In a factory, essential, high-value, 24/7-operated machines and equipment need constant health monitoring for effective maintenance. Among the machine's health factor monitorings, vibration monitoring is the most crucial tool in a predictive maintenance program. The application of an online vibration monitoring system will help detect abnormalities, predict early damage types of machines and equipment, and overcome the following difficulties:
Sensors are available everywhere at factories, and they are present in all systems for measuring parameters such as steam pressure, pipeline temperatures, water tank level. Although there are different types and brands, the sensors usually have an output of analog signal 4-20mA and are connected to the center by a signal wire. Therefore, if the factory adopts a wireless sensor network, it will help to eliminate the difficulties of a wired network as follows:
