Our Company


DunAn Sensing LLC is a Silicon Valley, Calif., based company founded in 2014.  Our leadership and many members of our engineering staffs have a long track record in the MEMS pressure sensor industry.  We offer high-performance OEM pressure sensors, transducers, and transmitters, which are hermetically sealed and compatible with harsh media. 

Our pressure sensor products do not require isolation from the media that are being measured, unlike traditional-type packages that require welded metal membranes and cavities to be filled with oil.  The simpler construction of our pressure sensing solution, which is based on our patent-pending MEMS packaging technology and eliminates the above-mentioned welding and oil fill, results in a higher performance, a higher reliability, and the possibility to miniaturize without loss in accuracy. 

Our low-cost OEM pressure sensor can be manufactured in standard packages and can also be customized to fit any specific application for which we recommend you to work with one of our Custom Engineering specialists.
