PCI Data Acquisition Boards from Measurement Computing Corporation with Dasylab software provide an impressive data acquisition solution to display results from multiple strain gauge installations
PCI Data Acquisition Boards from Measurement Computing Corporation (formerly ComputerBoards) with Dasylab software provide an impressive data acquisition solution to display results from multiple strain gauge installations.
Now you can use a PC to display the results from a multiple strain-gauge installation with a solution recommended by Adept Scientific.
Having worked with many customers to create some impressive precision instrumentation applications, Adept Scientific's Data Acquisition Team now suggest a solution for this notoriously demanding task With the effort and expertise required to use strain gauge transducers properly, it's essential that the electronics and software for measuring and displaying the signals are accurate, reliable, and versatile.
Engineers often want to measure and display high speed signals from accelerometers, alongside a large number of slow-changing signals from thermocouples and strain gauges, etc.
Not only do these have to be recorded simultaneously, but the equipment needs to be versatile enough for it to be continuously reconfigured as development goes on, and it's almost essential that the data is immediately available on a PC in a standard Windows application for subsequent use.
Signal conditioning hardware allows accelerometers, thermocouples, displacement transducers and strain gauges to all be connected to a multi-channel MMC PCI data acquisition board.
The signal conditioning hardware provides excitation, amplification and can auto-zero signals to remove static offsets.
Although there is a lot of good hardware around for capturing fast signals, the key is to sample as slowly as is consistent with getting good data and to focus the speed only on the areas of real interest.
With the MCC/Dasylab combination, Adept Scientific can provide what you need to do this.
Most importantly of all, the element of the system which needs the real 'tweaking', the signal conditioning, is separated to allow that to be done in isolation, and the PC interfacing is in the hands of low-cost, fit-and-forget hardware.
The MCC data acquisition boards offer auto-calibration, on-board references and many more useful features.
Dasylab is one of the most easy to use Windows data acquisition software applications.
It enables the signals to be measured, recorded and displayed in a straightforward but highly versatile way.
Designed for industrial research and scientific laboratories, its simplicity makes the application ideal for anyone with no PC programming experience - but even users who do have programming skills will benefit from the speed with which systems can be set up and subsequently developed.
It supports a wide range of data acquisition hardware from all leading manufacturers.
Dasylab includes a wide range of function blocks - analogue inputs and outputs, RS232 inputs and outputs, digital I/Os, user-definable triggers, function generators, virtual instruments and analysers, and mathematical, statistical and logical operations - as well as output modules to record events to file.
Function blocks can be combined in almost unlimited ways, within worksheets of any size, to allow real-time data analysis of even the most complex systems.
Users can zoom in on a specific event or data point, scroll back to study historical trends and monitor events as they happen.
And all this is very user friendly ? it's just selecting and connecting icons on a Windows screen.
For users needing even more functionality, an extended edition of Dasylab is available.
The additional modules include FFT/spectral analysis; data windowing; digital filter; regression; correlation; and an event-driven action module.
