An electrical comparator that converts the mechanical displacement of the measuring element into an electrical quantity and indicates it as a deflection of the pointer. There are inductive, resistive, and capacitive types depending on the conversion method. They have features such as the ability to separate the measurement location from the indication location and a high magnification, but fluctuations in the power supply affect their accuracy. Traditionally, most were analog types, but recently digital types that use an AD converter have become popular. → Related itemsComparative length measuring device|Micrometer Source : Heibonsha Encyclopedia About MyPedia Information |
測定子の機械的変位を電気量に変換し指針の振れとして示す電気的コンパレーター。変換方式により誘導形,抵抗形,容量形などがある。測定場所と指示位置が分離でき,倍率が大などの特色があるが,電源の変動は精度に影響する。従来はほとんどがアナログ型であったが,最近はAD変換器を介在させたデジタル型のものが普及してきている。 →関連項目比較測長器|マイクロメーター 出典 株式会社平凡社百科事典マイペディアについて 情報 |
