DESCRIPTION
The Model 17 is a high performance, temperature compensated,
piezoresistive silicon pressure sensor packaged in TO-8
configurations. It provides excellent performance and long-term
stability over wide temperatures.
Gage and absolute pressure ranges from 0-15 PSI to 0-250
PSI are available. Integral temperature compensation is
provided over a range of -20°C to +85°C using laser-trimmed
resistors. An additional laser-trimmed resistor is included to
normalize pressure sensitivity variations by programming the
gain of an external 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 factory for

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.
