Introduction

Liquid-filled pressure gauges are pivotal in industries requiring precise pressure measurement under challenging conditions. This article delves into their purpose, advantages, and specific applications, highlighting the solutions provided by Guanshan Instruments.

Functionality of Liquid-Filled Pressure Gauges

Liquid-filled pressure gauges contain a liquid, usually glycerin or silicone, that surrounds the internal components. This liquid serves multiple purposes, including damping environmental vibrations and minimizing pointer fluctuation, ensuring accurate readings.

Advantages of Using Liquid-Filled Pressure Gauges

Liquid filling offers several benefits, such as:

• Providing lubrication for internal movements, reducing wear and tear.
• Protecting against condensation in humid environments, extending the gauge's lifespan.
• Enhancing readability by stabilizing the pointer under dynamic conditions.

Common Applications

These gauges are vital in environments where mechanical vibrations are prevalent, such as:

• Hydraulic systems.
• Pressure washers.
• Refineries.
• Energy generation plants.

Performance Parameters

Key performance parameters for liquid-filled pressure gauges include:

• Accuracy class: Typically ranges from ±1% to ±2% of full-scale deflection.
• Pressure range: Can vary from 0 to 15,000 psi, suitable for diverse applications.
• Operating temperature: Usually between -40°F to 150°F (-40°C to 65°C) without compromising performance.
