益友科技 HPSAC3000，HPSD3000 压力传感芯片

    Pressure transducer model HPSAC 3000 is a
temperature compensated pressure sensing
device with zero calibrated output.

    High performance and accuracy enables use of
this transducer in many applications, and with
its compact and handy design is very suitable for
end users. The HPSAC 3000 pressure transducers
are constructed on 1 mm thick ceramic substrate
with one or two pressure tubes. Thick film resistors printed on substrate are individually laser
trimmed to provide temperature compensation and zero calibration. An additional resistor
is trimmed according to individual transducer
span to provide easy transducer amplification
with external differential amplifier. Pressure media
compatible with this transducer family is dry air
or non-corrosive gases and liquids.

    The model HPSAC 3000 is designed for constant
current excitation. Whole family includes pressure
ranges from 10 mbar up to 7 bar.
