Non-contact vibration measurements made easy

Aerospace

Both turbine durability validation and the development of new NDT methods or a classic modal test will likewise benefit from vibration sensors that supply reliable results in a non-intrusive way. These can even be achieved in a vacuum, over long distances and under all temperature conditions. You can determine transfer functions, deflection shapes and strain distribution quickly and without any need for the time-consuming process of instrumentation.

Application examples include:

• Electronic Components Testing
• Model Validation
• Takeoff Stress Testing
• NDT
• Turbine Testing

Acoustics & ultrasonics

Vibrometers are indispensable tools for you when you’re designing loudspeakers and identifying disturbing membrane resonances.

Laser vibrometer measurements also prove beneficial in microphone, cell phone and hearing aid development.

Application examples include:

• Industrial ultrasonic methods
• Loudspeakers & musical instruments analysis
• Medical ultrasonic design & development
• Ultrasonic imaging
• Ultrasonic motors

Automotive

In the automotive industry, technical surfaces tip the scales when it comes to high-precision mechanics and their performance. The dimensional tolerance has a decisive influence on a product’s fuel and energy efficiency, eco-friendliness and durability.

From sealing surfaces, to the drivetrain and shock absorbers and to injection systems, there are a multitude of applications “being put to the test”. Absolute precision when contactlessly determining flatness, parallelism, form parameters, surface parameters, heights and steps is vitally important. And what should you use to ensure this? The surface measurement systems from Polytec, of course!

Application examples include:

• Drivetrain
• Sealing Surfaces
• Fuel Injection Systems
• Shock Absorbers
• Pass / Fail Analysis
• Tribology
