MaraMeter. Indicating Measuring Instruments for Inside Measurements Indicating Plug Gages 844 D Features For the rapid testing of diameter roundness and conicity of bores Especially suitable for testing batches with tight tolerances No rocking in the bore is required to determine the reversal point Therefore ideal for use in conjunction with a digital indicating instrument and for subsequent processing of measured values Measuring head has a hardened hard chromium plated guide cylinder and carbide-tipped anvils The carbide expanding pin transfers radial movement to indicating instrument Constant measuring force as a result of built-in spring thus eliminating user influence Measuring head holder depth extension right angle attachments and depth stops are part of an extensive modular system Technical Data of the Measuring Heads Nominal diameter of the bore Measuring range starting from the minimum bore dimension to be measured 844 Dk 844Dkr 2.98 -over 8 -over 16 -over 32 - 8 mm 16 mm 32 mm 70 mm over 70 - 200 mm - 0.02 - 0.02 - 0.02 - 0.03 - 0.04 0.1 mm 0.15 mm 0.2 mm 0.2 mm 0.2 mm 844 Dks (from 4 mm) - 0.02 0.1 mm - 0.02 0.15 mm - 0.02 0.15 mm - 0.03 0.15 mm - 0.04 0.15 mm Accuracy Hystersis 0.4 m Repeatability 1 m Linearity 1 % Linearity 844 Dks 16 mm 2 % When placing an order please quote the nominal diameter and tolerances for example Bore diameter Tolerance 35 D7 80 105 m 35 H7 0 25 m 35 R7 - 50 -25 m contact point expanding pin The diameter of the guide cylinder is produced between 0.02 and 0.07 mm smaller than the minimum dimension of the bore to be checked.
