Description

• Technical Specifications
  • Input Parameters: Equipped with 4 channels that specifically accept proximity transducer signals. The standard input impedance is 10 kΩ. The sensitivity varies by measured parameters, with 3.94 mV/μm or 7.87 mV/μm for radial vibration, thrust position and eccentricity, 0.394 mV/μm or 0.787 mV/μm for differential expansion, and 40 mV/μm or 80 mV/μm for REBAM.
  • Frequency Response: It has different frequency response ranges based on the monitoring function. For radial vibration, the direct frequency response ranges from 4 Hz to 4 kHz and the gap frequency response is 0.09 Hz. For thrust position and differential expansion, the direct frequency response is 1.2 Hz and the gap frequency response is 0.41 Hz. The frequency range for REBAM spike is programmable from 0.152 Hz to 8678 Hz.
  • Power and Output: It provides a -24 VDC power supply for transducers and has a typical power consumption of 7.7 W. The buffered outputs have an impedance of 550 Ω and are protected against short circuits to ensure stable signal transmission.
  • Alarm and Delay Settings: Alarm setpoints can be adjusted within 0 – 100% of the full – scale range with an accuracy of ±0.13%. The alert delay can be set from 1 second to 60 seconds, and the danger delay ranges from 0.1 seconds to 60 seconds.
  • Physical and Environmental Traits: The main module has dimensions of 241.3 mm × 24.4 mm × 241.8 mm and a weight of 0.91 kg. The operating temperature ranges from -30 °C to +65 °C for standard I/O and from 0 °C to +65 °C for barrier I/O.
  • Measurement Accuracy: The typical measurement accuracy is ±0.33%, and the maximum accuracy for most measured values is ±1%, which guarantees the reliability of the monitoring data.
• Function Features
  • Multi – function Configurable Channels: The 4 channels can be programmed to perform multiple monitoring functions. The channels operate in pairs, allowing a maximum of 2 functions to run at the same time. Users can flexibly configure the module according to specific monitoring needs of different equipment.
  • Programmable Alarm Mechanisms: Users can set alert setpoints for each active static value derived from signal conditioning and danger setpoints for any two of the active static values. This customized alarm setup ensures timely warnings for different levels of equipment abnormalities.
  • Protected and Stable Outputs: The buffered outputs are designed with short – circuit protection. This design prevents damage to the module and related circuits caused by short – circuits in the output loop, enhancing the overall operational stability of the monitoring system.
  • Intuitive Status Indication: The front panel is equipped with LED indicators including OK, TX/RX and Bypass. These indicators directly display the module’s power status, signal transmission status and bypass status, enabling maintenance personnel to quickly identify the module’s working condition.
  • Seamless Rack Integration: It communicates and integrates with the 3500 series rack system through the dedicated backplane. It can work in coordination with other modules in the rack and is compatible with the 3500 rack configuration software for parameter setting and function configuration.
• Application Scenarios
  • Power Generation Industry: It is widely used in thermal, hydroelectric and nuclear power plants to monitor key equipment such as steam turbines, generators and feedwater pumps. It tracks parameters like rotor radial vibration and thrust position, timely detecting faults such as rotor imbalance and bearing wear to avoid major power generation accidents.
  • Oil and Gas Industry: Deployed on offshore drilling rigs, pipeline compressors and gas turbines. It monitors the vibration and position of rotating parts in these equipment under harsh conditions such as high pressure and corrosion, preventing equipment damage caused by factors like pipeline blockages and rotor misalignment.
  • Petrochemical Industry: Applied to reciprocating compressors, reaction tower auxiliary pumps and gearboxes in chemical plants. It monitors parameters such as differential expansion and eccentricity of rotating shafts, helping to find faults such as seal leakage and valve wear early and ensuring the safety of chemical production processes.
  • Aerospace Field: Used for monitoring the rotating components of aircraft engines and transmission systems. It accurately measures vibration and position parameters during high – speed operation of the equipment, providing data support for the maintenance and fault diagnosis of aerospace equipment and ensuring flight safety.
  • General Manufacturing Industry: Installed on large – scale rotating machinery including industrial pumps, fans and centrifuges in manufacturing workshops. It conducts real – time monitoring of the equipment’s operating status, guides maintenance personnel to carry out targeted maintenance, and reduces production downtime caused by sudden equipment failures.
