How many pressure sensors can be connected to a pressure sensor?
In general, there are at most 48, 48 sensors in the acquisition instrument cycle display, acquisition instrument can connect to the computer, with software, all channels can be real-time display and historical data curve analysis. Wiring, 3 wire voltage output pressure sensor, signal and power supply, the two wire current pressure sensor, the ground string through the acquisition instrument on it
Now commonly used patrol instrument (also known as acquisition instrument), whether it is the temperature or pressure, the common standard for the 8 road acquisition, followed by 16, 32, etc.. Since the pressure sensors need to be powered, there are too many points to consider the problem of external power supply.
This is difficult to say, there are specifications, to see how many design needs, there is no specific! More or less, generally 12 road, 24 Road, 48 road all!
