Measure more than 3 strain gauge half bridge

Question: I'm looking for a DAQ to record more than 3 strain gauge half bridge. Is it possible to do it with your system, and what will be the recording frequency for each gauge, and the resolution?

Answer: To measure 5 strain gauge half or quarter bridge, you can use the following configuration. You will need the sensor bridge application adaptor together with the EMANT300 USB DAQ or the EMANT380 Bluetooth DAQ. Usually the bridge is connected to analog input pairs (AIN0-AIN1, AIN2-AIN3, AIN4-AIN5). But in this configuration, AIN0 is common leading to AIN0-AIN1, AIN0-AIN2, AIN0-AIN3 ...

5 strain quarter bridges

The sampling rate at best is about 30Hz/(3*5) = 2Hz. Please see the following post for the reason.
