Siargo announces low power MEMS fuel cell sensors

Aug. 17, 2006 – Siargo Ltd. of Santa Clara, Calif., announced the release of its low power MEMS sensors for fuel cell systems, including a gas mass flow sensor for solid oxide fuel cells and a methanol concentration sensor for direct methanol fuel cells.

The flow sensor measures the temperature redistribution of the sensor surface which depends on the media’s mass as well as the media’s flow speed. The company says its sensors are well suited to the application because they consume less power while offering good accuracy and response time.

The methanol concentration sensor measures a full range of methanol’s concentration in water from 0 percent to 100 percent with real-time, in-line measurement capability. The typical maximum power consumed is 15mW.

The company is now offering single or multi-channel packaged evaluation sensor units that fuel cell system customers can integrate into their products.
