Smart Dynamic Strain Recorder DC-204R / DC-204Ra
200-kHz high-speed sampling possible in 1-channel mode — connect 8 units at the same time for simultaneous sampling of up to 32 channels.
The DC-204Ra has analog output (±5 V) function for external recorder or automotive ECU.START/STOP button on front allows start of measurement by trigger setting, external trigger, control by external start/stop signal, etc.
- Features
- 4-channel configuration with miniature size like postcard
- 200 kHz sampling (at the fastest in 1-channel mode)
- Simultaneous 50 kHz sampling for 4 channels
- Capable of measuring a large strain of up to 80000 x 10-6 strain (with 0.5 V excitation)
- Data recording in compact flash card of 2 Gbyte 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
