Stiegele Datensysteme GmbH has developed a new object for displaying measurement data in sensor grids. The instrument visualizes the measurement readings from a rectangularly arranged sensor matrix (e.g. temperatures, pressure, distentions) and displays the gradual difference of the measured values in coloured gradients. This allows the quick visual identification of extreme values at individual sensors in the grid.

The versatile display element has been completely reprogrammed and can be adjusted to meet your specific requirements:

• Bilinearly interpolated representation;
• Schematic representation of the measured values as colour codes (without gradient);
• Display of MIN/MAX values;
• Transforming the display area:
  • Rotation,
  • Scaling in x and y direction,
  • Shift,
  • Transparency setting;
• Depositing of photos or technical drawings with the measured data interpolation being represented on the unit under test.

Additionally, more sensors can be mounted on the test object. In this way, you can increase measurement accuracy at especially interesting points. 

Possible applications for measuring are:

• Temperature distribution at the radiator grille (automotive),
• Stress-strain state of turbine blades,
• Pressure distribution over airfoils,
• Representation of the results of acoustic cameras.
