Promoted as low-cost components, the Virtu and Virtu18 ultrasonic sensors are now available with analog outputs. Both are dual-mount, barrel-style sensors with a sensing range from 50 mm to 508 mm and ...

Some photoelectric sensors, ultrasonic sensors, and rotary encoders generate a digital dc output called a push-pull signal. The external environment activates the sensor, which, in turn, closes a ...

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 ...

The 420B and 412B series of ultrasonic sensors from Leuze are available with an adjustable sound cone and as switching (HTU) or measuring (DMU) sensors allowing for flexible application. The sound ...

With its extended functional range and advanced temperature compensation, the T30UX sensor withstands hostile environments, providing superior ultrasonic sensing to solve even the toughest application ...

For years, ultrasonic sensors have been used in a wide range of applications including fish finders, parking sensors in cars and burglar alarms. In this article, we describe the characteristics of ...

Machines need sensors and transmitters to operate reliably and consistently. All it takes is a small drop in air pressure or a slight jam to cause a machine to crash; these sorts of problems can often ...

A new technology has been developed that enables cuffless non-invasive blood pressure monitoring by using ultrasonic to track ...

In-display fingerprint sensors have become commonplace in virtually all Android smartphones, for better or for worse, and five years later we’re finally seeing the ultrasonic variety widely used by ...
