High-g is an acceleration value larger than 105 g. For the requirements of detecting high-g, people pay more and more attention to the reliability of an accelerometer. In this paper, the design and manufacture of high-g micro array acceleration sensor are researched to improve the reliability of the accelerometer. Owing to the superiority of MEMS manufacturing, in one processing, multiple micro-acceleration sensors with the same function can be integrated in one chip. According to the method of the array layout of multiple micro-acceleration sensors on a two-dimensional plane, the layout is ascertained by using multiple non-linear regression and orthogonal experimental design. Multiple micro-acceleration sensors lay reasonably to improve the reliability of the high-g micro array acceleration sensor. The linked line of sensor system, which is manufactured according to these parameters, remains intact by the impact of 1.22 × 105 g. Owing to the optimised design and manufacture, the reliability of the acceleration is increased to 0.9906, which meets the requirements of the application.

The benefits of a Force-Balanced Sensor
Your projectneeds the precision to monitor movement as fine as 1 µG or µradian, but there will also be a lot surrounding noise and vibration that you don’t want to interfere with your readings. If you’re working on somethinglike this, a sensor with force-balanced technology is the answer and here is why. Benefits of Force-Balanced Sensors Force-balanced sensors have a strong dynamic response (as much at 200 Hz for some models) and diverse measuring ranges, up to +/-90° for inclinomet...
Forget big data! Collect the right data
The term big data is everywhere nowadays, but what does it actually mean? According to a definition provided by Google, big data is ‘extremely large data sets that may be analysed computationally to reveal patterns, trends, and associations.’ Sounds great, right? In theory, yes. Through big data, businesses can have a greater overview of their operations than ever before, allowing them to improve efficiency and improve their service. However, in practice achieving this is rarely the case. The issue...
Opening the envelope on bearing vibration
A sophisticated signal processing technique can help to pinpoint bearing failure at an early stage. Chris Hansford, Managing Director at Hansford Sensors, explains. Experienced operators can often tell if a machine is not working properly, on the basis that is does not ‘sound right’. The same principle can be applied – using modern electronics – to identify the exact cause of the problem. Sensitive accelerometers can detect and analyse the vibrations from industrial equipment, highlighting...
How to ensure successful acceleration enveloping
Following the interest shown in our recent blog discussing acceleration enveloping, the sophisticated signal processing technique that helps to pinpoint bearing failure at an early stage, we thought it would be a good idea to explain how to successfully implement it. There are several factors that ensure you can achieve the best possible results, these include: Select your accelerometers correctly! Excuse the dramatic exclamation mark preceding this sentence, but the selection of accelerometers is the difference...
Airbus Helicopters: Monitoring gearboxes with HUMS accelerometers case study
Airbus Helicopters needed highly robust, flight-certified accelerometers for permanent monitoring of gearboxes to be quickly designed and delivered.ChallengeFor helicopters, one of the most dangerous possible scenarios – worse than engine failure – is gearbox failure. Quality vibration monitoring is needed to ensure gearbox health and predict failures, while absolute reliability is vital to eliminate false alerts that would lead to ditching. Under tough conditions, this requires robust resistance to...
