The DA-37A is a carrier wave type dynamic strainmeter with high frequency response of 10kHz. One unit is for one measurement channel, and two or more units can be installed in an exclusive case or rack to make a multi-channel system. By installing the units in the exclusive carrying case for computer control, control from a PC via LAN is possible such as settings of sensitivity and low pass filter, operation of balancing and calibration, and acquisition of setting and monitor values. 

Features: 
  • High frequency response of DC~10kHz 
  • Digital monitor of output voltage, with indication of maximum/minimum value and open/over 
  • Digital sensitivity setting method for easy and accurate setting 
  • Reduced sensitivity variation due to strain gauge resistance 
  • Electronic automatic balancing 
  • Isolation between input and output 
  • Automatic tracking capacity balancing 
  • Peak hold function privided 
  • Dual output 
  • Built-in low-pass filter 
  • Insulation resistance check function for strain gauge bridge 
  • External control possible for balancing and calibration signal output 
  • Dual power supply of AC and DC 
  • Possible control by PC (when installed in exclusive case)
