Function Features

• Multi – functional Channel Programming: Channels are programmed in pairs, and each channel can be set to perform functions such as impulse acceleration, acceleration 2, reciprocating velocity and low – frequency reciprocating velocity via the 3500 rack configuration software. It can run two different or the same functions at the same time to meet various vibration monitoring needs of reciprocating compressors.
• Precise Vibration Data Acquisition: Equipped with advanced signal processing technology, the module has high sensitivity and can detect even tiny impulse vibrations. It can measure multiple parameters including peak velocity, peak impulse, average velocity and average impulse, with a measurement accuracy of ±0.5% of reading, ensuring the reliability of the collected vibration data.
• Customizable Dual – level Alarm Settings: Users can set independent alert and danger thresholds for the static values generated by each channel according to actual working conditions. Once the monitored vibration parameters exceed the set thresholds, the module will trigger the corresponding alarm relay outputs to promptly warn of potential equipment risks.
• Seamless System Integration: With RS – 232, RS – 485 and Ethernet communication ports, the module can be smoothly integrated into existing industrial automation systems. This compatibility not only realizes seamless transmission of monitoring data but also reduces the cost of system transformation and upgrade for enterprises.
• Durable and Low – maintenance Performance: Made of industrial – grade corrosion – resistant and wear – resistant materials, the module can maintain stable performance during long – term operation without frequent calibration and adjustment. Its compact structure also facilitates quick installation and fixing, reducing the time and cost of equipment downtime and maintenance.

Application Scenarios

• Oil and Gas Industry: It is widely used in reciprocating compressors in onshore oil and gas gathering stations, offshore drilling platforms and pipeline compression stations. It monitors the vibration of key parts of compressors in real time to avoid safety accidents such as oil and gas leakage caused by equipment damage due to abnormal vibration and ensures the continuity of oil and gas extraction and transportation.
• Chemical Industry: It is deployed on reciprocating compressors and related reciprocating equipment in chemical plants. These devices are critical to material mixing, reaction and transportation in chemical production. The module can timely detect abnormal vibration of the equipment, prevent production interruptions or dangerous chemical leakage accidents caused by equipment failure.
• Power Generation Industry: It is applied to reciprocating auxiliary equipment such as air compressors and feed pumps in thermal power plants and gas – fired power plants. By monitoring the vibration status of these auxiliary equipment, it ensures the stable operation of the entire power generation system and avoids large – scale power outages caused by the failure of key auxiliary equipment.
• General Manufacturing Industry: It is installed on reciprocating machinery in metallurgical, papermaking and other factories. It monitors the vibration parameters of key components of the machinery. Maintenance personnel can formulate targeted maintenance plans based on the data provided by the module, extend the service life of the equipment and reduce economic losses caused by unplanned production shutdowns.
• Refrigeration and Air Conditioning Industry: It is used for vibration monitoring of reciprocating compressors in large – scale central air conditioning systems and industrial refrigeration units. Stable operation of these compressors is the key to ensuring the refrigeration effect. The module can timely find potential faults of the compressors and avoid the paralysis of the entire refrigeration system due to compressor failure.
