Scale Plate: Accuracy Grade ±0.01 mm to ±0.1 mm

Component Specifications

Definition

A precision-engineered component featuring graduated markings or engravings that serves as the reference surface in position indicators, enabling accurate visual or automated reading of linear displacement, rotational angle, or positional coordinates in mechanical systems. It interfaces with pointers, sensors, or optical readers to provide quantitative feedback for control and monitoring applications.

Working Principle

Operates by providing a fixed, calibrated reference surface with precise graduations. A moving pointer, encoder, or optical sensor aligns with these markings to translate physical position into measurable units (e.g., millimeters, degrees). The scale's accuracy ensures reliable positional feedback through direct visual interpretation or electronic signal generation via integrated sensors.

Materials

Typically manufactured from stainless steel (e.g., AISI 304/316 for corrosion resistance), aluminum alloy (for lightweight applications), or glass (for high-precision optical systems). Surface treatments may include anodizing, etching, or laser engraving to ensure durability and legibility.
