Introduction

Pressure gauges are essential tools in a variety of industries for monitoring fluid pressure levels. Liquid filled pressure gauges are specifically designed to enhance performance and durability under challenging conditions. This article examines the various benefits of liquid filled pressure gauges and highlights solutions offered by Guanshan Instruments.

Benefits of Liquid Filled Pressure Gauges

Vibration and Pulsation Dampening

Liquid filling, typically with glycerin or silicone oil, acts as a damping mechanism to reduce the effects of vibration and pulsation, which can cause undue wear and erratic readings. This can enhance the accuracy and reliability of the pressure measurement by up to 30% in environments with high mechanical vibrations.

Improved Longevity

The internal liquid helps lubricate and protect the moving parts of the gauge. This lubrication reduces friction and minimizes wear and tear, significantly extending the life of the gauge by approximately 20-40% compared to dry gauges in similar conditions.

Accurate Readings

By damping the pointer's motion, liquid filling prevents pointer oscillation, ensuring more stable and precise pressure readings. In environments where gauge accuracy is critical, such as in hydraulic systems, liquid filled gauges can maintain a precision of ±1% full scale, compared to ±2% for dry gauges.

Temperature Compensation

Liquid filling helps to stabilize the internal temperature of the gauge, mitigating the impact of external temperature fluctuations which can cause errors. This feature allows for consistent readings in a temperature range from -20°C to 60°C.
