DESCRIPTIONS
Model 621 incorporates MEMS technology and custom Application Specific Integrated Circuit (ASIC) technology in the design. It is specifically designed for tough automotive application.
The Temperature Manifold Air Pressure sensors in Model 621 provide tow separate outputs critical to air/fuel ratio optimization:
l One voltage output proportional to engine intake manifold pressure
l One resistance output proportional to manifold air temperature
Model 621 is designed to perform in the underhood harsh environment such as temperature extremes, vibration, thermal and mechanical shock, and corrosive chemical. Please contact us for special design to meet your requirements.
