The PFM710-F01-E is a compact and lightweight digital flow switch developed by SMC for precise monitoring of flow conditions in industrial and laboratory applications. It is particularly suited for detecting microchip component adsorption in vacuum systems, as well as congestion in filters and nozzles.
Equipped with a 2-color digital display, the device allows operators to quickly identify irregularities at a glance. It supports a flow rate range of 0.2 to 10 L/min, with other models in the series extending up to 100 L/min.
The switch is compatible with air, nitrogen (N₂), argon (Ar), and carbon dioxide (CO₂), making it versatile for multiple environments. It provides both PNP switch output and analog output (1–5V), operates on a 24 VDC power supply, and incorporates MEMS sensor technology with an integrated flow adjustment valve for enhanced accuracy.
