IEPE Vibration Sensor Interface for PLC Analog Input Reference Design

1 января 2018

Industrial vibration sensing is crucial part in condition monitoring necessary for predictive maintenance. Integrated Electronic Piezoelectric (IEPE) sensor is the most common vibration sensor used in industrial environment. This design is a full analog front-end for IEPE sensor interface demonstrating how to achieve flexible high-resolution, high-speed conversion with low-power and small-footprint implementation.
