The DRA-30A is a multi-channel digital strainmeter intended for on-line measurement with a PC. The supplied software DRA-730A enables the instrument to be used as a digital dynamic strainmeter or a multi-channel simultaneous sampling data logger. As all channels have one-touch input/output connecter receptacles and bridge boxes, strain gauges and strain gauge type transducers can be easily connected. Measurement of voltage is possible in addition to strain measurement. 

Features: 
  • Either dynamic or static measurement possible (cannot be used together at the same time) 
  • Quarter bridge 3-wire, half bridge, full bridge and voltage selectable for each channel 
  • One-touch connecter receptacle provided for each channel in addition to conventional terminal 
  • Each channel incorporates A/D converter for simultaneous measurement and record of digital values 
  • Data memory of 112k words (30000 scans for static measurement) provided for each channel 
  • Easy on-line measurement with a PC using built-in GP-IB and USB1.1 interface 
  • Strain input is isolated for each channel ?High input impedance 
  • Operates on either AC90~250V or DC10~30V 
  • Data recording software DRA-730A supplied
