Specification notes:
1.
Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure.
2.
Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and decreasing
pressure. Linearity is the maximum deviation of measure output at constant temperature (25°C) from "Best Straight Line"
determined by three points, offset, full scale pressure and half full scale pressure.
3.
Maximum difference in output at any pressure with the operating pressure range and temperature within 0°C to +70°C after:
a) 100 temperature cycles, 0°C to +70°C
b) 1.0 million pressure cycles, 0 psi to full scale span
4.
Slope of the best straight line from 0°C and 70°C. For operation outside this temperature, contact Sensortechnics for more
specific applications information.
5.
Response time for a 0 to full-scale span pressure step change.
6.
Long term stability over a one year period .
7.
This parameter is not 100 % tested. It is guaranteed by process design and tested on a sample basis only.
8.
If the proof pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die may fracture.
Note: The proof pressure for the forward gage of all devices in the D4-package is the specified value or 100 psi, whatever is less.
9.
The zero pressure offset is 0 mV Min, 20 mV Typ and 35 mV Max for part nos. RXU...G2 and RXU...D4.
