DESCRIPTION
The Models 22 and 23 are temperature compensated,
piezoresistive silicon pressure sensors packaged in TO-8
configurations. They provide 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 in the Model 23
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 Models 22 and 23
has a double bossed design that produces a high sensor output
of 100 mV (typical) at 1 PSI.
The Models 12 and 13 are 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.
