Hi,
pressure sensor 0 to 1barg, input supply 24V and output signal 0 to 10VDc. external 24v power supply connect to sensor and output wire from sensor connect to NI6001 AI1 port.
Base on the pressure sensor I select, I will only able to get positive data which from 0V to 10V range. but when the pressure sensor experience some negative pressure. why i still able to collect negative value from NI ? connection wire error? any expect can advise ?
