DESCRIPTION
The Model 17 is a high performance, te mperature compensated,
piezoresistive silicon pressure sensor packaged in TO-8
configura tions. It pr ovides e x celle nt performance and long -term
stability over wide temperatures.
Gage and absolute pressure ranges from 0-15 PSI to 0-250
PSI are av a il able . In t eg r al te m p er at u re c o m p ensati o n is
provided over a ra ng e of -20°C to +85°C using laser-t ri mmed
resist o rs. An addi t ion al lase r-trimmed re sistor is incl u ded to
normalize pressure sensitivity variations by pr ogramming the
gain of an ext ernal differential amplifier. This provides
sensitivity interchangeability of ±1%.
Please refer to the low pressure section for information on
products with operating pressures less than 0-2 PSI. For an
uncompensated sensor (Model 15) please contact the fa ctory for
addit iona l infor mati on.

June 2001
PERFORMANCE SPECIFICATIONS
Supply Current: 1.5mA
Ambient Temperature: 25°C (Unless otherwise specified)
Notes
1. Output span of unamplified sensor.
2. Best Fit Straight Line.
3. For Model 17, compensation resistors are an integral part of the sensor
package; no additional external resistors are required. Pins 11 and 12
must be kept open. Model 17 is interchangeable only when used with a
gain stage.
4. Temperature range: -20°C 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.
8. Prevents increase of TC-Span due to output loading.
9. 3X or 500 psi maximum, whichever is less. 20 psi for 2 psi and 5 psi
versions.
10. Wetted materials are glass, ceramic, silicon, RTV, nickel, and gold.
11. Normalized offset bridge voltage: 7 days.
12. 1 year.
13. Between case and sensing element.
