USi-safety Ultrasonic Sensor System

Whereas conventional ultrasonic sensors emit acoustic signals in the form of a radially symmetrical sound beam, in the USi-safety this takes the form of a strongly elliptical sound field. The opening angle of ± 17° / ± 5° creates an especially wide sensing range in one plane and a narrow sensing range in the other. This allows the sensor unit to be mounted in confined installation situations.

Sensors located on these films detect the transient acoustic signals produced by particle impacts. The arrival times of these signals at the sensor locations are used in a simple multilateration calculation to measure the impact coordinates on each film. Particle direction and speed are found using these impact coordinates and the known membrane separations. This ability to determine particle ...

Ultrasonic Sensor - an overview | ScienceDirect Topics

These sensors are directional, and provide a narrow beam detection range. Therefore, multiple sensors are needed to cover the width of a large vehicle. These sensors can be sensitive to particles in the air (dust, snow, and rain) and must be kept fairly clean to avoid any debris buildup on the face of the sensor. Improvements to these types of sensors are possible, and new systems may become ...

Introduction to Acoustic Emission – Integrity Diagnostics

Acoustic emission sensor is a device that transforms a local dynamic material displacement produced by a stress wave to an electrical signal. AE sensors are typically piezoelectric sensors with elements maid of special ceramic elements like lead zirconate titanate (PZT). These elements generate electric signals when mechanically strained.
