Notes
1. Output span of unamplified sensor using current set resistor.
9. 3X or 200 psi maximum, whichever is less.
2. Best Fit Straight Line.
10. Wetted materials are glass, ceramic, silicon, RTV, nickel, gold, and
aluminum.
11. Soldering of lead pins: 250°C for 5 seconds maximum.
3. Compensation resistors are an integral part of the sensor package; no
additional external resistors are required. Pins 7 and 8 must be kept
open.
12. Tube length: L=470 5 mil, S=300
3 mil, N=no tube.
4. Temperature range: -20 to +85°C in reference to 25°C.
5. Guarantees input/output ratiometricity.
6. For a zero-to-full scale pressure step change.
7. 10 Hz to 1 kHz.
13. Lead pins can either be in the same or the opposite direction as the
pressure tube. See Connections/Dimensions drawing for lead
configurations.
14. Normalized offset bridge voltage: 7 days.
15. 1 year.
8. Prevents increase of TC–Span due to output loading.
