ATF-100H Pressure Gauge 0~5bar/0~70psi 3/8G SUS304

Main Components of ATF-100H Pressure Gauge/Lower Thread (Pressure Gauge) 0~5bar/0~70psi 3/8G SUS304

The ATF-100H Pressure Gauge/Lower Thread (Pressure Gauge) 0~5bar/0~70psi 3/8G SUS304 is a convenient and easy-to-use oil-free pressure gauge with side-mounted pointer, suitable for various industries.

• Bourdon Tube: A curved metal tube in the shape of a C or oval that expands when pressurized
• Gear & Pointer Mechanism: Converts the expansion of the Bourdon tube into the rotation of the measuring needle
• Housing: The back or side has an external shaft for installation purposes
• Dry Type (Oil-free): No glycerin oil inside, suitable for non-vibrating environments                     

Working Process of ATF-100H Pressure Gauge/Lower Thread (Pressure Gauge) 0~5bar/0~70psi 3/8G SUS304

The pressure from liquids or gases (such as air, water, oil, etc.) enters the Bourdon tube, causing it to expand slightly. As the pressure increases, the end of the tube moves. The end of the Bourdon tube is connected to a gear mechanism that converts linear movement into needle rotation. The needle rotates to a position corresponding to the measured pressure on the dial.                                                  

Advantages of Oil-free (Dry Gauge) Type:

• Lightweight
• Suitable for general use in non-high vibration environments
• Used in systems with infrequent pressure changes, easy to maintain

Usage Examples:

• Air compressor system
• Potable water system
• Mild hydraulic systems without severe vibrations
• General industries
