Capsule Pressure Gauges For HVAC Systems

Capsule Pressure Gauges are designed for measuring very low pressures of gases, typically in the range of a few millibars to hundreds of millibars. They use a capsule element made by joining two thin, corrugated diaphragms. When pressure is applied, the capsule expands or contracts, and this movement is transferred to a pointer on the dial through a mechanical linkage. These gauges are highly sensitive and are commonly used for applications such as air flow measurement, draft measurement in heating systems, leak testing, filter monitoring, and laboratory processes. They are particularly suited for non-corrosive and clean gases where precise low-pressure monitoring is required.
