March 13, 2008 — Omron Electronics Components Business—Europe (OCB-E) is now offering to customize its D6F MEMS mass flow sensor products to suit individual customer requirements in terms of flow rate and non-corrosive gas type.
The D6F flow sensors measure gas velocity and mass flow rate using a proprietary 3D MEMS structure to give good performance in terms of resolution and repeatability even at very low flow rates, according to company claims. The tiny MEMS flow chip uses changes in the temperature distribution around its central heating element to accurately detect the tiniest air flow.
The sensors offer a repeatability of up to +/- 0.1% and accuracy to +/-3% of full-scale deflection on the most accurate parts. The D6F-V, D6F-W, and D6F-P units are aimed specifically at detecting clogged air intake filters in ventilation and cooling systems and feature a patent-pending dust segregation system.
Omron Electronics can provide mass flow sensors suitable to measure any flow rate from 1mm per second to 40m per second or 1LPM to 50LPM of most non-corrosive gases. The customization service is subject to a minimum order size of about 100 sensors.
