P1= 34.66 kPa.abs
P2= 67.98 kPa.abs
P3= 101.3 kPa.abs
P4= 168.0 kPa.abs
T1= 0 deg.C
T2= 25 deg.C
T3= 50 deg.C
Offset voltage (mV)
Voff = V(P3,T) at 101.3kPa.abs
Output voltage at full scale (mV)
V(P1,T) at 34.66kPa.abs
V(P4,T) at 168.0kPa.abs
Output span voltage (mV)
SV = V(P4,T) - V(P1,T)
SV(0) = V(P4,T1) - V(P1,T1)
SV(25) = V(P4,T2) - V(P1,T2)
SV(50) = V(P4,T3) - V(P1,T3)
Temperature sensitivity of offset voltage (%FS)
TSO = {LARGER ONE} / SV(25) x 100
LARGER ONE = larger absolute value which of {V(P3,T1)-V(P3,T2)} and {V(P3,T3)-V(P3,T2)}
Temperature coefficient of output span voltage (%FS)
TCS = {max[SV(0),SV(25),SV(50)] - min[SV(0),SV(25),SV(50)] } / SV(25) x 100
Linearity (%FS)
NL = {V(P2,T2) - [V(P1,T2)+V(P3,T2)]/2 } / SV(25) x 100
Pressure hysteresis (%FS)
Phys = {V’(P3,T2) - V(P3,T2) } / SV(25) x 100
V’(P3,T2) : Output voltage against P1 after stressing by P3 pressure.
