TESA DIAL GAUGES ELECTRONIC AND ANALOGUE EASY-TO-USE AND VERSATILE For more than 50 years we have been producing and distributing a wide range of easy-to-use and versatile dial gauges. Our experience allows us to offer a wide choice of different models. Electronic indicators with combined analogue digital display using the most up-to-date technology. Mechanical dial gauges equipped with high-precision movements and double-action shockproof mechanisms. Measuring spans up to 100 mm. choice of dial gauge or electronic indicator Digital indication provides error-free reading of the measured value. There is no need to read fractions of scale divisions. Analogue indication offers the advantage of being able to smoothly adjust the increase or decrease of the dimension to be measured on the workpiece. This type of indication is best suited for dynamic MEASUREMENTs such as determining axial and radial runout errors. Electronic indicators provide many additional functions compared to the mechanical models. For more information refer to the section on electronic indicators. The inspection of axial and radial runout errors frequently requires the use of instruments with the lowest hysteresis characteristic. Our electronic indicators precision dial gauges and dial test indicators meet this requirement. In order to significantly reduce the effect of systematic errors it is recommended to carry out comparative MEASUREMENTs. Only deviations from the nominal dimension will be displayed. High precision small range electronic indicators are the ideal instruments for these types of MEASUREMENTs. These same instruments also enable avoiding major errors in reading millimetres. STANDARDS AND DEFINITIONS The international ISO 463:2006 standard replaces national standards dealing with mechanical dial gauges. All the same new definitions and standard requirements pertaining to measuring procedures although valid imply changes in design and metrological characteristics which cannot be entirely indicated in this catalogue. This standard is defined in the matrix "Product Specification (GPS) dimensional measuring instruments". It only defines the requirements for the most important characteristics. Therefore all tolerance limits indicated in this catalogue which refer to metrological characteristics are based on our own internal standards.
