Reliable pressure sensor for remote underwater vehicles. Accurate depth measurement - Application for remotely operated underwater vehicles (ROVs).
Under the sea surface, it is even more important to maintain continuous position information to avoid going missing in the deep sea. Remotely operated underwater vehicles (ROVs) use multiple underwater navigation sensors, including depth sensors, for navigation. A depth sensor measures the surrounding water pressure and calculates the distance to the water surface. Depth underwater is typically determined from pressure. Converting pressure to depth (the water column above the measurement point) is not particularly difficult. The issue is accuracy. We received the following comment from a user of Keller products: "The performance is the same today as it was on the day it was shipped from the Swiss factory. Since I started using Keller's pressure sensors, the measurement accuracy has dramatically improved. I was honestly surprised by how sensitive they are. They respond not only underwater but also when moved up and down in the air. The RS485 digital output is very convenient, and above all, the stability of the sensors is outstanding. I am a big fan of Keller." What kind of sensors are being used, and why is Keller able to achieve excellent stability and accuracy even in harsh underwater environments?
