Smart Dynamic Strain Recorder DC-204R/DC-204Ra

DC-204R/DC-204RaThe DC-204R and DC-204Ra are compact flash storage type dynamic strain recorder featuring ultra-small size.They can also measure DC voltage and thermocouple by using optional cable and adaptor. The DC-204Ra has analog output (±5V) function for external recorder or automotive ECU. The frequency response is 10kHz and sampling speed is 200kHz at the fastest. The standard software DC-7204 can control 8 units of DC-204R/DC-204Ra (32 channels) at the maximum.


Features

  • 4-channel configuration with miniature size like postcard
  • 200kHz sampling (at the fastest in 1-channel mode)
  • Simultaneous 50kHz sampling for 4 channels
  • Capable of measuring a large strain of up to 80000×10-6 strain (with 0.5V excitation)
  • Data recording in compact flash card of 2Gbyte capacity
  • Automatic data protection against power failure. When the power is droped unexpectedly, stops measurement and stores data before turning off the power.
  • Data format conforms to DADiSP format
  • External start/stop and external trigger
  • Sensor open-circuit check function
  • USB Interface installed and standard control software supplied
