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.
