PRODUCTS製品情報 水準器用測定ピッチ自在ベース OS-202

●本体は上質な鋳鉄製(FC250)で、天面・底面は平面・平行を精密に製作しています。
●真直度・平面度測定の測定ピッチ自在に測定できます。
●長側面にいは中心を0にした振り分けの目盛付スケールがあり、mm(ミリ)単位で正確にピッチを設定できます。

■定盤の平面度測定は、定盤の使用面呼び寸法により測定間隔(ピッチ)がJIS規格(JIS B7513)で定められております。水準器測定ピッチ自在ベースを水準器と併用することで、JIS規格に準拠した測定間隔を設定して正しい平面度計測が可能になります。
■水準器の感度は0.02mm(4秒)、0.05mm(10秒)と表現します。この数値は水準器の呼び寸法には関係なく、底辺1000mmに対する直角三角形の高さを表します。

●The main body is made of fine cast iron (FC250) and the top face and the bottom face are precisely made, taking their flatness and parallelism into account.
●Straightness and flatness can be measured by freely adjusting the measuring pitch.
●The long side has a graduated scale marked on it with a zero at the center. The measuring pitch can be set accurately in mm.
■The measuring interval (pitch) of the flatness of surface plates is determined by a JIS standard (JIS B7513).depending on the nominal size of the face where the surface plates are used. If an adjustable base for measuring pitch is combined with a level, it is possible to create a measuring interval that meets the JIS standard and measure flatness correctly.
■The sensitivity of a level is expressed as either 0.02mm (4seconds) of 0.05mm (10seconds). These values show the heights of right-angle triangles that have a base 1000 mm long, and are independent of the nominal size of a level.
