WARNING:
Due to the delicate nature of these very sensitive devices, some special handling is required. Parts
are sensitive to shock and vibration and must be handled with care. Dropping on any hard surface
(bench top etc.) can destroy the device. Note 25 mbar overpressure!
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 +50°C after:
a) 100 temperature cycles, 0°C to +50°C
b) 1.0 million pressure cycles, 0 psi to full scale span
4. Slope of the best straight line from 0°C and 50°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 max. burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die may fracture.
