Calibration bench for drill stem and oil sensors with Labwindows / CVI Measurement software screenshot

Hardware Technology

The system is composed of a PC computer which dialogs with oil sensors via serial bus and it is linked to a bench via GPIB bus.
The bench contains several modules :
  • Power supplies
  • Counter
  • Swithes Matix
  • Multimeter
  • Barometer
  • Pressure generator
  • Temperature generator

Software Technology

Operating software : MS Windows 2000
Measurement software : NI LabWindows/CVI
Analysis software : Visual Basic, MS ACCESS, ODBC, SQL
Report formats : MS EXCEL, PDF

How does it work ?

The measurement software controls the temperature and the pressure generated in simulated oil well. Sensors to calibrate, situated down into the oil well, send data to the measurement software. Theses data are stored in a database. At the end of the measurement campaign, recorded data available in the database are analyzed and graph reports are generated (PDF or excel reports).

What is LabVIEW?

LabVIEW LabVIEW is a development environment specialized in industrial and scientific applications. Its uniqueness is that it relies on the G language, created by National Instruments, which is fully graphical. It can create complex software, while facilitating the programming and thus reduce development time. Through its library of functions for data acquisition, instrumentation, analysis of mathematical measures, but also through the rapid creation of GUIs and coding simplified, the engineer has more time to focus on specific functions of the instrumentation communication and measurement analysis.

LabVIEW is particularly suitable for developing control, supervision, test and measurement systems.

What is LabWindows/CVI?


With LabWindows / CVI, you can develop:

  • software for Windows (exe) or UNIX Linux,
  • libraries (DLL, Active X,. NET),
  • instrument drivers,
  • on embedded targets,
  • on real-time target.

What is Measurement Studio

Measurement Studio pour Visual Studio C++, C# et Visual Basic These are libraries of graphical controls and functions for the rapid development of industrial or laboratory solutions containing .NET technology used directly in Visual Studio, to have power tools National Instruments software and instrumentation functions for C++ , C# or Visual Basic.
