The Festo SFAH‑200U‑Q8S‑PNLK‑PNVBA‑M8 (P/N 8058478) is an industrial-grade thermal mass flow sensor/transmitter designed for compressed air or gas monitoring. It measures flow from 4 to 200 L/min and provides dual PNP/NPN switch outputs, analog output options, and full IO‑Link connectivity—ideal for automated pneumatic systems, diagnostic enhancements, and remote monitoring via IIoT.
