KELLER Pressure Japan Company Profile

The Academic Space Initiative Switzerland (ARIS), in collaboration with the Swiss Federal Institute of Aquatic Science and Technology, has established a mission: multiple autonomous underwater robots will simultaneously dive into a lake to collect measurement data at depths ranging from 5 to 30 meters. The goal is to visualize water quality in three dimensions. The greatest advantage of a swarm is its simultaneity. Instead of measuring sequentially at individual points, forming a densely synchronized measurement area allows for the detection of anomalies, identification of hotspots, and narrowing down of pollution sources. To achieve this, each robot must constantly and accurately understand the water depth. Why "water depth"? GPS cannot be used underwater. Since underwater robots cannot verify their location as they can on land, pressure becomes the most important indicator for determining position and orientation. In this project, the KELLER Pressure sensor PAA-9LX has been adopted. These sensors are installed within the waterproof housing of the robots and measure the surrounding water pressure. Water depth is calculated in real-time from this pressure data. For more details, please refer to the related links below!

KELLER Pressure offers pressure sensors with models that allow for adjustable pressure ranges. There is no need to have separate sensors for each pressure range, as one unit can comprehensively cover all ranges. This significantly contributes to cost reduction. Additionally, there is no need to worry about delivery times for additional orders. The compatible models include OEM types, general-purpose types, high-precision types, and explosion-proof types, among others. We also conduct demonstrations on how to change the pressure range, so please feel free to contact us if you would like more details. Series 23SX (General-purpose type) Series 33X (High-precision type) Series 10LX, 20SX (OEM type) Series 41X (Low-pressure type) Differential pressure type Explosion-proof type
