Schaumburg, Ill. Omron Electronic Components developed the D6F-W and D6F-V 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 1 m/s and the D6F-W04A1 a range of 0 to 4 m/s. Both exhibit a ±5% full-scale repeatable accuracy, while the D6F-V measures a flow range of 0 to 3 m/s with a ±10% full-scale repeatable accuracy. Both versions are offered as a standard product and arrive 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, which would restrict the flow path and impair the accuracy of measurement. 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 patented dust segregation system (DSS) is over 99% efficient in a variety of applications.
The D6F-W series operates on a supply voltage of 10.8 to 26.4 Vdc while consuming 15 mA maximum. Their output signal is 1 to 5 Vdc (non-linear) with load resistance of 10 kΩ minimum. The 9 x 20 x 39-mm case is composed of molded thermoplastic and connection is made through a three-pin connector. The D6F-W operates from -10 to 60°C with no ice or condensation. The D6F-V series operates on a supply voltage of 3.15 to 3.45 Vdc while consuming 15 mA maximum. Their output signal is analog 0.5 to 2 Vdc (non-linear) with load resistance of 10 kΩ minimum. The 8 x 13 x 24-mm case is composed of molded thermoplastic and connection is made through a three-pin connector. The D6F-W operates from -10 to +60C with no ice or condensation.
