Pressure gauges

1. Definition：
A pressure gauge is an industrial instrument used to measure and display the pressure of fluids (gases and liquids). It senses pressure through elastic sensitive elements (such as Bourdon tubes, diaphragms, bellows, or corrugated tubes), which deform under pressure. The transmission mechanism then drives the pointer or digital module to visually indicate the gauge pressure, absolute pressure, differential pressure, and other pressure values of the medium. It is widely used for pressure monitoring, safety alerts, and process control.

2. Key Features：

1. Wide measurement range: It can measure micro, low, medium, high, and ultra-high pressures, meeting the requirements for pressure detection under various working conditions.

2. Wide range of precision levels: From general industrial grade to precision measurement grade, featuring high measurement accuracy, minimal backlash, and excellent long-term stability.

3. Durable and sturdy structure: The mechanical structure is reliable, resistant to vibration and impact, and suitable for complex field environments.

4. Strong environmental adaptability: It possesses anti-corrosion, anti-rust, heat-resistant, and moisture-proof properties, and can be used in explosion-proof and highly corrosive environments.

5. Easy Installation: Supports radial, axial, embedded, and wall-mounted installation methods with standardized interface specifications.

6. Rich in functionality: It can achieve local display, remote transmission, upper and lower limit alarms, and magnetic-assisted electrical contact control.

7. Safe and reliable: Overpressure protection and explosion-proof structural design ensure the operational safety of equipment and personnel.

3. Applicable Industries:

1. Petrochemical: Pressure monitoring for oil and gas pipelines, reactors, storage tanks, compressors, and refining units.

2. Power Energy: Boilers, steam turbines, thermal power pipelines, water pumps, hydraulic systems, and auxiliary equipment pressure detection in power stations.
