MonoDAQ IEPE Acceleration Sensor Amplifier MonoDAQ-E-ACC

High precision vibration measurements are best done with an IEPE accelerometer. MonoDAQ 1xACC provides high quality signal conditioning for IEPE sensors. Data is transfered over EtherCAT to a PC running powerful and easy to use DEWESoft data acquisition software.
