Capsule Pressure Gauges

Capsule pressure gauges measure very low pressures and vacuum conditions in industrial process control systems. They employ a sensitive capsule element composed of two thin, flexible diaphragms joined together, which expands or contracts proportionally to changes in applied pressure or vacuum. This mechanical displacement translates into movement of a pointer on an analog dial, providing precise visual indication of pressure conditions.

Their sensitivity and accuracy at low-pressure ranges make capsule gauges invaluable in processes where precise monitoring of minute pressure variations is critical. They provide quick visual diagnostics, enhancing process safety, accuracy, and efficiency. Their robust yet sensitive construction ensures reliability even in delicate measurement scenarios.

Typical industrial applications include measuring gas pressures in laboratory instrumentation, cleanroom environments, HVAC systems, combustion systems, vacuum pumps, gas distribution networks, and pharmaceutical or food-processing equipment. Capsule gauges are especially suitable for monitoring filtration pressures, airflows, and leak detection processes requiring high sensitivity and precision.

Constructed from materials such as stainless steel or brass, capsule pressure gauges typically feature corrosion-resistant components suitable for demanding industrial environments. Options include liquid-filled casings for vibration damping, as well as hazardous area-certified models (ATEX, IECEx), ensuring precise performance and safe operation in challenging conditions.
