Capsule Pressure Gauge

Capsule Pressure Gauge measures very low pressures (like millibars) using a sensitive, sealed metal capsule (two diaphragms welded together) that flexes with pressure changes, translating these tiny movements into a readable gauge indication, ideal for clean gases, aggressive fluids, and applications needing high sensitivity and overload protection.

Product Description

How it works

Core Component: Two corrugated diaphragms are welded to form a capsule.
Sensing: When low pressure is applied, the capsule deflects (bulges) outwards or inwards.
Indication: This deflection moves a pointer via a linkage mechanism to display the pressure on a dial.

Key Features & Benefits

Low-Pressure Measurement: Excellent for extremely low pressures, starting around 16 mbar.
High Sensitivity: Large effective area of the diaphragms provides precise readings for small pressure changes.
Overload Protection: Can withstand significant overpressure (e.g., 50x full scale) without damage.
Versatile: Suitable for gaseous, aggressive, and clean media, often made of stainless steel.
