DESCRIPTION
The Model 47 is a high performance, te mperature compensated,
piezoresistive silicon pressure sensor packaged in a differential
TO-8 configuration. It provi des excellent performance and
long-term stability.
Differe ntial pre ssure ranges from 0-15 PSI to 0-250 PSI ar e
avai l ab le. Integral temperature compensation is prov ided over a
range of - 20°C to +85°C using laser-trimme d resistors. An
additional laser-trimmed re sistor is included to normalize
pressur e sensitiv ity variations by pr ogramming the gain of an
ex te rn a l d iff e ren t ial am plifie r. Th is prov id es sen sit ivit y
inte rchangeability 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 35) please contact the factory 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 47, 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 47 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, gold, and
aluminum.
11. Normalized offset bridge voltage: 7 days.
12. 1 year.
13. Between case and sensing element.
