I need to have a standalone system to capture vibrations off a Diesel Prime Mover / reciprocating machinery and run a FFT on the same.
The arrangement in my mind is an IMI Piezo Sensor / model number #603C01 connected to an ADC / MCC172 Board OR a CN0540 (Analog Devices). The latter, SPI / 24 bits data to be connected to a FPGA Board for processing the FFT. The FFT data to reach a LCD screen / preferably a Tablet.
The LCD Display to show the graph of the frequency domain ONLY in real time.
Products like this are essentially a usb soundcard with signal conditioning for an ICP sensor
Finding a widget that converts an ICP sensor to audio line level may be one option then just use a spectrum analyzer app on a tablet.

I haven't used one, just showed up on a quick google search. If I was working on this I would just try getting raw data to help define requirements and you are clearly on the right path. Thanks for sharing your project, its interesting to see what's happening in 2023. I did a quick search for bearing vibration analysis, here is a device that popped up. Maybe there are some helpful hints even if the product isn't a fit.
