Specification Notes:
1:
Reference Conditions: Supply Current = 1.0 mA, T
A=25°C, Common-mode Line Pressure = 0 psig, Pressure Applied to P1, unless otherwise noted.
2:
Accuracy is the sum of Hysterisis and Linearity. Hysterisis is the maximum output difference at any point within the operating pressure range for increasing and decreasing pressure.
Linearity refers to the best straight line fit as measured for the offset, full-scale and 1/2 full-scale pressure at 25°C.
3:
This is the maximum temperature shift for span when measured between 0°C and 50°C relative to the 25°C reading. Typical temperature coefficients for span and resistance are
-2200 ppm/°C and +2200 ppm/°C respectively.
4:
This is the maximum temperature shift for offset when measured between 0°C and 50°C relative to the 25°C reading.
5:
Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure.
6:
Maximum difference in output at any pressure with the operating pressure range and temperature within
0°C to 50°C after:
a)
100 temperature cycles, 0°C to 50°C
b)
1.0 million pressure cycles, 0 psi to full-scale span
7:
Response time for a 0 psi to full-scale span pressure step change. 10% to 90% rise time
8:
Temp effect on span and offset are guaranteed by design. Therefore these parameters are not 100% tested.
9:
The SCC100D devices can only be used in a forward gauge mode. Application of more than 30 psig to the back side of any of the SCC Series devices can result in device failure.
