KELLER Pressure Japan Company Profile

A student team from Delft, Netherlands, is developing a bipropellant rocket powered by hydrogen peroxide. In the search for optimal components, KELLER Pressure became involved. Rockets using hydrogen peroxide as a propellant are not new. However, this fuel method has hardly been used since World War II and the early days of space development. "We wanted to recreate this fuel at a student level, in a low-cost and from-scratch development approach. Initially, the goal was simply to 'get it to fly,' but as we progressed, we evolved to the stage of designing a 'flyable vehicle.'" Two types of KELLER Pressure sensors are being used (M5HB for measuring pressure inside the engine and 7LC for measuring the pressure in the hydrogen peroxide and ethanol tanks). These sensors are lightweight, compact, and have excellent material compatibility. Additionally, the fact that the technical specifications are openly published has been appreciated. All necessary information can be checked on the website, allowing for compatibility assessments without needing to contact the sales representative. Communication after the decision to use the products was also smooth. For more details, please check the related links below!

Many applications today require not only accurate measurements but also fast measurements. In this context, the dynamic behavior of sensors becomes particularly important in addition to measurement accuracy. While the limiting frequency of electronic circuits, sampling rates, or similar parameters are often recognized as decisive factors, this is actually just one aspect, and it is necessary to consider the entire sensor system. How much speed is required from the sensor? What are the factors that truly affect the dynamic characteristics of the sensor? I will explain why not only electronic circuits but the entire sensor design is important. I will introduce typical application examples that require millisecond-level speeds, provide findings from test results, and assist you in selecting the optimal sensor according to your needs.

It is extremely important to detect leaks as early as possible during the construction phase. In particular, when moisture penetrates walls, floors, and ceilings, it can cause significant damage, much of which is due to leaks from water pipes. Traditional methods such as manual pressure testing and partial visual inspections have their limitations. What is needed is continuous and intelligent monitoring. AWOSSA provides a powerful and autonomous solution for the construction industry through digital leak monitoring. This system detects leaks early and automatically sends alerts, allowing for prevention before costly damages occur. Key features of the system: - Continuous recording and analysis of pressure and temperature data - Real-time leak detection at construction sites - Automatic notifications via email or SMS when set values are exceeded - Intuitive web interface for settings and data analysis How the system works: The sensors continuously monitor throughout the construction period, reliably detecting even slight changes in pressure or temperature. If an anomaly is detected, the responsible personnel are notified immediately. With a built-in battery, it can operate autonomously, and once the system is activated, monitoring begins automatically.
