Notes:
1. Reference Conditions: Supply voltage, Vs = 5.0 Vdc, T
A
= 0 °C to 70 °C [32 °F to 158 °F], common-mode line pressure =
0 psig, pressure applied to P1 unless otherwise noted.
2. If maximum pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing die may
fracture.
3. Sensitivity is the ratio of the output signal voltage change to the corresponding input pressure change. The sensitivity is
characterized by design and periodic production testing. This parameter in not 100 % tested in production.
4. This is the best straight line fit for operation between 0 °C to 70 °C [32 °F to 158 °F]. For operation outside this temperature,
contact Honeywell representative for more specific application information.
5. This parameter is not 100 % tested. It is guaranteed by process design and tested on a sample basis only. Temperature
coefficient of span for the 1.0 psi and 5.0 psi devices is -2550 ppm/°C to -2050 ppm/°C.
6. Slope of the best straight line fit for operation between 0 °C to 70 °C [32 °F to 158 °F]. For operation outside this temperature,
contact factory for more specific application information.
7. Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and decreasing
pressure.
8. Long-term stability over a one year period.
9. Response time for 0 psi to full scale span pressure step change.
10. Difference in output at any pressure with the operating pressure range and temperature within 0 °C to 70 °C [32 °F to 158 °F]
after 100 temperature cycles 0 °C to 70 °C [32 °F to 158 °F], 1.0 million pressure cycles 0 psi to full-scale span.
