Bi-directional flow sensor offers reliable output performance

15 October 2007

Omron Electronic Components new MEMS-based D6F-P air flow sensor delivers uni- or bi-directional sensing with amplified output in a highly compact package. SUitable for flow rate monitoring and dumper control in HVAC/VAV applications, it also acts 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.

The compact sensor measures just 7 x 35 x 17.2 mm (L x W x H) and comes with lead terminals for PCB mounting or as a connector option. In a bypass configuration, the D6F-P can measure flow higher than its own capability and can also 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 litre/min at an output voltage of 0.5 to 2.5V with an accuracy of +/-5% full-scale deflection.
