Notes:

  1. Performance with offset, thermal accuracy of offset, and thermal accuracy of FSO compensation resistors.
  2. FSO with 1.5mA input excitation.
  3. Best fit straight line.
  4. 32°F to 158°F (0°C to 70°C) with reference to 77°F (25°C).
  5. 32°F to 158°F (0°C to 70°C), by design.
  6. Normalized offset/bridge voltage —100 hrs, typical value, not tested in production.
  7. All values measured at 77°F (25°C) and at 1.5 mA, unless otherwise noted.
  8. Reduced performance outside compensation range.
  9. Backside differential tube is nickel or Kovar.
  10. Top side pressure.
  11. Typical specifications are for reference only; absolute values may vary.
  12. For NPH-8, 2.5 kPa gauge (G) and differential (D) sensor, the input impedance is 3400 +/-30%
