Product Overview

The YE Series Stainless Steel Capsule Pressure Gauge is designed for measuring very low pressure and micro pressure in gas systems.

It uses a sensitive capsule element formed by two elastic diaphragm discs welded together. 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.

Compared with conventional Bourdon tube pressure gauges, the capsule sensing element provides higher sensitivity for very low pressure measurement.

With a measuring range of 0–1.6 kPa, Class 2.5 accuracy, and stainless steel construction, this gauge is suitable for monitoring air and non-corrosive gases in ventilation systems, cleanrooms, gas pipelines, and other low-pressure applications.

Applications

The YE Series capsule pressure gauge is designed for low-pressure gas measurement. Typical applications include:

• HVAC ventilation systems

• Cleanroom pressure monitoring

• Gas pipelines

• Gas burners

• Boiler ventilation systems

• Pneumatic equipment

• Filter monitoring systems

• Laboratory equipment

• Environmental control systems

The measured gas should be compatible with the wetted materials. Please confirm the gas composition and operating conditions before selection.

Key Features and Benefits

FAQ

Q1: What is a capsule pressure gauge used for?

A: It is used to measure very low pressure and micro pressure, mainly in air and gas systems.

Q2: What is the measuring range of this model?

A: The standard measuring range is 0–1.6 kPa. Other measuring ranges can be customized according to customer requirements.

Q3: What is the difference between a capsule pressure gauge and a Bourdon tube pressure gauge?

A: A capsule pressure gauge uses a sensitive capsule element for very low pressure measurement, while a Bourdon tube gauge is generally used for higher pressure ranges.

Q4: Which gases can this gauge measure?

A: It is listed for air, gas, and non-corrosive gas applications. Material compatibility should be checked for the actual gas.

Q5: What dial sizes are available?

A: The listed dial sizes are 60 mm, 100 mm, and 150 mm.

Q6: Can the pressure range and connection be customized?

A: Customized pressure ranges and connection requirements can be discussed according to the application.
