100mm Pressure Gauges

100mm Glycerine and Dry Gauges from Shelley Automation: Key Differences and Applications

Shelley Automation offers 100mm pressure gauges in both glycerine-filled and dry versions, with connection sizes of 3/8" for both options and an additional 1/2" option for the glycerine-filled gauge. These gauges have their own advantages and disadvantages, making them suitable for different applications. Here's a breakdown:

Glycerine-Filled Gauges (back and bottom connection available):

  • Vibration resistance: Ideal for environments with constant movement or shaking, like mobile machinery, engines, and compressors.
  • Reduced pointer flutter: Ensures accurate and consistent readings even with pressure fluctuations.
  • Corrosion protection: Glycerine protects internal components in humid or wet environments.
  • Larger dial: Enhanced readability compared to 50mm and 63mm options.
  • Higher cost: Compared to dry gauges.
  • Slower response time: Glycerine fill can slightly delay the gauge's response to pressure changes.
  • Mobile equipment and machinery exposed to vibration.
  • Hydraulic and pneumatic systems experiencing pressure fluctuations.
  • Applications requiring clear readability from a distance.

Dry Gauges (bottom connection):
  • More affordable: Lower cost compared to glycerine-filled gauges.
  • Faster response time: Reacts immediately to pressure changes.
  • Less suitable for vibration: Pointer may flutter and readings may be less accurate in shaky environments.
  • Corrosion risk: May be susceptible to corrosion in humid or wet environments.
  • Smaller dial: Less readability compared to larger glycerine-filled versions.
  • Stationary equipment with minimal vibration.
  • Applications where cost is a primary concern.
  • Situations where immediate response to pressure changes is crucial.
Additional Considerations:
  • Pressure range: Both types come in various pressure ranges to suit specific needs.
  • Accuracy: Both types typically offer ±2.5% FSD accuracy.
  • Durability: Both types are constructed for durability, typically made from steel with a black finish.
Choosing the Right Gauge - the best choice depends on your specific application and priorities. Consider:
  • Presence of vibration: If vibration is present, a glycerine-filled gauge is crucial for accurate readings.
  • Budget: If cost is a major concern, a dry gauge may be sufficient.
  • Pressure fluctuations: If pressure changes are frequent, a dry gauge offers a faster response.
  • Readability needs: For better readability from a distance, a larger glycerine-filled gauge is preferred.

By understanding the pros and cons of each type and considering your specific needs, you can choose the ideal 100mm pressure gauge from Shelley Automation for your application.
