Scale/Dial Plate: Temperature Range -40°C to +120°C

Component Specifications

Definition

A precision-engineered circular component featuring graduated markings, indices, or numerical values that provide visual reference for measurement readings, operational parameters, or control settings in industrial machinery display systems. It serves as the primary interface for operators to interpret analog data from instruments like pressure gauges, flow meters, temperature indicators, and control dials.

Working Principle

Operates through mechanical or electromechanical coupling with a pointer or indicator that aligns with calibrated markings on the plate. The scale/dial plate converts rotational or linear movement into readable values through precisely spaced graduations, enabling accurate measurement interpretation and parameter monitoring.

Materials

Typically manufactured from aluminum alloys (6061-T6), stainless steel (304/316), tempered glass, polycarbonate, or engineered plastics (ABS, acrylic) with printed or etched markings using laser engraving, screen printing, or photochemical etching for durability and precision.

Frequently Asked Questions

What is the difference between a scale plate and a dial plate?

Scale plates typically refer to linear measurement surfaces with graduated markings, while dial plates are circular components with radial markings. In industrial contexts, the terms are often used interchangeably for circular display components.

How are markings applied to industrial scale/dial plates?

Markings are applied through laser engraving for permanent etched markings, screen printing for high-contrast colored markings, or photochemical etching for precision micro-markings. Each method offers different durability, precision, and cost characteristics.

What factors affect the accuracy of scale/dial plate readings?

Accuracy depends on graduation precision, marking clarity, parallax error minimization, proper illumination, operator viewing angle, and environmental factors like vibration and temperature that may affect the indicator mechanism.
