Functional Features
Multi-Channel Data Acquisition

• Strong Sensor Adaptability: As a 4-channel device, 135489-04 can seamlessly connect with various types of sensors. It can be connected to Bently Nevada's own Proximitor, Seismic Transducers, and Velomitor sensors, etc. In rotating machinery monitoring scenarios, connecting to proximity sensors can collect key data such as vibration and displacement of the equipment shaft system in real-time and accurately, providing a key basis for judging the equipment's operating status; in some occasions with high requirements for equipment vibration monitoring, connecting to seismic sensors can capture subtle vibration changes of the equipment, meeting the needs of industrial production for high-precision vibration monitoring.

• Efficient Data Acquisition: The 4-channel design allows the module to collect data from multiple monitoring points at the same time, greatly improving the efficiency and comprehensiveness of data acquisition. For example, in the status monitoring of large motors, sensors at four different positions can be connected simultaneously to obtain vibration and position data during motor operation in an all-round and real-time manner, avoiding missing potential fault hazards due to single-point monitoring, and providing richer and more comprehensive data support for the overall operation status evaluation of the equipment. Each channel can monitor a frequency range of 0.1Hz to 15kHz, which can cover the frequency range of vibration and position changes of common industrial equipment, ensuring accurate capture of various dynamic information during equipment operation.

Signal Conditioning and Conversion

• Analog Signal Digitization: The module can quickly and accurately convert analog signals from sensors into digital signals, preparing for subsequent data processing and transmission. In the conversion process, high-precision A/D conversion technology is adopted to ensure that the converted digital signals accurately reflect the characteristics of the original analog signals, effectively avoiding signal distortion and providing a reliable data basis for equipment status analysis.

• Signal Filtering and Amplification: A series of conditioning operations such as filtering and amplification are performed on the collected signals. Through advanced digital filtering algorithms, noise interference in the signals can be effectively removed, and signal quality can be improved; at the same time, according to actual monitoring needs, the signals are appropriately amplified to enhance the readability and analyzability of the signals. For example, when processing weak vibration signals, through precise amplification operations, the real situation of equipment vibration can be clearly presented, avoiding misjudgment of equipment status due to weak signals.

Equipment Protection and Early Warning

• Real-Time Parameter Comparison and Alarm: One of the core functions of the module is to continuously compare the monitoring parameters with the alarm set points pre-set by the user in the 3500 rack configuration software. Once the monitored data exceeds the preset normal range, it will quickly trigger the alarm mechanism. Alarm methods include indicator light flashing, relay output, etc., which can promptly notify operators of abnormal equipment conditions, so that operators can quickly take corresponding measures, such as adjusting equipment operating parameters and arranging equipment maintenance, to prevent further deterioration of equipment failures and effectively protect the safe operation of equipment. For example, in vibration monitoring, for the normal vibration range of different equipment, two-level vibration alarm thresholds (warning and danger) can be set respectively. When the equipment vibration exceeds the warning threshold, an early warning signal is sent to remind operation and maintenance personnel to pay attention to the equipment status; when the vibration reaches the danger threshold, an emergency alarm is immediately issued to urge operators to take emergency shutdown and other measures.

• Key Data Collection and Analysis: In addition to the alarm function, 135489-04 is also responsible for collecting key information for equipment operation and maintenance. It can continuously monitor various parameters during equipment operation, and organize and store these data. Through in-depth analysis of these historical data, operation and maintenance personnel can understand the operating trend of the equipment, find potential fault hazards in advance, formulate reasonable maintenance plans, and realize preventive maintenance of the equipment. For example, through trend analysis of the long-term vibration data of the equipment, if it is found that the vibration amplitude has a gradually increasing trend, it may indicate that there are problems such as component wear inside the equipment. At this time, equipment maintenance can be arranged in advance to avoid production interruption caused by sudden equipment failures and reduce enterprise production losses.

• Integration with 3500 System: As an important part of the 3500 series monitoring system, the 135489-04 module can work with the 3500 rack and other related modules to realize comprehensive monitoring and management of multi-dimensional operating parameters of equipment. Through the 3500 rack configuration software, parameters and functions of the module can be conveniently set to ensure the efficient operation of the entire monitoring system and give full play to the powerful functions of the 3500 system. For example, in the monitoring of large compressors in petrochemical enterprises, 135489-04, in cooperation with other modules of the 3500 system, can monitor multiple parameters such as vibration, displacement, and temperature of the compressor at the same time, providing comprehensive data support for the evaluation of the equipment's operating status, timely discovering potential fault hazards, and ensuring production safety.

• External System Compatibility: With standard communication interfaces and support for multiple communication protocols, the module can be easily integrated with control systems and monitoring software of other brands. For example, it can seamlessly connect with some control systems of GE and other third-party condition monitoring software. This strong compatibility enables enterprises to build personalized industrial equipment monitoring and management systems according to their actual needs, improving the intelligence and informatization level of the production process. For example, in the digital transformation projects of some enterprises, 135489-04 can be integrated with the existing Enterprise Resource Planning (ERP) system to realize the interconnection of equipment operation data and enterprise production management data, providing a more comprehensive data basis for enterprise decision-making, helping enterprises optimize production processes and improve production efficiency.
