Component Specifications

Definition
The pointer and dial assembly is a critical visual interface component of a pressure gauge, consisting of a calibrated dial face with pressure markings and a movable pointer that rotates proportionally to pressure changes. This assembly translates mechanical movement from the gauge's sensing element into readable pressure values through angular displacement of the pointer against the graduated dial scale.
Working Principle
The pointer is mechanically linked to the gauge's movement mechanism (typically a Bourdon tube, diaphragm, or capsule). Pressure changes cause deflection in the sensing element, which is transmitted through gears or linkages to rotate the pointer. The pointer's angular position corresponds to specific pressure values marked on the stationary dial, allowing operators to read pressure through visual alignment.
Materials
Dial: Aluminum alloy, stainless steel, or polycarbonate with printed/etched markings. Pointer: Aluminum, brass, or stainless steel with counterweight. Pivot: Stainless steel or jewel bearing. Markings: Enamel, laser etching, or screen printing.

Frequently Asked Questions

What causes pointer sticking or sluggish movement?

Pointer sticking typically results from friction in pivot bearings, contamination by process media, mechanical damage to gears, or magnetic interference in certain environments.

How often should pointer and dial be calibrated?

Calibration intervals depend on application criticality: typically 6-12 months for general industrial use, 3-6 months for critical processes, following ISO 9001 or industry-specific standards.

Can dial scales be customized for different units?

Yes, dials can be manufactured with dual scales (psi/bar, kPa/MPa), logarithmic scales, or application-specific markings for temperature, flow, or vacuum equivalents.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
