It describes the accelerometer sensor interfacing circuit, rms-to-dc converter and voltage to current loop converter circuit design, calibration procedure, and mounting methods. This industrial vibration transmitter output can be customized to obtain either acceleration or velocity with root mean square (rms) or peak value signal. The output of the transmitter is in current signal (4-20mA) which is proportional to the input acceleration (0-10g rms) in root mean square. The AC coupling circuit for accelerometer sensor interfacing, RMS detector and industrial current loop converter circuit are implemented in a single printed circuit boards. The prototype was made which consists of 2 pin top connector for power input (24VDC) & current output signal, stainless steel mechanical housing assembly with bottom thread connection for mounting. This loop powered acceleration vibration transmitter is employed for vibration monitoring and control applications. | | ISBN: | 0-9767985-8-1 |
