DESCRIPTION
The Models 26 and 27 are high performance, temperature
compensated, piezoresistive silicon pressure sensors packaged in
a bottom tube TO-8 configuration. They provide 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 in the Model 27 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.
