Hoofddorp, The Netherlands: Omron has added three new models to its D6F range of precision MEMS based air/gas mass flow and velocity sensors, to enable their use in a wider range of applications. Offering high-precision monitoring of airflow at three litres per minute (LPM), the D6F-03A3-000 is ideal for industrial applications, especially pressurised cable monitoring systems and pick and place machines in industrial automation. Advantages include compact size of 37 x 8 x 17 mm, low current draw of just 15 mA, and stable amplified analog output across the full scale. The exceptionally compact size of this device makes it suitable for bypass configurations, enabling use with much higher total air/gas mass flow rates.
Omron is also offering its higher flow rate series with an RCπ screw port style connection. The new A6 range, designated as D6F-10A6-000, D6F-20A6-000 and D6F-50A6-000, shares the other features of the existing A5 sensors, and is ideal for measuring air/gas mass flow rate with high repeatability, at flow rates of up to 10, 20 and 50 LPM respectively. Both the A5 and A6 style sensors give precise detection of mass flows with a high repeatability of up to +/-0.2% and an accuracy of +/-3% full scale deflection.
The third addition to the range, the D6F-V03A1, is a highly efficient, low cost MEMS flow velocity sensor ideally suited to applications such as building ventilation, clogged air intake filter detection and general detection of correct fan function. It has a compact size of 24 x 14 x 8 mm and can measure air flow velocity from 0 to 3 m/sec with an accuracy of +/-10% full scale deflection. The sensor’s key attribute is its built in Dust Segregation System (DSS) which separates up to 99.5 % of dry air borne particulate matter (simulation result) helping to maintain performance characteristics of the sensor over its lifetime.
