Pressure(kPa) =Port1 pressure - Port2 pressure
P1= 0 kPa
P2= 1/2 x P3 (kPa)
P3= reted pressure (kPa)
T1= 0 deg.C
T2= 25 deg.C
T3= 50 deg.C
Offset voltage (mV)
Voff = V(P1,T)
Voff(0) = V(P1,T1)
Voff(25) = V(P1,T2)
Voff(50) = V(P1,T3)
Output voltage at full scale (mV)
Vfs = V(P3,T)
Vfs(0) = V(P3,T1)
Vfs(25) = V(P3,T2)
Vfs(50) = V(P3,T3)
Output span voltage (mV)
SV = Vfs - Voff
SV(0) = Vfs(0) - Voff(0)
SV(25) = Vfs(25) - Voff(25)
SV(50) = Vfs(50) - Voff(50)
Temperature sensitivity of offset voltage (%FS)
TSO = {LARGER ONE} / SV(25) x 100
LARGER ONE = larger absolute value which of {Voff(0) - Voff(25)} and {Voff(50) - Voff(25)}
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) - [Voff(25)+Vfs(25)]/2 } / SV(25) x 100
Pressure hysteresis (%FS)
Phys = {Voff’(25) - Voff(25) } / SV(25) x 100
Voff’(25) : Output voltage against P1 after stressing by P3 pressure.

Please set Zero-calibration function up your products. The offset voltage may be shifted some mechanical stress
such as mounting, installation and etc. over longtime using.
