Description

Industrial vibration sensing is a crucial process in condition monitoring, which is necessary for predictive maintenance. An integrated electronic piezoelectric (IEPE)TM sensor is the most common vibration sensor used in the industrial environment. This design is simple sensor analog front-end suitable for interfacing the IEPE sensor to integrated MSP432, allowing a compact implementation for IEPE to IO-Link interface.

Features
  • Front-end for single IEPE sensor input
  • 14-bit resolution
  • 20 kHz bandwidth
  • Uses MSP432 integrated ADC
  • 4mA fixed curent source excitation
  • ±6 V AC input, 500 kΩ input impedance
  • Wire-break detection
