DESCRIPTION
The Model 33 is a temperature compensated, piezoresistive
silicon pressure sensor packaged in TO-8 configurations. It
provides excellent performance and long-term stability.
Integral temperature compensation is provided over a range
of 0-50°C using a laser-trimmed ceramic compensation board.
An additional laser-trimmed resistor is included which can be
used to adjust the gain of an external differential amplifier and
provide sensitivity interchangeability of 1%.
The sensing element used in low pressure Model 33 has a
double bossed design that produces a high sensor output of
100 mV (typical) at 1 PSI.
The Model 33 is also available in ranges up to 0-250 PSI.
For sensors in a dual-in-line package please refer to the Models
1210 and 1220. For additional information regarding
uncompensated sensors, please contact the factory.

Notes
1. Output span of unamplified sensor.
5. For a zero-to-full scale pressure step change.
6. 10 Hz to 1 kHz.
7. Between case and sensing element.
8. Wetted materials are glass, ceramic, silicon, RTV, nickel, gold, and
aluminum.
2. For most models, compensation resistors are in an integral part of the
sensor package; no additional external resistors are required. Test pins
must be kept open.
3. Best Fit Straight Line.
4. Temperature range: 0-50°C in reference to 25°C.
