Pressure gauge pointer and dial assembly for visual pressure indication in industrial systems.
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.

Pointer sticking typically results from friction in pivot bearings, contamination by process media, mechanical damage to gears, or magnetic interference in certain environments.
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.
Yes, dials can be manufactured with dual scales (psi/bar, kPa/MPa), logarithmic scales, or application-specific markings for temperature, flow, or vacuum equivalents.
