Type of Pressure Gauges
||Regular Pressure Gauge (Non-Liquid Filled)||
||Liquid-Filled Pressure Gauge (e.g., Glycerin or Silicone)||
1. Regular Pressure Gauge (Non-Liquid Filled)
Description:
This type of gauge does not contain any liquid inside its housing, leaving the face dry and transparent. The pointer moves freely within the enclosure.
Advantages:
Cost-effective and budget-friendly.
Ideal for systems with stable pressure and minimal vibrations.
Easier to maintain and clean due to the absence of fluid.
Disadvantages:
In environments with vibrations or rapidly fluctuating pressure, the pointer tends to vibrate, making readings less accurate.
More prone to internal moisture buildup, which can lead to rust and corrosion.
Shorter lifespan in harsh or demanding environments.
2. Liquid-Filled Pressure Gauge (e.g., Glycerin or Silicone)
Description:
This type is filled with a clear liquid, typically glycerin or silicone, which surrounds and protects the internal components.
Advantages:
Vibration Dampening:
The fluid absorbs shocks and minimizes pointer movement, ensuring a steady and accurate reading even under fluctuating pressure.
Protection from Dust and Moisture:
The liquid seals the interior, preventing the entry of moisture and airborne contaminants, thereby reducing the risk of corrosion.
Extended Durability:
These gauges offer a longer service life, especially in harsh environments such as factories, gas stations, and outdoor fields.
Reliable Performance in Tough Conditions:
Ideal for areas with high temperatures, mechanical vibrations, and exposure to chemicals.
Disadvantages:
Higher in cost compared to standard, non-filled gauges.
The liquid may leak if the gauge is damaged or compromised.
Glycerin can thicken or solidify in extremely low temperatures, which is why silicone is sometimes preferred for colder climates.
When to Use Each Type?
Non-Liquid Filled Gauges:
Best suited for quiet, controlled environments with stable pressure and minimal vibration.
Liquid-Filled Gauges:
Recommended for high-vibration environments, areas with fluctuating pressure, elevated temperatures, or exposure to harsh external elements.
