Ther­mo­graphy for Quality Assur­ance

Today gas turbine power plants by the SIEMENS AG are more than ever complex high-tech products. They provide a continuous and reliable electrical power supply for industry and population worldwide. They do this using fossil fuels very efficient and therefore exceptionally friendly for our environment. To achieve this highest quality of every single component is absolutely imperative. Thus heavily stressed parts like the turbine blades are tested with the latest measurement techniques for example with infrared thermography.

During the production of the turbine blades for gas turbine power plants the Siemens AG uses ceramic coatings since higher entry temperatures to the turbine blades are reachable which increases efficiency. Thereby it is necessary to ensure the correct application of the coatings with-out any losses at the flow channels. Mr. Sczepurek together with his team takes the responsibility for the required test techniques and processes. Out of the range of non-destructive testing methods he chose infrared thermography as it allows for checking large turbine areas particularly fast and reliable at the same time.

Infrared camera
ImageIR® 8300

InfraTec supports this quality assurance by supplying high-performance and reliable infrared cam-eras from its own ImageIR® series manufactured in Dresden. The geometric resolution of 640 x 512 pixels being high for commercial, cooled thermal cameras provides together with a fast frame rate the necessary prerequisites to realize the test of every turbine reliably but also in eco-nomically justifiable time.

A fast motorized focussing as well as a data acquisition to the split milisecond and a camera control by a capable and cus-tomizable software of InfraTec also plays an important role. The flexible inter-face concept of the ImageIR® camera moreover allows for a seamless integration into the existing system environment. Additionally, the infrared cameras of the ImageIR® series can be combined with external excitation devices due to its precise trigger possibility. Thus, further parameters of turbine blades can be de-termined within the methodology of active heat flow thermography. Their analysis and practical ap-plication result in a further increase in efficiency for the customers of the gas turbine power plants of the SIEMENS AG.

InfraTec glossary modules

Modular Concept

Customised Configuration and Retrofitting

Due to their modular design, the cameras in the ImageIR® series can be adapted to user requirements and retrofitted or converted if measurement requirements change.

InfraTec glossary about motor focus

Motor Focus

Remote-controlled Focussing of the Thermal Image

Interchangeable standard lenses in the ImageIR® series can be equipped with a motor focus unit. This enables precise, remote-controlled and fast focussing via the operating software.

InfraTec thermography - Geometrical Resolution

Geomet­rical Resol­u­tion – Effi­cient Analysis of Complex Assem­blies

InfraTec's infrared cameras with cooled and uncooled detectors have native resolutions up to (2,560 × 2,048) IR pixels. Spatially high-resolution thermograms ensure that components and assemblies are imaged down to the smallest detail and thus defects can be reliably detected and precisely localised.

Trigger interface for ImageIR® and TarisIR® cameras

Trigger Interface

Interface for Incoming and Outgoing Control Signals
Trigger signals to or from the camera can be used to control and synchronise image data acquisition. Thermographic measurements can also be used to control processes.
