Sensor Technology Explained

Intrinsically safe IS sensors are designed to operate safely in hazardous areas where there is a risk of explosion IS sensors limit the amount of electrical and thermal energy that can be released in the event of a fault to

A multiturn rotary encoder is a sensor that measures the angle of rotation of a shaft as well as the number of complete revolutions that the shaft has made This is in contrast to a single turn encoder which only

Recently obtaining the Inductosyn and components for maintenance has become more difficult For decades the Inductosyn from Farrand Controls Ruhle Companies sat near the top of the rotary sensor hierarchy Providing sub 2 arcsec 0 5 mdeg accuracies it combined

There are several key terms that are critical to specifying the optimal position sensor for a given application This application note defines these key terms and how they relate to the sensor s role in the overall system performance It

The Wiegand effect was discovered almost fifty years ago and has been used successfully in several specialized applications However its full potential for energy harvesting and signal generation has received only limited recognition With recent enhancements to the energy output

With the increasing sophistication of electronic controls for mechanical systems there is more demand for durable accurate and easy to use displacement sensors As automation becomes more common there is also an increasing sensitivity to price Customers also want sensors

Despite their perceived simplicity potentiometers can still be an appropriate option in today s ever complicated automation industry Fundamentally a variable resistor modern potentiometers also offer more traditional outputs such as voltage and current which are common to more expensive

Rotary encoders are used in a variety of applications to provide feedback on position speed direction or angle There are several different encoder types 8230

Intrinsically safe IS sensors are unable to produce a spark strong enough to cause ignition Learn how this is accomplished and design considerations when using IS sensors
