Introduction

Liquid filled pressure gauges are an essential component in various industrial applications. They provide accurate pressure readings under fluctuating conditions and offer enhanced durability. This article examines the purpose of liquid filled pressure gauges, their advantages, key technical parameters, and solutions offered by Guanshan Instruments.

Purpose of a Liquid Filled Pressure Gauge

The primary purpose of a liquid filled pressure gauge is to provide accurate and stable pressure readings in dynamic environments. The liquid filling, often glycerin or silicone, dampens the oscillation of the pointer caused by equipment vibrations or pulsations in the medium being measured. This dampening effect prevents damage and wear to the moving parts, extending the lifespan of the gauge.

Technical Specifications and Parameters

Liquid filled pressure gauges are designed with specific technical parameters to ensure efficiency and accuracy:

• Pressure Range: Typically from 0 to 15,000 PSI, adjustable based on application needs.
• Accuracy: Standard accuracy of ±1% of full scale; precision models can reach ±0.5%.
• Temperature Range: Operational range from -40°F to 200°F (-40°C to 93°C).
• Case Material: Options include stainless steel and brass for corrosion resistance.
• Dial Size: Common sizes range from 1.5 to 6 inches for visibility under different conditions.

Advantages of Liquid Filled Pressure Gauges

Liquid filled pressure gauges offer numerous advantages over their dry counterparts:

• Vibration Dampening: The liquid absorbs vibrations, leading to more readable measurements.
• Extended Lifespan: Reduced wear and tear on internal components due to fewer oscillations.
• Microscopic Leak Prevention: The liquid prevents air from entering the gauge, which can cause inaccuracies.

Applications of Liquid Filled Pressure Gauges

These gauges are employed in various sectors, including:

• Hydraulic Systems: For stable monitoring in systems with frequent pressure changes.
• Chemical Processing: Resistant to corrosive substances due to protective liquid layer.
• Marine Applications: Function well in environments with constant motion and humidity.
