OMRON Releases New Cyclone-Type MEMS Flow Sensor

September 12, 2007

The D6F-P offers high reliability and bi-directional flow monitoring for use in applications such as sensing air conditioner intake and exhaust or human breathing.


TOKYO /BUSINESS WIRE/ -- Omron Corp. has announced the release of a new MEMS flow sensor, the D6F-P, on September 14, 2007. Incorporating a unique cyclone-type Dust Segregation System (DSS), the new flow sensor is ideal for applications that require sensing of nonfiltered, ordinary air, such as 24-hour ventilation systems and energy-saving air conditioners for homes and offices. Omron will exhibit the D6F-P MEMS Flow Sensor at the CEATEC JAPAN 2007 Exhibition, which runs from October 2 (Tuesday) to October 6 (Saturday) at Makuhari Messe International Convention Complex, near Tokyo, Japan.

MEMS flow sensors are particularly sensitive to dust particles. To overcome this drawback, the new product features Omron-designed 3D flow paths that generate cyclonic flows to separate dust particles from the air using centrifugal and gravitational forces. Unlike conventional sensors that rely on an indirect-sensing method, the new D6F-P senses airflow directly and can thus help increase the precision of air conditioning equipment.

Development Background
In recent years, 24-hour ventilation systems, reducing power consumption, and environmental protection have become issues of major concern, and this has created a demand for precise measurement and control of the volume of air passing in and out of air conditioning systems. Omron's new MEMS flow sensor is designed to meet this need for an ultra-small sensor that can detect minute airflow with high sensitivity.

Overview of New Product
This cyclone-type MEMS flow sensor features Omron's unique Dust Segregation System (DSS), which enables it to detect minute flow rates with high sensitivity, even in dusty environments. This makes it ideal for flow rate control in air conditioners in homes and offices.

By using the world's smallest class of MEMS flow sensor element, Omron has succeeded in reducing the new sensor's footprint by 50% compared with previous models, allowing it to be easily built into increasingly smaller consumer products and measuring devices.

In addition, direct mounting to PCBs helps to lower total costs by preventing wiring errors and reducing labor requirements.

Moreover, in contrast with the uni-directional flow sensing of earlier models, the D6F-P offers bi-directional flow sensing for use in applications such as sensing air conditioner intake and exhaust, or human breathing.

Features
 

  • Omron's unique cyclonic Dust Segregation System (DSS) provides a high level of reliability by separating dust particles from air to reduce their effect on the sensor chip.

     

  • Compact (50% smaller footprint than the D6F-01A1).

     

  • In addition to PCB-mountable models, connector models are also available.

     

  • Suitable for bi-directional flow sensing.

Other Applications: Measuring devices, medical devices, and semiconductor equipment.

Price: Open price.

Sales Target: Approx. 10 billion yen in FY2008 for D6F Series
