SPECIFICATION NOTES

Note 1:

Full-Scale Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure.

Note 2:

Maximum pressure above which causes permanent sensor failure.

Note 3:

Sensitivity is ratiometric to supply voltage.

Note 4:

Performance specs are shown at reference conditions. Specifications apply for absolute pressure devices with pressure applied

to Port A. For gage devices, pressure is applied to Port B and Port A is left open for ambient. For differential pressures, Port B

is the high-pressure port. All differential devices feature dual pressure ports and can be used as gage or differential sensors.

For absolute devices, Port B is inactive.

Note 5:

Offset calibration is at the lowest pressure for each given device.

Note 6:

Linearity refers to the best straight line fit as measured for offset, full scale and ½ full-scale pressure.

Note 7:

Temperature errors are the maximum shift over 0 °C to 70 °C [32 °F to 158 °F], relative to the 25 °C [77 °F] reading.

Note 8:

Maximum difference in output at any pressure within the operating pressure range and the temperature within 0 °C to 70 °C

[32 °F to 158 °F] after:

a) 100 temperature cycles, 0 °C to 70 °C [32 °F to 158 °F]

b) 1.0 million pressure cycles, 0 psi to Full-Scale Span.

Note 9:

Response time for a 0 psi to Full-Scale Span pressure step change, 10 % to 90 % rise time.
