Ultrasonic sensor detects multiple
frequencies

Ultrasonic acoustic sensor uses the latest MEMS technology to provide a robust mechanical device that performs over a wide environmental range.

Knowles Acoustics has developed an ultrasonic acoustic sensor (UAS) for use as a component to detect/receive ultrasonic sound in air The sensor uses the latest technology in MEMS (microelectromechanical systems) to provide a robust mechanical acoustic sensor which performs over a wide environmental range

Sampling and low volume production is being offered now with mass production beginning in Q2 2007.

Pricing is comparable to current piezo-ultrasonic receiving sensors on the market.

Compared with conventional ultrasonic sensors that have a narrow frequency band of detection, the Knowles sensor is ideal for capturing a wide frequency range applicable to a variety of ultrasonic applications: ultrasonic range detection, condition monitoring, fault detection, level sensing and position sensing.

The sensor can be used to monitor and detect frequencies from 10 to 65kHz with minimal attenuation across the frequency range.

"As the recognised leader in acoustics for a variety of consumer, medical, military and industrial applications, we find that our components are continually being specified into alternative applications from their initial intent".

"Our new ultrasonic sensor is a receiving element that enables the ability to detect multiple frequencies within a single sensing element".

"Thus, reducing or eliminating the guesswork for customer on identifying the appropriate sensor for the frequency needing to be detected or monitored", says Angelo Assimakopoulos, Director of New Business Development for Knowles Acoustics.

The sensor's miniaturised surface mountable package design also makes it adaptable for use in many finished goods as well as industrial products. Request a free brochure from Knowles Acoustics ...
