The variable is composed of an interchangeable contact type plain plug gauge head, which serves as the measuring element of the instrument, and a handle that controls the signal conversion and transmission. This gauge can be equipped with either a mechanical transmission gauge head (MBG) or an electronic transduction gauge head (EBG).
The gauge head is an extremely versatile solution, capable of gauging deep or interrupted bores. The mechanical transmission measuring system provides excellent metrological performance with a repeatability of less than 1 micron, while also being cost-effective. The ability to configure and interchange a wide range of accessories makes this gauge head universally applicable. The measuring cell consists of either two or eight fulcrum elements, depending on the diameter. Measurements are transduced to the display device via a transfer rod with a spherical head that slides on a cradle formed by a V-shaped guide and an inclined plane.
