Aerospace applications
Aerospace testing brings some of the toughest measurement challenges in engineering. Engine and airframe testing, launch qualification and in-orbit missions all need sensors that are light, accurate and dependable under stress.
DJB works with aerospace manufacturers, research organisations and satellite builders worldwide. Our miniature accelerometers, low-outgassing cables and specialist mounting solutions are built for these environments.
Testing for extreme operating conditions
Satellites and flight systems must survive:
- Extreme temperature swings
- High vibration and acoustic loads during launch
- Ultra-high vacuum
- Radiation exposure
- Mechanical shock and structural stress
Ground testing proves a system can cope before it flies. That only works if the sensors measuring it are just as robust, and don't change the behaviour of the structure they're fixed to.
Space testing range
Our space range is small, light and built for vacuum, from sensors on a single circuit board to full satellite assemblies. Most are hermetically sealed, so they can stay on board for launch.
Precision vibration sensors for demanding aerospace testing and monitoring applications. Designed for accurate measurement across structural, acoustic and high-temperature environments.
Signal conditioning and measurement instrumentation designed to preserve data accuracy from sensor through to acquisition and analysis systems.
Low-noise cables, connectors and mounting accessories engineered to maintain signal integrity in harsh testing and operational environments.
Planning satellite qualification or vacuum testing? Come and see our miniature, hermetically sealed accelerometers and low-outgassing cables up close, and talk through your test set-up with our engineers. Prosig will be on the stand too, covering data acquisition and analysis.
Built to meet your exact application requirements and extend cable life
From ultra-flexible low-noise cables to armoured and miniature assemblies, DJB designs and manufactures bespoke cable solutions tailored to your installation and testing environment. Our inspection and repair service also restores damaged or worn assemblies, helping reduce replacement costs while ensuring continued measurement reliability.

Low-outgassing connectors and heat-shrink stress relief, with cable lengths and assemblies made to order.
In-flight health monitoring
DJB sensors also monitor engines and gearboxes in flight, where temperatures and stresses are high. Many are customised for specific aircraft platforms. If you need a sensor built around your application, talk to our engineers.
Low outgassing for space and vacuum testing
In a vacuum, materials can release trapped gases that contaminate optics and sensors. Everything installed on a satellite must meet strict low-outgassing requirements.
- All materials in DJB accelerometers meet low-outgassing requirements as standard.
- Around 90% of our cables are standardised to suit low-outgassing requirements.
- For space builds, connector stress relief uses a special low-outgassing heat shrink.
- Cable lengths and assemblies are made to suit your test setup.
Customers around the world have tested and verified that these materials meet the standard.
Tested on Earth, flown in space
Our A/124 miniature IEPE accelerometers are installed in satellites during the build, in both top- and side-entry versions, along with their cables and connectors. During environmental and structural testing, they monitor the satellite, giving the critical measurements that show a very expensive asset is fit for flight.
Because they're part of the build, they then launch with it, never to be seen again.
