Standard Dry Type Manometer-Steel
-
0.00 ~ 0.00/
1/ (Min. Order)
A dry-type manometer (also known as a mechanical pressure gauge) utilizes a Bourdon tube or diaphragm mechanism without liquid filling (e.g., glycerin or silicone oil). It is suitable for measuring gas or low-viscosity liquid pressure, offering vibration resistance, temperature tolerance, and maintenance-free operation. Steel (carbon steel/stainless steel) models are widely used in industrial applications.
Key Features
✔ No Liquid Filling – Eliminates leakage risks, ideal for vibrating or tilted environments.
✔ Robust Construction – Steel housing + internal mechanical structure ensures high impact resistance.
✔ Wide Pressure Range – Typically covers -1~0 bar (vacuum) to 0~1000 bar (high pressure).
✔ Multiple Connection Types – Options include G (parallel thread), NPT (American tapered thread), BSP (British standard thread), etc.
✔ Environmental Adaptability – Broad operating temperature range (-20°C to +80°C), extendable for special models.
Comparison: Carbon Steel (CS) vs. Stainless Steel (SS) Dry-Type Manometers
| Feature | Carbon Steel (CS) | Stainless Steel (SS, e.g., 304/316) |
|---|---|---|
| Corrosion Resistance | Moderate (requires coating) | Excellent (316 resists acids/seawater) |
| Mechanical Strength | High (cost-effective) | High (superior wear resistance) |
| Cost | Low | Higher (~2-3x carbon steel) |
| Compatible Media | Air, inert gases, oils | Corrosive gases/liquids (e.g., chemicals) |
| Hygienic Compliance | Not for food/pharma | FDA/EHEDG certified |
Typical Applications
-
Carbon Steel (CS): Air compressors, pneumatic tools, hydraulic systems (non-corrosive environments).
-
Stainless Steel (SS): Chemical pipelines, ship ballasts, food & beverage equipment, pharmaceutical cleanrooms.
Additional Selection Tips
-
Overload Protection: Choose models with a safety relief valve if pressure frequently exceeds the range.
-
Accuracy Class: Standard industrial use: Class 1.6 (±1.6% FS); precision control: Class 0.5.
-
Special Requirements: Custom options include explosion-proof (Ex d), sanitary (triple-diaphragm), etc.
For specific brand recommendations (WIKA, Ashcroft, Yokogawa) or installation guidance, please provide:
-
Media type (e.g., steam, compressed air)
-
Pressure range (e.g., 0–10 bar)
-
Environmental conditions (temperature, outdoor/explosion-proof requirements)
