The shipping industry places high demands on measurement technology. Pressure sensors play a crucial role in monitoring and controlling various systems onboard ships. They help ensure safety, improve efficiency, and minimize environmental impact.
Monitoring Dry and Liquid Loads
Accurate monitoring of pressure in storage tanks is essential during cargo transportation by sea. Particularly for liquid loads such as gasoline, oil, or marine diesel, reliable pressure measurement is required to prevent leaks and ensure safety. Therefore, pressure sensors must be robust and durable to withstand the challenging conditions at sea.
Freshwater and Wastewater Tanks
On ships, freshwater is either stored in dedicated tanks or obtained from seawater. The collection, treatment, and disposal of wastewater require precise monitoring with suitable sensors. Since wastewater is often contaminated with harmful substances like oils or cleaning agents, sensors must be corrosion-resistant and reliable to ensure efficient system monitoring.
Ballast Tanks
Ballast tanks are vital for the stability of ships. Filling or emptying these tanks with seawater allows the ship's weight and balance to be adjusted. As these tanks are filled with saltwater, both the tank materials and the sensors used must be corrosion-resistant. Additionally, high reliability and durability are necessary because sensors are difficult to access during operation and must function without manual maintenance.
Specific Requirements for Sensors
The shipping industry has experienced significant innovations in recent years that also influence sensor requirements. While stainless steel was once considered sufficient, it has been shown that it can corrode when in contact with seawater and temperatures above 21°C. Therefore, titanium is increasingly used today due to its extreme stability and robustness. STS recognized this need early on and uses titanium as a standard material for various pressure transmitters and submersible probes, ensuring reliable operation even under the harshest conditions.
Conclusion
Pressure measurement technology is an indispensable part of modern the shipping industry. It enables safe and efficient monitoring of cargo, water and wastewater systems, and ballast tanks. Through the use of durable materials like titanium and continuous advancements in sensor technology, STS ensures that its products meet the high demands of the industry.
