Magnetic Grating Ruler: Pitch and Accuracy Relationship

The magnetic grating ruler is a common measurement device whose accuracy is influenced by multiple factors. The grating pitch is an important parameter that affects precision.

The grating pitch refers to the distance between adjacent reference marks, typically expressed as the number of marks per unit length. A smaller pitch means more marks per unit length, which generally leads to higher measurement accuracy. In practice, grating pitch is one factor among others, such as the read head accuracy, installation method, and ambient temperature, that determine overall measurement precision.

In summary, a smaller grating pitch generally corresponds to higher accuracy, but one should consider other factors in real applications to ensure required precision and reliability.
