Viscosity, the resistance of a liquid to flow, is an important measurement requirement in industrial process control and OEM applications. Viscosity describes the retarding force that is proportional to the rate of deformation. This so-called shear rate has units of s1 and describes the cross-stream gradient of the flow speed.

If you're dealing with challenging environments, consider using ultrasonic sensors, with their longer and wider sensing ranges and immunity to color, ambient noise, and dust.

Ultrasonic detection of arcing, tracking, and corona in enclosed electrical cabinets helps reduce the potential for personal injury and equipment outage.

TR Electronic (www.trelectronic.com) has begun distribution, sales, and service of the complete range of Di-Soric position sensors in North America under an agreement reached between the companies in early January 2005.

Inspectors with the U.S. Bureau of Customs and Border Protection are beta testing a new, portable surveillance tool designed to thwart fraud and smuggling at our borders and ports.

When precision outweighs strength on your desirability scale, a piezoelectric motor might be just what you need.

Acoustic wave sensors are extremely versatile devices that are just beginning to realize their commercial potential. This tutorial addresses acoustic wave sensor physics and materials, and the various types of acoustic wave sensors and their industrial applications.

Built in silicon with advanced MEMS technology, new ultrasonic sensors offer improvements in performance and cost and enable a wider range of applications.

An understanding of radiation patterns and the target's effect on echoes is essential to evaluating candidate sensors in terms of frequency variations, accuracy and resolution, target range, effective beam angle, and the influence of ambient temperature variations on sensor performance.

The first step toward identifying the right proximity sensor for your application is to understand the fundamental ultrasonic properties of the transmission medium and the way they influence the measurement and system operation.
