DESCRIPTION
The Model 17 is a high performance, temperature compensat-
ed, 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.

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 for span.
6. For a zero-to-full scale pressure step change.
