Multi-channel Dynamic Strainmeter DS-50A

DRC-3410The DS-50A is a multi-channnel dynamic strainmeter for on-line measurement with a personal computer. One set of DS-50A is composed of five measurement units, which covers 10 channels for each one unit (50 channels for one DS-50A). Strain unit and voltage unit are available. Number of these two units should be specified when ordering a DS-50A. Measurement is made using a standard software DS-750 supplied to the DS-50A or an optional Dynamic measurement software Visual LOG DS-7640 which is specially prepared for DS-50A. The system enables dynamic measurement of multi-points scattered in a wide area at low cost.


  • 1kHz sampling at the fastest when 1 set is used.
  • Simultaneous measurement of 20 sets (1,000 channels) is available at the maximum.(Using software DS-7640)
  • Bridge box is built in for each channel of strain unit.
  • The distance between each two DS-50A can be extended up to 100 meters using the exclusive cable.
