Setra Systems, Inc. was founded in an age of transducer innovation. Our founders, Dr. Y.T. Li and Dr. S.Y. Lee were professors of engineering at the Massachusetts Institute of Technology and co-developers of the variable capacitance transduction principle. Building on this heritage of innovation, Setra has designed and developed the most comprehensive product lines of sensing devices in the world. Setra has been innovating test & measurement sensor designs for over 50 years and has become a leader in the pressure transducer market.


    Since our founding, we have been proudly producing all of our transducers for sale in the United States at our 100,000 sq. ft. Boxborough, MA facility. Setra is an ISO 9001-2008 certified manufacturer with robust and mature processes at work to continually optimize team performance.
