SPECIFIC ALGORITHMS

大多数工业机械都显示出一个可测量的警告信号，表明故障正在发生，如轴承磨损、齿轮开裂、失去润滑或不平衡状况。关键机械的连续振动监测被广泛认为是在故障发生前检测此类故障的有效手段。智能振动传感器结合了传统的振动传感器、专用电路、先进的微处理器技术和有针对性的算法，能够提供有用、准确和及时的信息机器的健康状况。Most industrial machinery exhibit a measurable warning sign that a fault, such as a worn bearing, cracked gear, loss of lubrication,or an unbalance condition is developing. Continuous vibration monitoring of critical machinery is widely regarded as an effective means of detecting such faults before a failure occurs.Smart vibration sensors combine traditional vibration sensors,specialized circuitry, advanced microprocessor technology,and targeted algorithms to provide useful, accurate, and timelyinformation regarding a machine’s health.

往复式压缩机在短时间内会出现破坏性故障。由于杆螺母开裂、螺栓松动或间隙过大而导致的机械松动可能迅速恶化，导致压缩机灾难性故障。在极端情况下，这种情况可能在几分钟内发生。专利的往复式机械保护器（RMP）检测真实的峰值加速度，计算超过特定阈值的影响，并根据压缩机速度处理数据，以4-20毫安信号量化机器的健康状况。Reciprocating compressors can develop devastating faults in a short period of time. Mechanical looseness caused by a cracked rod nut, loose bolt, or excessive clearance can deteriorate quickly resulting in catastrophic failure of the compressor. In extreme cases, this can happen in a matter of minutes. The patented Reciprocating Machinery Protector (RMP) detects true peak acceleration, counts impacts above specific thresholds, and processes the data based on compressor speed to quantify the machine’s health in terms of 4-20 mA signal.
