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

1220. Please contact the factory for additional information.
