This Month Our Editors Search the Web to Bring You the Latest on Measuring Instruments

Every month, Control's editors take a specific product area, collect all the latest, significant tools we can find, and present them here to make your job easier. If you know of any tools and resources we didn't include, send them to [email protected] with "Resource" in the subject, and we'll add them to the website.

PICK YOUR PRESSURE SENSORToday's pressure sensors are called on to work in the harshest environments and with the most hostile and corrosive media, or sometimes just to take the simplest pressure readings. Selecting the right one for the right job is not necessarily an easy feat. Whether a particular pressure sensor is suitable for a specific application will depend in great part on the sensor's attributes, the environment it's being specified for and the job it's being asked to perform. To help sort your way through this maze, read "Choosing the Right Pressure Sensor—A Guide for Designers and Product Specifiers," a white paper from Honeywell Sensing and Control.
