Series PF3A digital flow switch provides continuous quantitative values as well as switched digital outputs when set flow levels are measured. The PF3A is suitable for applications requiring a metered quantity of air, such as for supply confirmation, filling accumulation, or fixed supply consumption. The oversized PF3A display has 2 screens, with main screen flow values in red or green, while

Item PF3A703H PF3A706H PF3A712H The operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance.
Over current error The switch output load current is 80 mA or more. [Measurement mode] Measurement mode is the condition where the flow is detected and displayed, and the switch function is operating. This is the basic mode; other modes should be selected for set-point changes and other function settings.
