Many explanation related to differential output voltage, instrumentation amplifier, precision, microcomputer, application, sensor, applications, amplifier interface, and pressure sensor are described in this a. Here are grabbed from this a:

The most popular silicon pressure sensors are piezoresistive bridges that produce a differential output voltage in response to pressure applied to a thin silicon diaphragm. Output voltage for these sensors is generally 25 to 50 mV full scale. Interface to microcomputers, therefore, generally involves gaining up the relatively small output voltage, performing a differential to single ended conversion, and scaling the analog signal into a range appropriate for analog to digital conversion. Alternately, the analog pressure signal can be converted to a frequency modulated 5 V waveform or 4-20 mA current loop, either of which is relatively immune to noise on long interconnect lines. A variety of circuit techniques that address interface design are presented. Sensing amplifiers, analog to digital conversion, frequency modulation and 4-20 mA current loops are considered

Additionally, this a contains more things like the instrumentation amplifier, the frequency output, temperature compensation, pressure sensors, circuits, instrumentation amplifier interfaces, instrumentation amplifiers, and the output voltage.
