Maritime shipping is the primary mode of global trade, accounting for over 80% of the total global trade volume. Approximately 95% of China's international trade cargo volume is transported via maritime shipping. With the continuous growth of international trade, the demand for ship navigation has been expanding steadily.
In 2023, the total global order intake for oil tankers reached 28.71 million deadweight tons, 3.2 times that of 2022; the order backlog at the end of 2023 stood at 47.85 million deadweight tons, a year-on-year increase of 59.1% compared to 2022. In 2023, the number of newly completed LNG (Liquefied Natural Gas) ships was 41, a year-on-year growth of 20.6%, and the order backlog at the end of 2023 was 341 ships, a year-on-year increase of 5.2% compared to 2022.
With the application of new materials, new energy sources, and intelligent technologies, ship performance has been significantly improved. Low-carbon and clean energy sources are adopted to replace traditional fuel oil, reducing the impact of ship emissions on the environment. The pressure and liquid level monitoring of various ship operating systems have placed more stringent requirements on industrial instruments, such as resistance to vibration, high humidity and high salt environments, flammable and explosive hazards, measurement of corrosive media, and classification society certification requirements.
Shipbuilding is the core of the ship industry. Ships have a large-scale control system, including fuel supply systems, ballast water management systems, ship exhaust gas desulfurization and denitrification systems, etc. According to operating conditions, there are professional measurement needs for the pipeline pressure of each system and the liquid level of cargo holds.
The dial and pointer of the marine luminous pressure gauge have undergone special treatment and are coated with permanent luminous agents. This design allows crew members to clearly read the pressure value even in pitch-black nights, dimly lit cabin interiors, or emergency situations such as sudden power outages. During night navigation, the lights in the cockpit need to maintain a certain brightness to ensure that crew members can observe the external environment. Under such circumstances, ordinary pressure gauges may be difficult to read clearly due to light interference. However, the matte display function of the luminous pressure gauge perfectly solves this problem, enabling crew members to keep track of the pressure status of various ship systems at all times and promptly detect potential safety hazards.
During a ship's navigation, it will be affected by factors such as ocean waves and sea winds, resulting in severe vibration and swaying. The interior of the marine luminous pressure gauge is filled with damping fluid, such as silicone oil. This not only can effectively reduce the impact of vibration on the pointer, allowing the pointer to stably indicate the pressure value even in a vibrating environment, but also can extend the service life of the pressure gauge. Even when the ship encounters severe sea conditions, with large-scale pitching and intense vibration, the marine luminous pressure gauge can still work normally, providing reliable pressure monitoring data for the ship's power system, hydraulic system, pneumatic system, etc.
The marine environment is humid and rich in salt, which is highly corrosive to equipment. The marine luminous pressure gauge has a waterproof performance reaching IPX4 or higher, which can effectively prevent seawater from splashing into the gauge and avoid damage to internal components due to water ingress. At the same time, key parts such as its case and bourdon tube are made of materials resistant to seawater corrosion, such as special copper alloys and stainless steel, which have excellent salt spray corrosion resistance. This ensures that during long-term marine navigation, the measurement accuracy and normal operation will not be affected by the erosion of seawater and salt spray.
The accuracy classes of marine luminous pressure gauges usually include 2.5, 1.6, and 1.0, which can meet the high-precision requirements of ship equipment for pressure monitoring. In the ship's propulsion system, the pressure of the engine lubricating oil needs to be accurately controlled within a certain range. Excessively high or low pressure may lead to engine failures. The marine luminous pressure gauge can accurately measure the lubricating oil pressure. Once the pressure is abnormal, crew members can take measures to adjust it, ensuring the normal operation of the engine and thus guaranteeing the navigation safety of the ship.
In the power equipment of ships, such as engines and boilers, marine luminous pressure gauges are used to monitor the pressure of media such as fuel oil, lubricating oil, and cooling water. The stability of engine fuel pressure is crucial for ensuring sufficient combustion and stable power output, while the lubricating oil pressure is related to the lubrication effect of various engine components, preventing damage to components due to wear. By real-time monitoring these pressure parameters, crew members can promptly detect potential problems in the power system, such as poor fuel supply and lubricating oil leakage, and take corresponding maintenance measures to ensure the normal operation of the ship's power system.
The ship's steering gear, loading and unloading equipment, etc., usually adopt hydraulic or pneumatic systems to provide power. The marine luminous pressure gauge can monitor the pressure of hydraulic oil or compressed air in these systems to ensure the normal operation of the equipment. When the ship berths at a port, the anchor windlass needs stable hydraulic pressure to retract and lower the anchor chain. If the hydraulic system pressure is insufficient, it may cause the anchor chain to fail to operate normally, affecting the safety of the ship's berthing. The marine luminous pressure gauge can feedback the pressure status of the hydraulic system in real time, ensuring the smooth progress of various ship operations.

The ship's fire-fighting system is an important line of defense to ensure ship safety. The marine luminous pressure gauge is used to monitor the water pressure in the fire-fighting water pipeline, ensuring that when a fire breaks out, the fire-fighting system can provide sufficient pressure to spray fire-extinguishing agents. At night or in emergency situations, crew members can quickly understand the pressure status of the fire-fighting system through the luminous pressure gauge, start the fire pump in a timely manner, ensure the normal supply of fire-fighting water, and gain valuable time for extinguishing the fire.
