While our SCAT and LCAT measuring heads can be used with a wide range of turbine brush-seal grooves, the latest µCAT (“mu-CAT” or “micro CAT”) fits where the others can’t. The latest turbines for power generation being developed include stages with very small radial clearance.
Low Radial Clearance
While our prior µCAT was the same width as the SCAT (0.500″), the new version is only 0.300″ wide to fit narrow brush-seal grooves, and like the older model, can measure radial clearances from 0.200″ to 0.250″. An adjustable “hat” can be installed on top to fit 0.300″ to 0.363″ brush-seal grooves, and SCAT shims and spacers can be installed to fit spacings 0.363″ to 0.500″ wide, at which point the SCAT head can be used.
