Industry Overview
In the shipbuilding and offshore engineering industry, key systems such as power and engine systems, LNG/LPG fuel gas systems, ballast water treatment, desulfurization and denitrification, cargo tank monitoring, and safety alarm systems typically require a comprehensive monitoring network for temperature, pressure, flow, and liquid level as core support. These systems are designed to meet demanding process conditions including high temperature, high pressure, high vacuum, and marine corrosive environments. Pressure and liquid level measurement systems serve as critical safeguards for ship safety operation and energy efficiency management. However, the complex marine environment poses severe challenges to real-time process parameter detection, such as long-term stability of sensors, seawater corrosion resistance, and measurement accuracy in high salt spray environments. By analyzing customer site measurement difficulties, we provide targeted solutions to these requirements, helping customers achieve safer, more efficient, and more economical integrated monitoring and intelligent control of temperature, pressure, flow, and liquid level.
Background
XX Company is a global leader in marine electrical equipment with a leading market share, deeply cultivating the marine electrical field for over 30 years, specializing in the R&D and manufacturing of marine high, medium, and low voltage switchgear, control systems, and automation management systems. In recent years, we have maintained close and continuous cooperation with this group, providing various automation monitoring and control solutions to the company. We deeply understand that the stable operation of ship generators is the "heart" of the entire vessel's power system, and the differential pressure monitoring of the seawater cooling system is the "lifeline" protecting this "heart." Relying on the group's leading technical strength and combined with our millisecond-level precision sensing capability, we work together to safeguard the safe operation of every generator, enabling ships to sail continuously, reliably, and fearlessly across global waters.
Pain Points
1. Sensor Corrosion Failure: Chloride ions in seawater are highly corrosive to ordinary pressure sensor diaphragms and wetted parts, easily causing sensor accuracy drift or even complete failure, resulting in measurement interruption.
2. High-Pressure Shock and Pulsation: Pressure shocks and periodic pulsations generated during seawater pump startup/shutdown and operating condition changes can easily damage sensor sensitive components, shortening equipment service life.
3. Lack of Real-Time Early Warning Mechanism: Traditional mechanical differential pressure switches only provide on/off alarm signals, unable to continuously monitor differential pressure change trends. It is difficult to detect insufficient cooling water flow risk in the early stages of abnormal differential pressure increase. Often, by the time the generator high temperature alarm sounds, the problem has already become serious.
4. High Maintenance Costs: Frequent sensor replacement, pressure tapping line cleaning, and unplanned shutdowns caused by inadequate generator cooling bring significant economic losses to ship operations.
Solutions

2. High Precision and Stability, Dynamic Reliability
- High Precision Guarantee: ±0.05% FS accuracy, providing reliable differential pressure data even under ship rolling and trimming conditions.
- Vibration Resistance Leader: Passed ship environmental adaptability and vibration testing, fearless against continuous vibration impact from generators and water pumps.
3. Corrosion Resistance and Durability, Fearless of the Deep Sea
- Ultra-Strong Corrosion Protection: Passed outdoor anti-corrosion grade WF2 testing, specifically designed for extreme environments with high salt spray, high humidity, and chemical corrosion.
- Fully Welded, Leak-Free: Fully sealed welding process eliminates leakage risks, ensuring long-term stable operation.
4. Continuous Monitoring and Intelligent Early Warning
Using 4-20mA+HART or RS485 communication, real-time differential pressure values are transmitted to the ship's Integrated Alarm System (IAS). Low limit, high limit, and rate-of-change alarms can be configured. When cooler filter blockage or seawater pump suction pressure drop occurs, the system can issue early warnings before generator high temperature occurs, reminding crew to promptly switch filters or adjust operating conditions.
5. Reduce Total Lifecycle Cost
Corrosion-resistant material design significantly extends sensor replacement cycles, reducing spare parts consumption and labor maintenance costs. Precision continuous differential pressure monitoring can issue early warnings before failures occur, avoiding generator high temperature shutdown and equipment damage, and minimizing unplanned voyage interruption losses.
