SMC PFM750 Series Flow Switch, 24V DC Maximum Supply Voltage, 50L/min Maximum Flow Rate - PFM750S-F01-B

This flow switch is a compact digital monitor designed to measure and control gas flow in pneumatic systems. It provides real-time visual feedback via a two-colour LED display and issues switching signals to external control circuits. Suited to dry air and inert gases, it operates within typical industrial ambient and fluid temperature ranges and integrates an adjustable valve for on-site flow setting.

Features and Benefits:

• 1-50 l/min flow range supports fine control for dry gases
• 24 VDC supply enables low-voltage system integration
• PNP open-collector outputs allow direct PLC interfacing
• LED two-colour display gives immediate flow status indication
• 80 mA maximum load current minimises power draw on circuits
• Internal response time selectable down to 50 ms for fast detection

Applications

• Suitable for monitoring pneumatic lines in assembly cells
• Ideal for detecting flow loss in plant air distribution
• Used with CO2 processes requiring reduced range settings
• Can be used for in-line flow control of inert gas feeds
• Suitable for integration in compact machine panels

What fluids can it measure reliably?

It is specified for dry air, N2, Ar and CO2 with air quality meeting ISO 8573-1:2010, classes 1.2 to 1.6.2.

How is the flow threshold adjusted on-site?

Adjustment is effected with the integrated flow adjustment valve and the digital set function visible on the LED readout.

What protection is provided for the switch outputs?

Outputs include short-circuit and overcurrent protection and are rated for 80 mA maximum load.

What environmental limits should be observed for reliable operation?

Operate between 0°C and 50°C with 35-85% RH (no condensation)

storage limits differ from operating ranges.
