For example, by analyzing 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, maintenance can be arranged in advance to avoid production interruption caused by sudden equipment failures.

• Compressor Status Monitoring: In petrochemical production, compressors are core equipment. The 135137-01 module is connected to sensors at key parts of the compressor, such as installing vibration sensors and displacement sensors at the compressor bearings to collect vibration and displacement signals in real-time. Through the analysis and processing of these signals, potential fault hazards such as bearing wear and rotor imbalance can be found in time. For example, when it is monitored that the bearing vibration increases abnormally or the shaft displacement exceeds the normal range, the module quickly triggers an alarm, reminding operation and maintenance personnel to conduct timely inspection and maintenance, arrange maintenance plans in advance, avoid production interruption and safety accidents caused by compressor failures, and ensure the continuity and safety of the petrochemical production process.

• Reactor Stirring Shaft Position Monitoring: For reactors in petrochemicals, whether the position of the stirring shaft is normal directly affects the uniformity and stability of the reaction. The 135137-01 module is connected to the rotary position sensor installed on the stirring shaft of the reactor to monitor the position change of the stirring shaft in real-time. Once the stirring shaft has abnormal conditions such as deviation or jamming, the module can timely transmit data to the control system, trigger an alarm and take corresponding control measures, such as adjusting the stirring speed or stopping stirring, to prevent serious problems such as reaction out of control and equipment damage caused by the stirring shaft problem, ensuring the safe and stable progress of the reaction process.

• Generator Set Monitoring: In power stations, real-time monitoring of parameters such as vibration and displacement of generator sets is crucial. The 135137-01 module is connected to multiple sensors, such as installing eddy current displacement sensors and vibration sensors on the shaft system of the generator set, collecting various position-related data during the operation of the generator set, and transmitting them to the background monitoring system at high speed. Based on these data, engineers can accurately analyze the operating status of the generator set and adjust operating parameters in a timely manner. For example, when abnormal vibration of the shaft system or displacement exceeding the allowable range is found, the load, lubrication and other parameters of the unit can be adjusted to prevent serious faults such as blade fracture and abnormal vibration of the shaft system, ensuring the stable supply of power production.

• Substation Equipment Monitoring: For important equipment such as transformers and circuit breakers in substations, the 135137-01 module can be connected to corresponding sensors to monitor parameters such as the position of the transformer tap changer and the opening and closing status of the circuit breaker. Once there is an abnormality in the equipment operating parameters, such as incorrect position of the transformer tap changer or improper opening and closing of the circuit breaker, the module timely transmits data and triggers an alarm, reminding operation and maintenance personnel to check and handle it, avoiding large-scale power outages caused by equipment failures, and ensuring the safe and stable operation of the power system.
