Sensors for the aviation industry
The aviation industry requires high quality, safety and absolute accuracy for its critical applications. At Althen you will find customized solutions for gyroscopes, flow sensors, pressure and acceleration sensors for all your requirements. We supply various sensors that meet the high demands of the aerospace industry.
Gyroscopes (angular velocity sensors)
Where heavy, maintenance-prone mechanical gyroscopes were previously used, our MEMS gyroscope sensors and air data systems now offer a compact, maintenance-free and highly accurate alternative. Thanks to a unique silicone ring technology with no moving parts, in a hermetically sealed ceramic housing, these very small sensors deliver stable performance under a variety of conditions, with high resistance to moisture and temperature.
Air Data Probes
In addition to MEMS gyroscopes, air data probes are also used to measure air data with high accuracy. They provide real-time information on the position of an aircraft or UAV relative to the apparent wind. The probes are heatable, which makes them suitable for use at high altitudes, for example in unmanned aerial vehicles. Over 90% of our air pressure probes are custom developed.
Accelerometer
An accelerometer measures forces such as gravity, motion and vibration, and helps systems better interpret their environment. Althen offers a wide range of accelerometers.
Inertial navigation systems
IMUs (Inertial Measurement Units) are essential in aerospace systems, providing important data on orientation, acceleration and gravity. Our IMUs combine high accuracy, low noise and robust design, making them ideal for navigation, guidance and stabilization in aircraft, satellites and UAVs.
Aerospace applications
Test benches and test setups
Test equipment for hydraulic and pneumatic systems must be compact, lightweight and highly accurate. Space applications often require special threads, as well as a wide measuring range and reliable performance. Althen supplies pressure sensors that perfectly match these requirements.
Fuel Systems
The implementation of power transmission systems often requires customized sensor assemblies. These must be able, even under extreme conditions, to perform temperature and pressure measurements accurately and reliably. Althen supplies sensors suitable for safety-critical applications in aircraft construction, where high demands are placed on accuracy and reliability.
Spare parts and retrofitting
Replacement of discontinued sensors? We think in terms of solutions. Althen supplies suitable sensors, adapters, cables and housings customized to ensure that your aircraft or helicopter remains reliable and operational for a long time even if spare parts are no longer available through the manufacturer.

This is how to choose the right sensor
The choice requires careful consideration of several factors to ensure optimal performance, reliability and safety. Engineers consider the following aspects, among others:
- Accuracy and precision Aviation systems place high demands on measurement accuracy and reproducibility. Choose sensors with proven precision and low measurement uncertainty to meet the industry's stringent performance requirements.
- Reliability and durability Aerospace environments are often extreme, with exposure to high temperatures, vibration, shock and radiation. Choose sensors with rugged designs that can withstand these conditions to prevent failures and ensure long-term reliability.
- Temperature and pressure ratings Ensure compatibility with operating conditions by selecting sensors based on their temperature and pressure resistance. Choose models that continue to perform within the specified range without loss of accuracy or reliability.
- Size, Weight and Power (SWaP) Space and weight constraints play a starring role in the development of space systems where every gram and centimeter counts. Choose compact, lightweight and power-efficient sensors.
- Response time and frequency range Ensure timely and accurate data acquisition by selecting sensors with fast response time and wide frequency range. This is especially essential in dynamic space environments, where capturing transient events and high-frequency signals is critical.
- Calibration and maintenance Choose sensors that are easy to calibrate and maintain, with accessible procedures and long-term stability. Regular calibration is important to ensure long-term accuracy and reliability.
- Compatibility and integration Choose sensors that integrate easily with existing aviation systems and interfaces. Standard communication protocols and compatible interface options ensure smooth integration and optimal interoperability within the system architecture.
- Cost and life-cycle considerations Consider the total cost of ownership, from acquisition to maintenance and service life. Choose sensors that combine optimal performance and reliability with cost efficiency over the full life cycle of the space system.
A focused consideration of these parameters allows engineers to select sensors that are technically compatible, operate stably and meet system requirements within aerospace applications.
