Wide-range general-purpose digital head Γ-DⅡ
Features
Γ-DⅡ (Gamma -DⅡ) Has a Wide Range of Size Measuring
The Γ-DⅡ reduces the setting time for size changing.
Setting for size changing in the same workpiece does not need.
High Accuracy & Repeatability
High precision and minimization of thermal effect on measurement have been achieved by using optical scale system in the Γ-DⅡ .
The repeatability of Γ-DⅡ is less than or equal to 0.2 μm (the mean value obtained by measurement 25 times ± 4 σ ).
Accurate and Stable Measurement with High Responsiveness
The Γ-DⅡ function that follows the fluctuations of measuring-value has been improved.
IIt enables accurate and stable measurement with less error-occurring .
Compact Design and Slim Cable
The Γ-DⅡ is compact; essential functions are all in its body. And it does not need any relay boxes. The Γ-DⅡ also uses a slim cable, so it is easy to arrange the cable in building
the system which even has a narrow space, etc.
Application
・Measuring Inner diameter, Outer Diameter, Eccentricity and Difference in Level, etc.
