Systemair OPTIMA-R-FM-080-SA - Air Flow Mesurement transmitter (OEM Siemens)

The air flow measurement device OPTIMA-R-FM is intended for continuous reading of the air flow volume in the circular-shaped ventilation ducts. The air flow volume is interpreted and transmited by the analog signal or by the bus communication. Highlights • Precise continuous air flow volume reading • Measurement data transfer via analog signal, or Bus line: Modbus or BACnet • Compact dimensions • No maintenance Design OPTIMA-R-FM consists of the circular-shaped casing from galvanized steel with rubber gaskets on the spiro-duct connection part. Inside it is equipped by the air flow measurement probe of dynamic ΔP type. Outside the air flow transmitter is attached and connected to the measurement probe by flexible impulse tubes.
