Brief introduction of air gasoline water pressure gauge: 1. It is suitable for measuring the pressure or vacuum of liquid, gas and steam medium that will not explode, crystallize or corrode components. 2. It can send electrical signals with certain electrical devices for automatic control and alarm. 3. Using magnetic quick-action contacts, the load is large, the output is stable, the contact life is long, and it has a certain buffer and damping effect. 4. It has an anti-vibration structure, which can suppress the oscillation and pulsation of the pointer, protect the contacts, and make the indication and electrical conversion reliable and stable. 5. With anti-corrosion function, it is suitable for measuring strong corrosive media and provides reliable signals for automatic control. 6. Widely used in machinery industry, chemical industry, metallurgy, petrochemical, mining, electric power, etc. 7. It is suitable for high-temperature working conditions (70-150°C), and sends out reliable alarm and control signals.
