FMA905R-V1-S

FMA905R-V1-S is an air velocity transmitter with a relay output and remote probe. It provides either a 0 to 5 VDC or 4/20mA analog output corresponding to the air flow range and one SPST relay contact closure corresponding to high alarm set point. The alarm set point is adjustable from 0 to 100% of the air flow range. This unit can be used in HVAC applications, R&D labs, exhaust/ ventilation hoods and other manufacturing processes. The sensor is designed based on RTD elements. The air velocity is measured by the heat loss from the RTD sensor as it cools down by the air flow. The sensor is housed in a 1/4" OD x 12" long 304 Stainless Steel tube with inch marks for ease of insertion depths.
