530 series air flow switchDetailed product description：

The 530 series air flow switch has good quality, with a sturdy and durable cast casing. The impeller and SPDT dry spring switch are made of stainless steel, which is reasonably priced and provides excellent sensitivity and reliability. The 530 air flow switch can be adjusted on-site within 400-1600FPM, and its installation is convenient and simple, requiring only two screws. The impeller is suitable for pipelines of 6 inches or larger and can be adjusted within the range of 400-1600FPM. The stainless steel impeller SPDT quick contact switch has adjustable flow rate, with a diameter of 2-8m/s for 6 "and 8" pipes. Recommended specifications: The working principle of the air flow switch is to drive a single pole double throw switch with a 7-1/2 "stainless steel impeller. The impeller speed is controlled by calibrated springs, which can be precisely adjusted to the desired operating point. Through a direct mechanical link, the impeller action is transmitted to the switch, which should also be produced by Dwyer, model 530.
