TESA THE SPECIALISTS FOR LONG LENGTHS

1 TESA THE SPECIALISTS FOR LONG LENGTHS Large sizes mechanical engeerg mean dimensions excess of 500. Besides various measurement procedures like those that apply large ternal or external micrometers with two-pot contact, tape rules (wrappg round the outside diameter), V-bases, rotatg measurg disks (rollg-contact) and optical systems (triangu lation with theodolites), resort is often to make use of simple testg means like fixed gauges (side calliper gauges), gauge blocks combations or telescopic adjustable gauges. For large dimensions from 250 up to several meters, TESA offers various types of measurg struments that have long proven their value practical use. Here s an example of a proportional relationship. With a bore of 1200 H7, the tolerance zone is 0,1. Reducg both values by a factor of 100 would give a manufacturg tolerance as low as 1 µm. Of course, thgs are not as simple, but this example gives some ideas about the proportions. Whatever the sizes, from a simple distance between two surfaces parallel to one another to large diameters, their measurement is always a challenge to take up. Apart from the usual fluences, which are proportional to the size and add to your contributions the uncertaty budget, those due to gravity play a key role distortion. D-2

3 TESA UNIMASTER Universal Measurg Instrument Provides the features necessary for direct measurement of specially large ternal and external dimensions. TESA UNIMASTER is similar to ternal micrometers with two-pot contact with the workpiece. Performs direct measurement of any dimension with the extended application range by simply addg the needed extensions with built- gauge blocks to the measurg element. Accurate, robust and easy-to-handle Can be used either vertically or horizontally with a constant measurg force Incorporates a lever-type dial test dicator that clearly shows the culmation pot Ensures stable measurg owg to both negligible deflection and thermal protection on each extension.
