Description

The SY342 is a digital windmill-type anemometer designed for precise measurement of air flow velocity. It uses a 3-cup sensor design that is maintenance-free and provides excellent accuracy over a wide measurement range. The electrical output is proportional to wind speed, enabling direct integration with the SY300 frame's data acquisition interface and PID controller for closed-loop air flow control experiments. The sensor can be mounted externally or within a wind tunnel setup for versatile experimental configurations.
