The DRA-162B is a carrier type dynamic strainmeter intended for on-line measurement with a PC. Input waveform is continuously digitized, stored in the internal memory, and transferred to a PC. As the dynamic phenomena are captured in digital form, data analysis with PC becomes easy. The data memory of 256k words/channel is provided, and data trigger start and data trigger recording are possible. Analog output like ordinary strainmeters can also be obtained. All operations are controlled from PC via LAN interface. In addition to strain gauges and strain gauge type transducers, voltage measurement can be made. 

Features: 
  • A 16-bit A/D converter is built-in for each channel Recording waveform in digital data 
  • Built-in data memory of 256k words/channel (for 16-channel model) 
  • Remote sensing of bridge excitation voltage Less sensitivity decrease with cable extension (max. 100m) 
  • Possible computer control for each setting 
  • Data back-up available by the strainmeter 
  • Selectable between AC 0.5V and 2V excitation individually for each channel 
  • Check function (sensitivity, input open, over and insulation) provided 
  • High-speed transfer of binary data by LAN Approx. 500k words/sec. 
  • TEDS compatible 
  • Card type internal composition for easy maintenance 
  • Connectable 16 units (256 channels) at the maximum for synchronous measurement 
  • Data reading software DRA-7162 supplied
