High-pressure gauge vs ordinary pressure gauge: a comprehensive analysis of core differences
1. Range difference
table
Type Measuring range Typical applications
General pressure gauge 0-1.6MPa ~ 0-10MPa Water system, air compressor, general industry
High-pressure gauge 0-10MPa ~ 0-100MPa Hydraulic system, chemical industry, boiler, petroleum
Ultra-high pressure gauge 0-100MPa ~ 0-600MPa Water jet, material testing, special operating conditions
2. Structural differences
Key differences between ordinary pressure gauge and high pressure gauge:
table
Comparison items: Ordinary pressure gauge, High-pressure gauge
Spring tube, C-type phosphor copper tube, C-type or spiral stainless steel tube
Interface thread: M10/M14, M20/M27, thickened thread
Case thickness: Standard, Thickened for shock resistance
Safety design Basic type Explosion-proof with pressure relief hole
Accuracy level: 1.6~2.5 level, 1.0~1.6 level
3. Reasons for not being able to mix them
Potential safety hazard: The spring tube of a regular pressure gauge cannot withstand high pressure and may rupture directly
Loss of accuracy: When measuring low-voltage signals with a high-voltage meter, the resolution is insufficient
Reduced lifespan: Overuse accelerates the fatigue of elastic components
4. Procurement decision tree
Is the working pressure greater than 10MPa?
├─ Yes → Choose a high-pressure gauge
│ └─ Is there vibration? → Oil-filled shockproof type
│ └─ Corrosive medium? → Stainless steel type
│ └─ High safety requirements? → Explosion-proof and pressure relief type
└─ No → A regular pressure gauge will suffice
