Explosion-proof pressure switch – the preferred choice for mining applications Underground mines are high-risk and complex special working environments, generally characterized by explosive gases such as methane, combustible coal dust, high humidity, strong vibration, and dust accumulation.

As a core component for safety interlocking and control of industrial fluid, pneumatic, and hydraulic systems, pressure switches rely on precise pressure triggering and reset actions to ensure stable equipment operation.

Pressure switches serve as core protective components within industrial pressure control systems; the precision of their actuation and reset pressures directly impacts equipment operational safety and process stability.

Dual-flange differential pressure level gauges are available in various models based on their measurement principle, functional characteristics, measurement range, and installation method. By selecting the appropriate model, different working conditions can be met, avoiding measurement errors or equipment damage caused by improper selection.

When selecting differential pressure flow switches for large and medium-sized chiller units, it is necessary to comprehensively consider system characteristics, safety requirements, and equipment compatibility.

The daily maintenance of vortex flowmeters should focus on key aspects such as regular cleaning, pressure coefficient adjustment, component inspection, electrical maintenance, and troubleshooting to ensure measurement accuracy and long-term stable operation of the equipment.

The gas vortex flow meter utilizes the fluid vortex precession effect, integrates automatic temperature and pressure compensation, and is suitable for metering clean and dry gases such as natural gas and compressed air. It is an intelligent velocity flow meter with high accuracy, no mechanical wear, wide range, and easy installation and maintenance.

Metal float flowmeters measure flow rate by observing the positional changes of a float within a tapered tube. Their core principle is variable area flow measurement, which utilizes the balance between the pressure difference generated by the fluid flowing through the annular gap between the float and the tapered tube and the float’s weight to convert the flow rate into a linear relationship with the float’s height.

Metal tube float flowmeters, with their core advantages of simple structure, reliable measurement, and strong adaptability, are indispensable flow measurement instruments in industrial automation process control. They are particularly suitable for measuring small-diameter, low-flow-velocity, and complex media, and are widely used in industries such as petroleum, chemical, pharmaceutical, food, and water treatment.
