Strain Gauge logging with DA99
Posted: Thu Jun 14, 2012 2:59 pm
The DA99 has 8 differential inputs.
The units are supplied with fixed gain of 1 (range 0-5 volt) but gains up to 100 (0-50mV or +/-50mV) are possible with a resistor change.
However this is not normally enough for direct connection to a strain gauge. We normally advise using a dedicated strain guage amp with a 0-5 volt output feeding into the unity gain differential amp.
