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 read instruction “Notes” before using the sensor.
Fujikura reserves the right to change specifications without notice.
Please keep the sensors sealed using static shielding bags on storage.The pins of the sensor are plated by Ag.
If the sensors expose to an atmosphere, the pins will be black by sulfuration.
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.
If you have any questions regarding technical issues or specifications, please contact us.
