DESCRIPTION

The SM5600 Series of OEM pressure sensors are fully calibrated, temperature compensated pressure transducers 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. Ultra-low pressure ranges are also available, resulting in the broadest selection of standard pressure ranges in the industry.

The SM5600 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. In the model SM5651, an additional resistor is trimmed to normalise the output of an external differential amplifier to provide span calibration when the transducer is driven by a constant current supply. In the model and SM5652, a constant voltage supply can be used and the normalised output span of each sensor can then be easily amplified. Various electrical pin and pressure port configurations are available for flexibility in matching this product to specific applications.

The model SM5651 is designed for constant current excitation. The model SM5652 is designed for constant voltage excitation.
