SMC PF3A8#H-L pneumatic flow switch

The PF3A8#H-L is the latest addition to SMC’s flow switch range. Designed to cover a large flow measurement range, this modular flow sensor features a clear and easy-to-read 4-screen display.

Offering a 100:1 flow ratio, the PF3A8#H-L can detect small leaks (10 Lpm or more), monitor main line air consumption (up to 2000 Lpm) while simultaneously measuring air pressure and temperature.

The 3-colour and 2-line screen display can rotate in increments of 90° allowing operators to take notes and set the flow switch while checking the measured value. It also has IO-link compatibility, together with switchable NPN/PNP output.

Through a bore-type structure made of aluminium alloy, the PF3A8#H is said to be highly durable. The modular design also reduces the required installation space, piping and wiring work. The brackets allow the flow switch to be retrofitted on steel pipes systems and into legacy SMC air service units. All the process data (flow, pressure, temperature) as well as identification and configuration data for the PF3A8#H-L is transmitted with a single M12 standard connector.
