The SXL series of pressure sensors provides the lowest cost components
for measuring very low pressures. These low pressure range devices were
specifically designed to accurately measure differential and gage pressures
of 1 inch to ten inches of H
2
O.
They are meant for use with non-corrosive and non-ionic media, such as
air, dry gases, and the like.
These differential devices allow application of pressure to either side of the
diaphragm and can be used for gage or differential pressure measurements.

SPECIFICATION NOTES
Reference conditions: supply voltage Vs = 5 Vdc, Ta = 25 °C [77 °F]. Common-mode line pressure = 0 psig.
Pressure applied to P2.
Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure.
Slope of the best straight line from 0 °C to 50 ° C [32 °F to 122 °F]. For operation outside this temperature, contact
factory for more specific application information.
This parameter is not 100% tested. It is guaranteed by process design and tested on a sample basis only.
See definition of terms. Hysteresis is the maximum output difference at any point within the operating pressure
range for increasing and decreasing pressure
Long-term stability over a one year period.
Response time for a 0 PSI to full-scan span pressure step change. 10 % to 90 % rise time.
Maximum difference in output at any pressure with the operating pressure range and temperature within 0 °C to
50 °C [32 °F to 122 °F] after
a. 100 temperature cycles, 0 °C to 50 ° C [32 °F to 122 °F]
b. 1.5 million pressure cycles, 0 PSI to full-scale span.
If the maximum burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure
sensing die may fracture.
