Inside the technical note the reader can find explanation related to circuit, absolute pressure sensors, pressure, offset voltage, and pressure sensors. The technical note contains info related to calibration, offset, output, and the offset voltage.
Many discussion like offset error, barometric, gage sensors, equation, and calibration process are presented in this technical note. Here are taken from the technical note:
Understanding Absolute Pressure Sensors INTRODUCTION Most people are typically accustomed to dealing in gage pressure, that is, pressure relative to the normal atmospheric pressure which surrounds us. FIGURE2 Sensor Amplifier Circuit with Calibration Adjustments 2 Honeywell • Sensing and Control Technical Note Understanding Absolute Pressure Sensors (This is equal to14.60 psi, as 755 mmHg x 0.019337 psi/mmHg=14.60 psi.) Mathematically, it can easily be shown that using these two refer ence pressure points (barometric pressure and a gage reference), one can properly adjust for offset and span. Technical Note CONCLUSION Although absolute pressure sensors are perhaps not as well understood or easily calibrated as gage pressure devices, by using barometric pressure as a reference in conjunction with any other reference point, gage or absolute, absolute pressure devices can be accurately calibrated.
