GENERAL DESCRIPTION
The SCC series offer an extremely low
cost sensor element with a temperature
stable output when driven with a constant
current source. These integrated circuit
sen-sors were designed for extremely cost
sensitive applications where precise
accuracy over a wide temperature range
is not required. This series is intended for
use with non-corrosive, non-ionic working
fluids such as air and dry gases.
Absolute devices have an internal vacuum
reference and an output voltage proportio-
nal to applied pressure. The differential
devices allow application of pressure to
either side of the diaphragm and the devices
are thereby available to measure both dif-
ferential and/or gage pressures.
This product is packaged either in
SenSym´s standard low cost chip carrier
"button" package, a plastic ported "N"
package, a metal package or a dual inline
package (DIP). All packages are designed
for applications where the sensing element
is to be integral to the OEM equipment. The-
se packages can be O-ring sealed, epoxied,
and/or clamped onto a pressure fitting. A
closed bridge four-pin SIP configuration is

provided for electrical connection to the
button package. The TO can and the DIP
offer a 5-pin open bridge configuration.

Specification Notes:
1: Reference Conditions: Supply Current = 1.0 mA, TA=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.
