CN0540 was designed specifically to work with high performance sensors (typically >100dB dynamic range) and has a tested and verified signal chain to measure the highest performance vibration data. The AD7768-1 24-bit ADC can sample up to 256 KSPS.
Most other IEPE DAQ solutions are ac coupled, being based on IEPE alone this is expected as piezo sensors can’t detect down to dc. However, MEMS devices can and these can also be used with CN0540.
This means CN0540, whilst optimized for ac performance, offers dc coupling allowing tilt and inclination as well as very low frequencies to be reliably detected. This is critical for slowly rotating machines found in paper/mill, food/beverage, power generation and wind turbine applications etc.
