PRODUCT OVERVIEW

Rotadata's Optical Pyrometry Systems provide a means of obtaining surface radiance temperature data from within aero-engines and power gas turbines. Our actuated systems are capable of scanning a range of blade heights or platform positions with each data sample stamped with radial and axial positional information. We have developed a range of different systems suitable for various application areas and environments. Minimum insertion systems are used where gas temperatures are high, short probes with fast scanning for less harsh aero-engine conditions and, for larger scan areas such as power turbines, longer probes can be traversed down the blade surface or rotated to scan platform surfaces.

Optical Pyrometry provides a non-invasive technique for the measurement of turbine surface temperatures. The system operates by viewing the infrared radiation emitted by the surface and converting this, via a photo-detector, to an electical signal that can be measured. When fitted with a suitable positioning system, the area viewed by the pyrometer can be varied and when this is used to observe rotating parts, a 2-dimensional map of the surface is produced.

In engine health monitoring applications, the surface temperature gives an indication of the condition of the blade, helping to identify the potential onset of temperature-related problems including fatigue, cracking and creep. When used during blade development, the pyrometer system provides measurements for design validation.

We maintain an active development program in all the areas of the technology required in our solution and continue to enhance system performance and measurement.
