The SCHWENK Indicating Bore Gauge is a robust, intelligent plug gauge with a mechanical two-point contact comparator, where each gauge is tailored to suit a specific application.
The measurement application range is from 2.5mm to 800mm. The standard measuring range of an individual measuring sleeve is 0.2mm and hence the actual size to be measured must be specified together with its tolerance.
Output resolution depends upon the choice of output which may be mechanical dial or digital indicator. As with all comparative measuring methods, a suitable setting ring should be used.
The standard design measuring sleeve is available to cover internal diameters up to 130mm. Above this size, and to minimize the weight of the gauge, a cross sleeve design is employed. This OD series provides the highest level of accuracy and repeatability but is diameter specific. For all variants, deep bore extensions, blind bore and hard chrome plated versions are available.
