Amper is a strong choice for job shops and contract manufacturers needing a broader FactoryOps platform — not just machine monitoring. PLC connectivity provides more depth than pure current-sensing competitors.
Plex is the right choice for mid-market discrete manufacturers wanting machine monitoring as part of a broader cloud MES/ERP investment — particularly in automotive supply chain environments where Plex has deep vertical expertise.
