Why is the output voltage of the pressure sensor 0.5~4.5V instead of the 0~5V voltage?
Any sensor has to enter the linear to exit linear process, the need to output 0--5v can be caused by the circuit.
There are also 0-5V, and this is the question of type selection.The type and size of the sensor output signal may be required for production
General 0.5~4.5V sensor supply are only 5V, when cannot output 5V, in addition, there is a zero base 0.5V, when the pressure sensor input can easily infer whether there is fault, such as fault, zero output is often not the 0.5V.If the zero is set to 0V, it is not good to judge, and the fault may also show 0V.
