DESCRIPTION
The Model 27 is a high performance, temperature compensated,
piezoresistive silicon pressure sensor packaged in a bottom tube
TO-8 configuration. It provides excellent performance and
long-term stability.
Gage 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. For an
uncompensated sensor (Model 25) please contact the factory for
additional information.
