App181 en blade-profile_measurement

  1. 1. A181_e2D / 3D Laser ScannerscanCONTROLProfile measurement of compressor blades under high temperature conditionsThe thermal geometric change under operating condi-tions needs to be measured on a new type of compositematerial for gas power plants.The compressor blade is heated up to 400°C. The struc-ture of the material has been selected so that the cur-vature produces the required shape of the blade. Thecompressor blade is also located in a holder. In this way,the blade is thermally and flow stressed. The scanCON-TROL2700-100 is positioned outside of this atmosphereand is aimed through a glass pane onto the blade, whilethe curvature is observed. The glass pane is located closeto the sensor and so does not influence the scanner.Requirements for the measuring system:- Measuring range approx. 50mm- Accuracy approx. 0.2mm in relation to arc- Resolution 0.05mm- Surface: optical mattAmbient conditions:- Sensor at room temperature- Target approx. 400°CSystem design:- Hot air flow channel- Holder for turbine blade- Glass pane – close to sensorBenefits for the customer:- Very large base distance of 300 – 600mm- No post-processing of the data- DLL interface for own programming- Relative measurement through protective glass withoutloss of accuracy is possibleMICRO-EPSILON A member of micro-epsilon groupKönigbacherstr. 15 Tel. +49 (0) 85 42/1 68-0 info@micro-epsilon.com Certified DIN EN ISO 9001 : 200094496 Ortenburg/Germany Fax +49(0) 85 42/1 69 90 www.micro-epsilon.com Modifications reserved / 9781181-A010099FHF
