DAT DR 1G / USB – USB 22 BIT ANALOG / DIGITAL CONVERTER FOR LOAD CELLS AND STRAIN GAUGES

DAT instruments, dataloggers for: Jet grouting - Grouting - Cement injection - TAM grouting - Drilling - MWD - CFA - Deep mixing - Soil mixing - Vibroflotation - Diaphragm walls - Lugeon test - Mineral investigation

 

DAT DR 1G is an amplifier with a 22 bit analog to digital converter specific for load cells, strain gauges and sensors with Wheatstone bridge with mV/V output. It does not need external power supply. Input sockets let quickly connect the sensor. USB port let transfer acquired data directly to PC, without any additional adaptor.
