Liquid Filled Stainless Steel Capsule Pressure Gauge for Micro Pressure Measurement

Overview

The Stainless Steel Liquid Filled Capsule Pressure Gauge is specially designed for micro pressure and low pressure measurement applications.

It uses a sensitive capsule element as the pressure sensing component. Compared with traditional Bourdon tube pressure gauges, the capsule structure provides a larger sensing area and higher sensitivity, allowing accurate measurement of very small pressure changes.

The liquid-filled case design effectively reduces pointer vibration caused by mechanical shock and pressure pulsation, ensuring stable readings in demanding industrial environments.

With all stainless steel construction, 0~60kPa measuring range and Class 2.5 accuracy, this gauge is ideal for measuring low pressure air and gas in ventilation systems, combustion equipment and industrial processes.

Application

The Liquid Filled Capsule Pressure Gauge is mainly used for micro pressure and low 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

Special Advantages Compared with Normal Pressure Gauges:

1. Designed for Micro Pressure Measurement

Traditional Bourdon tube pressure gauges are usually used for medium and high pressure measurement. Capsule pressure gauges are specially designed for very low pressure ranges such as kPa, mbar and mmH2O levels.

2. Higher Sensitivity

The capsule sensing element can detect smaller pressure changes due to its flexible diaphragm structure.

3. Better Vibration Resistance

The filled liquid inside the case absorbs mechanical vibration and pressure pulsation, improving pointer stability and service life.

4. Suitable for Gas Applications

Especially suitable for clean, dry and non-corrosive gases where accurate low pressure measurement is required.
