Pointer: Rotation Range 270-300 degrees, Weight 2-15 grams

Component Specifications

Definition

A precision mechanical component within pressure gauge assemblies that rotates proportionally to pressure changes, translating Bourdon tube or diaphragm movement into visual readings on calibrated dials. It serves as the primary human-machine interface for pressure monitoring in industrial applications.

Working Principle

Operates through mechanical linkage to pressure-sensing elements (typically Bourdon tubes, diaphragms, or bellows). Pressure changes cause sensing element deformation, which transfers motion through gears or levers to rotate the pointer along a calibrated scale, providing analog pressure readings.

Materials

Typically aluminum alloys (6061-T6, 7075) for lightweight strength, stainless steel (304, 316) for corrosive environments, or engineered plastics (POM, PEEK) for chemical resistance. Surface treatments include anodizing, powder coating, or laser etching for durability and legibility.

Frequently Asked Questions

What causes pointer oscillation in pressure gauges?

Pointer oscillation typically results from pulsating pressure sources, mechanical vibration, or worn linkage components. Dampening solutions include liquid-filled gauges, restrictor valves, or snubbers.

How do you calibrate a pressure gauge pointer?

Calibration involves applying known pressure values and adjusting zero and span screws to align pointer with reference points. Professional calibration follows ISO/IEC 17025 standards using deadweight testers or digital calibrators.

Can pressure gauge pointers be replaced individually?

Yes, but replacement requires matching shaft dimensions, weight balance, and mounting style. Professional replacement ensures proper calibration and prevents damage to movement mechanisms.
