Circuit Design and Application of A High-Precision Measurement IEPE Accelerometer
With the rapid development of the environmental testing equipment industry,the demand for environmental vibration testing is increasing.Among them,the measurement of acceleration has become a key parameter for evaluating the effectiveness of vibration testing.In order to accurately obtain the acceleration value in environmental vibration testing,especially when using integrated circuit piezoelectric sensors(IEPE acceleration sensors),this paper proposes a high-precision measurement circuit design scheme for IEPE acceleration sensors.This circuit scheme aims to solve the problem of signal advance and processing in vibration testing of IEPE accelerometer.The circuit mainly includes modules such as constant current power supply,signal conditioning,signal output,power management,and noise suppression for the sensor.This circuit has successfully achieved precise measurement of IEPE acceleration sensors and has been applied in environmental vibration test boxes,providing a reliable measurement method for vibration testing,industrial monitoring,mechanical health diagnosis and other fields.
