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

The "TU Vienna Space Team," operated by students of the Vienna University of Technology, is working on the rocket project "Lamarr," which focuses on launching a liquid rocket using ethanol and liquid oxygen as propellants. The "Lamarr" rocket is equipped with pressure sensors from KELLER Pressure, specifically the PAA-23SY, PAA-21Y, and PD-39X series. These high-precision pressure sensors play a crucial role in ensuring the smooth progress of the mission. The pressure sensors measure the pressure in the pressurized tanks, fuel tanks, and combustion chamber of the rocket engine. The project team uses the measurement data supplied by the sensors to monitor and control various elements essential for stable flight. Pressure measurement technology in the aerospace field complies with the highest safety standards and has high demands for functionality. Therefore, in this field, highly specialized pressure measurement systems tailored to each customer are produced. For the "Lamarr" project, the KELLER Pressure standard specification piezoresistive pressure transmitters were selected. For more details, please follow the link below!

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.
