(1)
Total Error is the sum of worst case linearity, repeatability, hysteresis, thermal effects, and calibration errors over the operating
temperature range. Accuracy is only achieved after applying the correction coefficients and algorithm as shown in section 3.2. (FS =
Full Scale) For total error calculations of differential units, "Full Scale" is the pressure difference between the minimum and maximum
pressures. For example, full scale for a 1 psid PPT is 2 psi (-1 to +1 psi).
(2)
After applying the correction coefficients stored in EEPROM, the resultant pressure reading is expressed in PSI (pounds per square
inch).
(3)
Not including any mounting hardware. Dimensions in section 2.3 do not include Humiseal 1A33 conformal coating which is typically
applied to the PWB assembly at a thickness of 1-3 mils.
(4)
Operation with a digital interface > 3.3V can damage the IPT and cause shifts in the ADC output.
(5)
IPT electronics require protection from humidity.
(6)
IPT requires shielding from EMI.
