SMC PFM Series Integrated Display Flow Switch for Air 1L/min Min, 50L/min Max, Polybutylene Terephthalate PFM750S-C8-A-W

The SMC PFM750S-C8-A-W is an advanced integrated display flow switch designed for precise air flow monitoring in industrial and automation settings. Manufactured in Japan, this flow switch combines compactness and lightweight construction with rugged polybutylene terephthalate housing making it suitable for environments requiring corrosion resistance and durability.

Ideal for applications involving carbon dioxide, air, nitrogen, or argon gases, the device monitors flow rates ranging from a minimum of 1 L/min up to a maximum of 50 L/min, allowing for fine control with its minimum unit setting of 0.01 L/min.

This model features an integrated flow adjustment valve that minimizes external piping requirements and optimizes space utilization. The flow switch includes a digital display and the user can set the response time for rapid and accurate measurements. It operates at a supply voltage of 24V dc, withstands a maximum pressure of 750 kPa, and is IP40 rated for protection against ingress of solid objects.

Repeatability is maintained within ±1% of full scale or less, ensuring high accuracy for demanding industrial applications such as vacuum systems, filter congestion monitoring, and nozzle flow detection. The device has a current rating of 55mA and complies with CE standards for quality assurance.
