Digital dynamic strainmeter DRA-162B
This carrier wave type dynamic strainmeter is designed for on-line measurement using a personal computer.
Input waveforms are continuously digitized, recorded in the internal memory, and transferred to a PC.
Since dynamic phenomena can be captured numerically, data analysis using a PC is easily possible.
Equipped with a data memory of 256k words/channel, data trigger start and pre-trigger recording are also possible.
It also provides analog outputs similar to those of ordinary dynamic strainmeters.
All operations are performed from a PC via a LAN interface.
In addition to strain gage and strain gage transducers, voltage measurement is also available.
- Features
- Built-in 16-bit A/D converter for each channel, waveform recording by digital value
- Built-in 256k words/channel data memory (for 16 channels)
- Remote sensing of bridge voltage minimizes sensitivity degradation during cable extension (up to 100 m)
- Each setting can be PC-controlled
- Data backup possible on the main unit of the instrument
- Bridge voltage switching (0.5 VAC, 2 VAC) can be set independently for each channel
- Built-in check functions (sensitivity, input open, over, insulation)
- Capable of transferring recorded binary data over a LAN at a rate of approx. 500 kwords/second
- TEDS sensor data readable
- Card-type internal configuration for easy maintenance
- Synchronous measurement is possible with up to 16 units (256 channels) connected
- DRA-7162 acquisition software is included as standard equipment.
