IV. Functions and Working Principles
A. Vibration Signal Acquisition and Conversion
The operation of TM202-A00-B00-C00-D00-E00-G00 starts with the acquisition of equipment vibration signals. Its internal piezoelectric sensor serves as the core component. When the equipment generates vibration, the piezoelectric sensor is subjected to mechanical stress. According to the piezoelectric effect, piezoelectric materials generate charges on their surfaces when subjected to external forces, and the amount of charge is proportional to the applied external force. Therefore, changes in the vibration amplitude and frequency of the equipment will be converted into corresponding changes in electrical signals through the piezoelectric sensor. These original electrical signals are relatively weak and mixed with various noises, and then enter the signal conditioning circuit of the transmitter. In the signal conditioning circuit, through a series of processing processes such as amplification and filtering, the original electrical signals are converted into stable and standard output signals, such as 4-20mA current signals, 0-10V voltage signals, or digital signals output through the RS232 interface, for subsequent equipment to perform data acquisition and analysis.
B. Data Transmission and Application
The signals after conversion and conditioning can be transmitted to external equipment in multiple ways. When using 4-20mA or 0-10V analog signal output, it can be directly connected to various data acquisition modules, PLC (Programmable Logic Controller) analog input modules, and other equipment. After receiving the signals, these equipment can analyze and process the vibration data according to preset algorithms and thresholds, such as judging whether the equipment is in normal operating status and sending alarm signals in a timely manner when the vibration value exceeds the normal range. If output through the RS232 digital interface, it can be connected to computers, data recorders, and other equipment. On the computer side, users can use professional monitoring software to conduct real-time monitoring, storage, and analysis of vibration data, as well as generate various reports and charts, providing detailed data support for the long-term maintenance and management of equipment. For example, through trend analysis of vibration data over a period of time, the time point when the equipment may fail is predicted, maintenance plans are arranged in advance, and the risk of sudden equipment failures is reduced.
