Speedier, More Accurate Testing of Automotive Sensors Is Here

Combining stimulus test cells with automated handlers to create a multi-test module.


The amount of electronic content in automobiles continues to grow at a brisk pace, and sensors represent a significant percentage of cars’ electronics. MarketsandMarkets estimates that the automotive sensors market alone will reach US$36.42 billion in value by 2023, at a compound annual growth rate (CAGR) of 6.7 percent between 2017 and 2023.

Sensors in cars are used to monitor and control a host of functions. Pressure sensors are growing at nearly the same rate as the overall automotive sensor market. Technavio reports that the global automotive pressure sensors market is anticipated to post a CAGR of more than 6% between 2017 and 2021. This is due to growing demand for fuel efficiency, safety, and reduced emissions. Many different types of pressure sensors exist, with varying requirements as to the level of pressure they require.

One key subset of pressure sensors – exhaust and side and center airbag sensors – requires very low pressure. The thresholds at which they should activate and deploy are well below 1 megapascal (MPa), and as low as 600 kilopascal (0.6MPa) because their ability to deploy when needed is absolutely critical to protect passengers’ health and safety. Therefore, it’s imperative that they be accurately tested to ensure their functionality prior to purchase and use of the vehicle into which they’re integrated.
