Space Tech Expo Europe, the main meeting-place for representatives of the European space industry, will open its doors from 24 to 26 October in Bremen, Germany. This international exposition is also a fixed event on Kistler’s trade fair programme: the company’s experts will be on hand at stand A51 in hall 5 to show visitors measurement technology capabilities and products for challenging space applications.
Sensors play a key role in space payload, propulsion and subsystem testing and provide valuable measurements to support quality, safety and reliability of space systems and subsystems. In this sector, products have to meet very demanding requirements due to extreme conditions that include wide temperature ranges, pressure fluctuations, high shock and vibration levels. At the same time, the measurement equipment often has to be lightweight as well as rugged and durable. Kistler offers the right force, vibration and pressure sensors for virtually every application.
Manuel Blattner, Head of Kistler’s Strategic Business Field Test & Measurement, explains: “As the highlight of our presence at Space Tech Expo Europe, we shall be presenting product solutions for selected space applications to the show visitors. At our fair stand, attendees can see exhibits such as a rocket engine test bench with built-in pressure, force and acceleration sensors, as well as the new piezoelectric 6-component force/torque link, Type 9306A.”
Entire satellites and their subsystems could sustain severe damage due to overloads during vibration tests. Force Limited Vibration Testing is used to prevent this from happening. This testing uses 3-component force sensors at the shaker to payload interface to monitor the introduced forces. Kistler will exhibit a useful product for this application at the Space Tech Expo: preloaded 3-component piezoelectric force sensors connected to cutting-edge signal conditioning and data acquisition systems. Installed between two mounting flanges, these preloaded sensors can measure compression and tensile forces in every direction. Accurate results are ensured thanks to very high rigidity allowing for a high natural frequency as well as a very low crosstalk.
Signals are measured and conditioned with the LabAmp 5167A, Kistler’s first multi-channel quasistatic and dynamic charge amplifier with analogue output and integrated data acquisition. The benefit: a scalable and configurable high-performance signal conditioner and data acquisition system offering channel synchronisations, signal filtering, virtual channels and convenient evaluation of individual force signals. Integrated data acquisition simplifies the measuring chain and provides added flexibility.
Optimal results – even under extreme stress
Rockets are exposed to very high stresses, especially during launch. To prevent malfunctions during operation, rocket components – and especially rocket engines – undergo extensive testing and inspection during the testing phase. Kistler is also showcasing the Type 6021A high-temperature pressure sensor at the Space Tech Expo Europe. This uncooled pressure sensor is suitable for application temperatures of up to 700degC and provides is high-resolution pressure measurements to understand the combustion processes and related instabilities. For this purpose, the pressure sensor is ground-isolated and is connected to a differential charge amplifier providing low noise and EMI immunity to support accurate measurements. Tradeshow visitors will also have the chance to appreciate the benefits of Kistler’s Type 5181A differential charge amplifier for high temperature test requirements.
Yet another highlight to be unveiled by Kistler at the Space Tech Expo Europe is the first piezoelectric 6-component force/torque link, Type 9306A. This sensor can deliver precise and direct measurements of three forces and three torques without calculation: an excellent choice for measurements in wind tunnels. Kistler charge amplifiers provide users with the ability of adjusting the torque and force measuring ranges independently for each axis. Thanks to the piezoelectric measurement principle and 9306A performance very small torques and forces can be easily measured with high resolution.
