I have an experiment where a syringe is used to compress air. the compressed air is measured using a pressure sensor which converts to voltage on a multimeter. I need to transfer the volts to pascals. I know that the sensor voltage output is directly proportional to the pressure exerted on the sensor. We know the sensor sensitivity, the dc supply voltage, and the amplifier gain. Have been trying to figure it out for days!! any ideas as to where to start or get any web information that will help.
