Pressure sensor for bipropellant rockets

KELLER Pressure Japan KELLER Pressure Japan 日本支社
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!

Keller Company Ultra High-Speed Pressure Sensor M5HB

Ideal for measuring pulsations and unsteady behavior with a bandwidth of 50 kHz, temperature-resistant up to 180°C, built-in amplifier (0-10V output) high-precision pressure sensor.

The ultra-high-speed pressure sensor M5HB can measure not only static pressure but also pressure changes within a bandwidth of 0 to 50 kHz. This is achieved by the digital circuit continuously adjusting the analog signal in real-time, with an output of 0 to 10V. The compact sensor head with M5 fine thread can be used at temperatures up to 180°C. It has a pressure resistance of up to five times the measurement range and is an excellent model for vibration resistance. 【Features】 - Temperature resistance of the sensor head: 180°C - Output is an analog signal of 0 to 10V (with built-in amplifier) - Wide temperature compensation range: -20 to 125°C or -40 to 180°C - Bandwidth of 50kHz, ideal for measuring pulsations and unsteady behavior - Resistant to impacts and vibrations - Compact design, pressure connection is M5×0.5 fine thread
