MEMS flow sensors measure air
The dust-resistant design of Omron's D6FW and D6FV MEMS flow sensors prevents contamination of the sensor chip and build up of dust.
Omron Electronic Components has released the D6FW and D6FV series of MEMS flow sensors which have the ability to measure air velocity and volume The D6F-W01A1 measures a flow range of 0 to 1m/s and the D6F-W04A1 a range of 0 to 4m/s

Rapid alignment is ensured by an alignment aid that uses intuitive LED indication and instantly shows whether adjustment is correct or incorrect.
Both exhibit a +/-5% full-scale repeatable accuracy.
The D6FV measures a flow range of 0 to 3m/s with a +/-10% full-scale repeatable accuracy.
Both versions are offered as a standard product and arrive optimally calibrated per factory specifications.
To enable the sensors to perform in a dust filled environment, a dust-resistant design prevents both contamination of the sensor chip and build up of dust that would restrict the flow path and impair the accuracy of measurement.
This housing design is based on a centrifugal principle to segregate particulates from the air.
Most particulates cannot pass through the sensing area and are discharged through the exhaust route.
A clogged filter detection sensor monitors the pressure drop over the filter and emits a warning signal indicating the need for filter replacement when the drop exceeds a given threshold.
This Dust Segregation System (DSS) is over 99% efficient in a variety of applications.
The D6FW series operates on a supply voltage of 10.8 to 26.4V DC while consuming just 15mA maximum.
Their output signal is 1 to 5V DC (nonlinear) with load resistance of 10kohm minimum.
The 9 x 20 x 39mm case is composed of moulded thermoplastic and a connection is made through a three-pin connector.
The D6FW operates from -10 to +60C with no ice or condensation.
The D6FV series operates on a supply voltage of 3.15 to 3.45V DC while consuming just 15mA maximum.
Their output signal is analogue 0.5 to 2V DC (nonlinear) with load resistance of 10kohm minimum.
The 8 x 13 x 24mm case is composed of moulded thermoplastic and a connection is made through a three-pin connector.
The D6FW operates from -10 to +60C with no ice or condensation.
"When considering the potential for a clogged filter shutting down an entire computer server, clean room or HVAC equipment, the D6FW sensor provides a cost-effective method to keep these systems running at peak efficiency", said Cami Marsh, Marketing Communications Co-ordinator of Omron Electronic Components.
