Product Overview

The YE Series Liquid Filled Stainless Steel Capsule Pressure Gauge is designed for micro-pressure and low-pressure measurement in gas systems.

It uses a sensitive capsule element as the pressure sensing component. When pressure enters the capsule, the element deforms slightly. This movement is transferred through a mechanical movement system to indicate the pressure on the dial.

The liquid-filled case is available with glycerin or silicone oil. The filling liquid helps damp pointer movement caused by mechanical vibration and pressure pulsation, providing more stable readings in demanding operating environments.

With a listed measuring range of 0–60 kPa and Class 2.5 accuracy, this gauge is suitable for monitoring air and non-corrosive gases in ventilation systems, combustion equipment, gas pipelines, and other industrial applications.

Applications

The YE Series liquid filled capsule pressure gauge is mainly used for low-pressure and micro-pressure gas measurement.

Typical applications include:

• Boiler ventilation systems

• Gas pipelines

• Gas burners and combustion equipment

• HVAC and air handling systems

• Pneumatic equipment

• Filter and airflow monitoring systems

• Industrial gas pressure control

• Environmental control equipment

Please confirm gas composition and material compatibility before selecting the gauge.
