Description

Find how an anemometer works on this link.

The FMA900A series measures air velocity and provides an analogue output proportional to the air flow. A single relay contact closure is also provided, for high alarm operation. The alarm set point is adjustable from 0 to 100% of the air flow range. The unit comes with one green power LED, and one red LED for alarm indication. The FMA900A Series are used in research and development labs, HVAC applications, exhaust/ventilation ducts and other manufacturing processes. The 300 mm long, 6.35 mm diameter stainless steel sensor probe can either be supplied fixed to the main housing or remote, with 4.5 metres of screened cable. A shorter (95 mm long) probe is also available as an option. The sensor probe can be easily installed to the required depth in ducts or pipework with a standard compression fitting. See order table below.
