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.
Differential pressure ranges from 0-2 PSI to 0-250 PSI are
available. Integral temperature compensation is provided over a
range of 0-50°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. An
uncompensated sensor (Model 30) is also available. For sensors
in a dual-in-line package please refer to the Models 1210 and
1220. Please contact the factory for additional information.
