FMA904R-V1

The FMA904R-V1 from Omega is a 0 to 5000FPM, remote probe, 0 to 5VDC output FMA900A series air velocity transmitter with built-in relay. The FMA904R measure air velocity and provides an analogue output proportional to the air flow and one SPST relay contact closure 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. It is used in research and development labs, HVAC applications, exhaust/ ventilation hoods and other manufacturing processes. The sensor probe available in remote 305mm (12") probe configuration with 4.5m (15') of shielded cable.
