Barometer Signal Conditioner
The schematic diagram below show a complete barometric pressure signal conditioner that operates from a single 1.5V battery. We can get the best accuracy and stability if we use bonded strain gauge and capacitive-based transducer, but they are expensive. This design introduce a new type of semiconductor transducer that achieves 0.01″ Hg (inches of mercury) uncertainty over time and temperature. […]
