State where in industry a non-contact accelerometer is used, give an example.

Solution

Steam turbines, compressors, generators, and aviation engines are the principal rotating machinery. They play an important role in the development of the modern industrialized process. In addition, they are the basis equipments of some military and civilian sectors. Therefore, effective detection means can ensure their healthy and stable running. It’s also an important strategic issue, which relates to the national economy and national security and defense.

Rotating machinery faults are often shown in vibration condition, which directly response to the health condition of the equipment, and they are important indicators of equipment safety assessments. Thus, the monitoring vibration signals are the principal means for rotating machinery condition monitoring and fault diagnosis
