DESCRIPTION
The Model 43 is a temperature compensated, piezoresistive
silicon pressure sensor packaged in TO-8 configurations. It
provides excellent performance and long-term stability.
Gage and absolute 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 40) is also available. For sensors
in a dual-in-line package please refer to the Models 1210 and
FEATURES
1220. Please contact the factory for additional information.

Notes
1. Best Fit Straight Line. For 2 psi output span is 30-60 mV and TC zero
temperature error is ±1.25%.
2. Temperature range 0-50°C in reference to 25°C.
3. Guarantees input/output ratiometricity.
4. For a zero-to-full scale pressure step change.
5. 10 Hz to 1 kHz.
