DESCRIPTION

The Model 1240 is a high performance temperature

compensated, piezoresistive silicon pressure sensor packaged in

a dual-in-line configuration and intended for cost sensitive

applications where excellent performance and long-term

stability are required.

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, for interchangeability of 1%.

Gage and Differential pressure ranges from 0-15 PSI to

0-100 PSI are available. Absolute pressure ranges of 0-15 PSIA

and 0-30 PSIA are available. Multiple lead and tube

configurations are also available for customizing the package for

specific applications.

Please refer to the low pressure section for information on

products with operating pressures less than 0-2 PSI. For a

compensated sensor using a gain set resistor as opposed to a

current set resistor, please refer to the Model 1230.

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.
