Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

INTROTEK ® Non-Invasive PAD (Point-Air Detection) Sensor provides a reflective ultrasonic signal from a single contact point, making it the ideal air detection solution for fluid-handling cassette ...

A new ultrasonic fingerprint sensor measures 3-D image of your finger's surface and the tissue beneath it -- enhancing biometrics and information security for smartphones and other devices.

A future version of the iPhone could work better in the rain or the bath by detecting only touches of the display by the user, with Apple coming up with a way to tell the difference between finger ...

The sensor’s measurement range is 4 to 70 in. Accuracy is ±0.25% of full span at ambient temperature and pressure. Sensors feature a 10° beam angle, 12 to 28-Vdc supply voltage, and -in. NPT mounting.

SSI Technologies, a designer and manufacturer of ultrasonic level, pressure and magnetic sensors and monitoring systems, announced an SCR System DEF combination sensor to monitor urea level, ...

Small, fast ultrasound reflections require both high-speed and high-resolution digitizing as well as sufficiently deep memory to hold all the data. A company that manufactures ultrasonic ...

Sensortechnics introduces the new CLD series of non-invasive ultrasonic fluid monitoring sensors. These devices enable continuous bottom-up liquid level detection based on ultrasonic time-of-flight ...
