NTB-201A
A revolutionary concept of measurement has emerged
Signals from a sensor are usually digitized through an amplifier and A/D converter via a bridge box, and the digital data is processed on a computer or a dedicated system. NTB-100A Series network terminal boxes revolutionize this process signals from a sensor are immediately digitized and fed to a computer for data processing.These NTBs not only streamline signal processing, but also contributes to eliminating extra cable thereby reducing cost of labor and installation.By placing an NTB near a sensor, only a single communication cable is required to build a wide area network (a total distance of 1 km), which is also useful because the digital transmission is hardly affected by noise. A single unit can measure 4 channels, and up to 8 units can be connected, for measurement of a maximum of 32 channels is possible.The NTB, which directly connects various sensors including strain gages, facilitates digital measurement in the field such as construction or building site, or for indoor experiments and researches.Handy logger SME-100A allows a wider range ofmeasurement with its.
Features
- The wide area, decentralized arrangement will be useful for the infrastructure of building and civil engineering.
- Network output is compliant to CAN, requiring a single wire to build the network.
- Measurement can be started immediately when the instrument is connected to a computer.
- Various ways of interlocking and connection are provided, broadening system applications.
- Compact, lightweight and affordable, allowing a small-sized system to be built on site easily.
- Digitizing data adjacent to the sensor allows noise resistant digital data to be transmitted.
