Pressure Gauge Models

As a key instrument for measuring fluid pressure, pressure gauge selection requires a comprehensive consideration of its operating principle, type, and technical specifications. Mechanical pressure gauges (such as those with spring tube structures) are suitable for traditional industrial applications, while electronic pressure gauges (using pressure sensor conversion) are more suitable for high-precision digital applications. Common types include standard (0.1-60 MPa range), shock-resistant (vibration-resistant), and electric contact (with alarm function), with accuracy levels ranging from Class 1.0 (±1% error) to Class 0.1 (±0.1% error). Key selection parameters include range matching (e.g., 0-4 MPa is commonly used for boiler monitoring), port size (e.g., G1/2 thread standard), and environmental compatibility (explosion-proof rating Ex dⅡCT6). The base model should be tailored to the installation scenario: radial bases (carbon steel) are suitable for direct pipe installation, universal bases (304 stainless steel) offer 360° adjustment, and axial bases address non-concentric installation issues.
