How can the voltage signal from the pressure sensor be converted into the pressure value displayed? Is there a conversion formula? A/D conversion looks wrong, is it through programming?
Most of them are simple linear relationships, and it's good to know the scale coefficients.
Have you calibrated the pressure sensor? Or when buying, there will be a report that shows the electrical signal and the actual pressure signal corresponding
Where is the conversion? There is a linear relationship between the electrical signals produced by the pressure transmitter and its measured pressure range.For example, the transmitter outputs a voltage signal of 0-10V, and the measuring range is 0-1Mpa. The pressure change of 0-1Mpa corresponds to the voltage signal of 0-10V. 0V corresponds to 0Mpa, and 10V corresponds to 10Mpa.There is also a transmitter that outputs 4-20mA current signals, as well. Corresponding calculation can be.
