Specification Notes (Cont’d)

note

3: total accuracy iS tHe combineD error from offSet anD Span calibration, linearity, preSSure HyStereSiS anD temperature effectS.

note

4: tHe SenSor iS calibrateD witH a common moDe preSSure of 1 bar abSolute. Due to tHe maSS flow baSeD meaSuring principle, variationS in abS-

olute common moDe preSSure neeD to be compenSateD accorDing to tHe following formula

note

5: tHe max. common moDe preSSure iS 30 pSi

note

6: figure baSeD on accelerateD lifetime teSt correSponDing to 1 year of life.

note 7: tHe Digital output Signal iS a SigneD, two’S complement integer. negative preSSureS will reSult in a negative output.

note 8: pleaSe contact all SenSorS corporation for low power optionS.

note 9: non-linearity referS to a terminal baSeD fSl (fitting StraigHt line) going tHrougH tHe actual zero preSSure reaDing.

note 10: for example witH a fpSS500... SenSor meaSuring co

2 gaS, at full-Scale output tHe actual preSSure will be 2.00 inH2o x 0.56 = 1.12 inH2o.

note 11: for correct operation of fpS 3v DeviceS, tHe Device Driving tHe Spi buS muSt Have a minimum Drive capability of ± 2 mA.
