In recent years, with the continuous advancement and development of science and technology, in the field of machinery, large-scale mechanical equipment such as wind power generation equipment, numerical control machine tools, etc. are also moving in the direction of high precision and high efficiency. Intelligent mechanical fault diagnosis systems have emerged and are widely used. .
The intelligent mechanical fault diagnosis system is a system solution that uses advanced sensor technology to monitor the operation status of the mechanical equipment in real time and then uses the intelligent software system to perform accurate equipment fault diagnosis so as to realize intelligent health monitoring and management of machinery. The complexity of the structure and mechanism of the mechanical equipment itself, the complexity of the operating environment, and the complexity of the work tasks make it difficult to troubleshoot mechanical equipment. The intelligent mechanical fault diagnosis system can effectively reduce the number of unplanned shutdowns, realise more accurate maintenance, and ensure the healthy operation of machinery and equipment through real-time condition monitoring and fault diagnosis of mechanical equipment.
West Malaysia (Xiamen) Technology Co., Ltd. (FATRI) has been using its advanced sensor technology advantages and artificial intelligence calculations, focusing on the research, development and application of mechanical intelligent fault diagnosis package, as well as continuous R&D and design through continuously updated application requirements. Manufacture more new sensors.
Vibration failure is the main manifestation of mechanical failure. The symptoms of vibration and its spectral characteristics are the best means to reflect the characteristics of failures and are most conducive to fault diagnosis. Recently, FATRI has introduced two new types of vibration sensors to further enhance its mechanical fault diagnosis package! Further help to achieve vibration monitoring and health management of large-scale mechanical equipment such as wind power generation equipment and numerical control machine tools, helping to achieve great economic and social benefits. Let's take a look at these two vibration sensors.
Low-frequency piezoelectric vibration sensor
FATRI's latest SA0219-H low-frequency vibration sensor belongs to the piezoelectric acceleration sensor series. It measures vibration by measuring the acceleration signal generated by the measured object and converting it into an electrical signal. It can be used for low-frequency vibration monitoring in the front section of the main bearing of the wind turbine and the input shaft of the gearbox, etc. The universal type is strong.
SA0219-H adopts the base wedge-shaped self-locking shear structure design first developed by Xirenma Group. Its contact stiffness is greatly improved, the resonant frequency is greatly improved, and the linearity is good. All the indexes have reached or surpassed the current popular designs. At the same time, this product uses a stainless steel overall seal design, with superior waterproof and corrosion resistance. In addition, it not only applies to the vibration monitoring of various parts of wind turbines, but also supports the vibration monitoring of various types of industrial equipment. It has the following features:
Piezoelectric acceleration sensor
Low frequency response
Good temperature drift characteristics

Popular frequency piezoelectric vibration sensor
FATRI's latest SA10 frequency piezoelectric vibration sensor belongs to the piezoelectric acceleration sensor series and can be used for vibration monitoring of gear box outer ring gear, gear box output bearing, front and rear bearing of generator in wind power generating set. , Frequency bandwidth, universal type.
Like the SA10, the base wedge-shaped self-locking shear structure designed by the Western Horse Group was adopted. At the same time, this product uses a standard military connector, the shell is designed with a 316L stainless steel overall seal, with superior waterproof and corrosion resistance. In addition to the vibration monitoring of wind turbines in various parts of the wind, it can also be widely used in aerospace, rail transportation, petroleum and petrochemical, industrial manufacturing and other areas of equipment fault monitoring, has the following characteristics:
Sealed package
High corrosion resistance
Broadband
Locked hole
