DESCRIPTIONS

Model 671 incorporates MEMS technology and custom Application Specific Integrated Circuit (ASIC) technology in the design. It is specifically designed for tough automotive application.

Based on the piezo resistive principle two pressure sensor elements transform two system pressures into electrical output signals proportionally to the pressure.

Model 671 is designed to perform in the underhood harsh environment such as temperature extremes, vibration, thermal and mechanical shock, and corrosive chemical.
