Choosing the Right Aerospace Sensor for Your Needs

As sensor technology become more advanced and innovators discover new ways to implement it into different areas of business and life, sensors will continue to integrate themselves into our everyday activities to help mitigate risks, maximize opportunities and transmit more information about the world around us. However, with the plethora of sensor technology on the market, it can be difficult to narrow down exactly what piece will fit your needs the best. In a mission-critical environment such as aerospace, it’s absolutely crucial you find the right one.

HSI Sensing has been meeting the unique challenges of aerospace sensors for more than 40 years, providing mission-critical solutions for everything from seat belt connections and shock sensing to fluid level monitoring and wing positioning. Our outstandingly reliable products can handle millions of cycles in applications and hermetically sealed switches ensure safety no matter where they are applied. In fact, our sensors are so precise that we can detect 1/100 of an inch of movement to individual degrees of rotation. Our AS9100 certification ensures that when we take on your aerospace project, you can be confident in our credentials. Some applications include extension/retraction in wing flaps; fuel vapor sensor; space station equipment pod position; pilot seat ejection and activates homing beacon.

Here are some of our top products in the aerospace industry to help get you started on your search:
