Block diagram SM565X

The SM565X Series of OEM pressure transducers are a traditional fully calibrated, temperature compensated pressure devices in Dual-In-Line packages for printed circuit board mounting. These transducers offer improved performance as well as the option for either constant current or constant voltage excitation.

The sensors are not recommended for new designs. As an alternative check out the fully calibrated and amplified AMS 5812.

The SM565X Series pressure transducers are constructed by attaching a highly stable piezoresistive pressure sensor chip to a ceramic substrate. Thick film resistors on the ceramic are laser trimmed during manufacturing to provide zero offset calibration, temperature compensation for zero offset and temperature compensation for sensitivity.
