The FS-521 paddle switch is intended to monitor air flow within a duct and provides a switched output on detection of either a specific air velocity or flow failure.
The sensitivity can be adjusted by means of a screw inside the calibration unit. The blade can be trimmed to increase sensitivity if necessary.
