Introduction

Pressure gauges are critical components in various industrial systems, providing vital data on pressure levels. To enhance their performance and durability, many gauges are filled with liquids like glycerin. This article examines the purpose of glycerin in pressure gauges, its benefits, and the solutions offered by Guanshan Instruments.

Function of Glycerin in a Pressure Gauge

Glycerin serves as a damping fluid in pressure gauges. It fills the interior casing of the gauge, surrounding the mechanical components. This viscous fluid dampens the movement caused by system vibrations, thus reducing wear and tear. Additionally, it minimizes pointer jitter, facilitating accurate readings even in fluctuating environments.

Benefits of Glycerin-Filled Pressure Gauges

• Minimized Vibrations: Glycerin absorbs vibrations, ensuring the precision of the gauge under dynamic conditions.
• Extended Lifespan: By reducing mechanical wear, glycerin-filled gauges exhibit a longer operational life.
• Temperature Stability: The presence of glycerin offers better temperature stability, functioning effectively within a range of -20°C to 60°C.
• Improved Accuracy: By dampening fluctuations, glycerin enables consistent, steady readings, crucial for processes requiring precise pressure control.

Numerical Analysis

The impact of glycerin on pressure gauge reliability is notable in terms of vibration resistance and accuracy. Tests indicate a reduction in mechanical failure by up to 67% and an accuracy improvement margin of 15% in environments with variable pressure oscillations. Glycerin maintains viscosity from 4-6 Poise, ideal for damping without hindering the gauge mechanism.
