Specification Notes
1) ALL PARAMETERS ARE MEASURED AT 5.0 VOLT EXCITATION, FOR THE NOMINAL FULL SCALE PRESSURE AND ROOM TEMPERATURE UNLESS OTHERWISE SPECIFIED .
PRESSURE MEASUREMENTS ARE WITH POSITIVE PRESSURE APPLIED TO P ORT B. ABSOLUTE DEVICES ARE WITH PRESSURE APPLIED TO PORT A.
2) SHIFT IS RELATIVE TO 25°C.
4) MEASURED AT ONE-HALF FULL SCALE RATED PRESSURE USING BEST STRAIGHT LINE CURVE FIT FOR THE SPAN INDICATED.
5) THE VOLTAGE ADDED TO THE OFFSET VOLTAGE AT FULL SCALE PRESSURE. NOMINALLY THE OUTPUT VOLTAGE RANGE IS 0.25 TO 4.75 VOLTS FOR MINUS TO
PLUS FULL SCALE PRESSURE .
6) PARAMETER IS COMPUTED AS MAXIMUM FOR DESIGN REFERENCE AND IS NOT TESTED.
7) MAXIMUM DIFERENCE IN OUTPUT AT ANY PRESSURE WITHIN THE OPERATING PRESSURE RANGE AND COMPENSATED TEMPERATURE RANGE AFTER: A) 1000
TEMPERATURE CYCLES AND B) 1.0 MILLION PRESSURE CYCLES .
8) RESPONSE TIME FOR A ZERO TO FULL SCALE PRESSURE STEP CHANGE, 10% TO 90% RISE TIME.
