TTI, Inc. has introduced Omron’s new D6F-P MEMS-based D6F-P air flow sensor, suitable for flow rate monitoring and dumper control in HVAC/VAV (Variable Air Volume) applications. The D6F-P delivers uni- or bi-directional sensing with amplified output in a highly compact package. A key feature is its integrated, patent pending dust segregation system (DSS) which separates up to 99.5% (simulation test result) of dry air borne particulates from contaminated air helping to maintain performance characteristics of the sensor over its lifetime. The DSS is bi-directional, protecting against particulates whatever the direction of flow.

The highly compact flow sensor measures 7 x 35 x 17.2 mm (L x W x H). It comes with lead terminals for PCB mounting or with a connector option enabling increased system design flexibility. . In a bypass configuration, the D6F-P can measure flow higher than its own capability and maintain differential pressure sensing with high sensitivity and repeatability even in very low flow conditions. It comes with a uni- or bi-directional flow range of 1.0 LPM at an output voltage of 0.5 to 2.5V with an accuracy of +/-5% full-scale deflection.

The D6F-P can act as a replacement for differential pressure sensors in HVAC systems as well as medical equipment such as respirators, ventilators, Continuous Positive Airway Pressure (CPAP) and sleep apnea monitors.
