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.
