Higher up in the sky with ASC accelerometers.

For many years, ASC has been a go-to partner for the most demanding test and measuring engineers in the aviation industry. This is a field imposing particularly high demands on measuring technology in general, particularly on sensors. At the end of the day the sensors must withstand particularly high temperatures and pressures, remain as light as possible and still deliver precise measuring results.

The innovative MEMS technology which we incorporate into our ASC sensors paves the way for reliable measurements in aviation R&D above all. Indeed, weight savings and a compact design allow measurements which would otherwise be barely possible. Our MF series sensors are also a first choice in the aerospace industry due to their low noise, high measuring accuracy and temperature stability.

Naturally, we remain at your disposal for assistance and, if desired, we will also develop individual sensor solutions to meet your specific challenges.

Did you know, for example, that ASC is also an authorised distributor for Honeywell Q-Flex® sensors for the German-speaking area of Europe?

In the aviation, we offer sensor solutions of unrivalled quality, with a scope including all of the following:

Structural analyses

When it comes to measuring vibration on all airplane components in particular, our IEPE  accelerometers  have proved their worth as reliable data sources. Here, the uniaxial ASC P101A15 sensor or the triaxial ASC P203A11 sensor are frequently used in environmental tests, to record the sinusoidal vibrations and impacts to which airplane components and subsystems are exposed. Moreover, IEPE accelerometers are also durable and hermetically sealed, catering for a wide dynamic range. The operating temperature range goes from -55°C to +125°C.

Modal tests on systems and subsystems generally involve deploying numerous high-performance acceleration sensors, which is a cost-driver when setting up the test. Here, our triaxial ASC IEPE P203A12 accelerometer offers an economic solution for such structural tests.

Flutter tests

So-called flutter-test applications show that our capacitive MEMS accelerometers thrive in this context. Here, the ASC 4421-MF series is the go-to choice as a lightweight option and excelling in terms of DC response behaviour within its low-frequency range of 0 Hz (DC) to 2.5 kHz.

The uniaxial accelerometers ASC 4211LN or ASC 4311LN and their exceptional dynamic performance when it comes to signal and noise are also ideal in this respect.

Flight tests

For flight tests our compact and lightweight ASC IMU 7.x.y [Link to the relevant datasheet] is deployed at measuring points where size is just as important as overall weight. For example, when determining the load of a range of structures. Further benefits of the ASC IMU 7.x.y include its low-noise response.

With the IMU 7.x.y we are offering a unique modular system, allowing us to generate customised configurations to meet individual requirements.

When it comes to measuring acceleration, there is a choice between the ASC LN series and ASC MF series [Link to the relevant datasheets] with a measuring range of ± 2g to ± 50g as well as a rate  range of ± 75 °/s to ± 900 °/s.

HUMS

For so-called Health-Usage-Monitoring-Systems (HUMS) in particular, our piezoelectric sensors, often used for monitoring applications, e.g. for gearboxes and rotors, really prove their worth. For example, the uniaxial IEPE ASC P401A15 accelerometer is a solution treasured by our aviation customers. The sensor weighs only 11g and has special fastening technology at the centre stud, offering mounting over a range of more than 150 degrees and thus optimal cable orientation.
