltage range of +5V to -11V with an input impedance of 1 MΩ. It has an automatic threshold with a small signal amplitude of 2V peak-to-peak and a minimum frequency of 120 rpm.
  • Output Performance: It provides 4-20mA DC output signals. It is equipped with two buffered outputs accessible via both front-panel coaxial connectors and rack rear European-style connectors, ensuring flexible signal access for different installation needs.
  • Measurement Indicators: It covers a frequency range of 0.1Hz to 50kHz and achieves a measurement accuracy of ±0.1% of full scale. The manual threshold applies to any input above 0.017Hz, with a small signal triggering amplitude of 500mV peak-to-peak and user-selectable hysteresis ranging from 0.2V to 2.5V.
  • Physical and Environmental Indicators: It weighs 0.34kg and has dimensions of 76.2mm × 107.9mm × 38.1mm. It operates and stores at temperatures between -40°C and +85°C, works normally in environments with a maximum 95% non-condensing humidity, and has an IP67 protection level that adapts to harsh industrial environments.
• Function Features
  • High-Precision Digital Signal Conversion: It accurately converts analog signals from proximity probes or magnetic pickups into digital keyphasor signals. These signals can precisely indicate the alignment of the keyphasor mark on the shaft with the transducer, laying a solid foundation for accurate time measurement and phase analysis of rotating machinery.
  • Strong System Compatibility and Replacement Capability: It can directly replace the older keyphasor module and maintain full compatibility with existing legacy systems. It can be seamlessly integrated with other modules in the 3500 series and can also connect with the 3500 system configuration software, reducing the cost of system upgrades and transformation for enterprises.
  • Flexible Threshold Configuration: It offers both automatic and manual threshold options. The manual threshold allows users to adjust the hysteresis according to actual application scenarios, which enables the module to adapt to different types of rotating machinery and complex working conditions, enhancing the flexibility of its use.
  • Redundant Operation Support: It can be deployed in triple modular redundant configurations. Two modules work in parallel to output primary and secondary keyphasor signals. This redundant design avoids monitoring interruptions caused by single-module failures and significantly improves the reliability and stability of the entire machinery protection system.
  • Dual-Channel Efficient Signal Processing: The dual-channel design allows it to process two groups of keyphasor signals simultaneously. The 3500 machinery protection system can accept up to four keyphasor signals in normal configuration and up to eight in paired configuration, meeting the monitoring needs of multi-shaft or complex rotating machinery.
• Application Scenarios
  • Power Generation Industry: It is installed on steam turbines, generators and water pumps in thermal, hydro and nuclear power plants. It provides precise keyphasor signals to monitor the rotational state of the equipment shafts. It helps detect abnormal shaft operation in a timely manner to prevent serious accidents that may lead to power outages.
  • Oil and Gas Industry: It is applied to offshore drilling rigs, pipeline compressors and oil pumping units. It can work stably in harsh environments such as high temperature, high pressure and high humidity. It monitors the rotating components of the equipment, ensuring the safety and continuity of oil and gas extraction, transportation and processing processes.
  • Petrochemical Industry: It is used to monitor the operating status of rotating machinery such as reaction kettle agitators and gearboxes in refineries and chemical plants. Its high-precision signal conversion and stable performance can promptly warn of potential faults in the equipment, avoiding safety hazards such as leaks caused by equipment failures.
  • Metallurgical Industry: It is deployed on rolling mills, blast furnace fans and air compressors in steel mills. It can withstand high-temperature and dusty working environments. It continuously monitors the shaft rotation parameters of the equipment, providing data support for preventive maintenance and reducing production downtime caused by equipment malfunctions.
  • Heavy Equipment Manufacturing: It is integrated into the testing process of large motors, fans and other products. It accurately collects keyphasor data during the operation of the tested equipment, helping manufacturers evaluate product performance, optimize product design details and improve the overall quality and reliability of the products leaving the factory.
