Sensors 102: Signal Conditioning

Today’s post is about what goes on between an actual detection device and the input of a control system. In many control applications you don’t need to think about what goes on inside of a device. The signal is converted

My Little Factory – April 2017

This post is the first in a series I am writing about a project I am working on, hence the “April 2017” designation. As most of my regular readers know, I have spent much of the past several years teaching

Sensors 101 – Control System Inputs

In today’s post I’m going to ask you to think of sensors in a different way. Most engineers who are specifying equipment think of sensors as discrete or analog devices, proxes or photoelectrics, flow or pressure sensors, thermocouples and the

Sensor Resources

When I got up this morning, I had fully intended to write a post on sensors and sensing techniques. I was even going to title it “Sensors 101”, similar to the series that I started on PLCs several years ago.

The Art of Cross-Referencing

There are many reasons you may want to replace a component in your automated system with something else. Some of the more common reasons might include: 1. The manufacturer doesn’t make it anymore. 2. I can’t get it as quickly

Web and Converting Terms

The picture above is from a project I worked on back in 2007. I haven’t worked on a web project since then, but I thought I’d share a section of my book that discusses some of the terms used in

Scales and Load Cells

Last week I described some of the vibratory equipment used in the system I was working on. I wrapped up most of the work on that system and have moved on to a different type of machine, but I thought

Magnetostrictive Sensors

Several of my topics in the past have dealt with gauging and measurement. Most of the systems I have worked on in the past used LVDTs, encoders, optical sensors or machine vision when it came to accurately measuring the physical

Anatomy of a Photoeye

One of my first projects when I was in engineering school was to make a coin counter that would detect the size of various coins as they rolled down a ramp and total up the denominations. The circuitry was fairly

Vision Guided Robots

This week was my first experience using vision and robots together. I have integrated many vision systems in the past and also done a number of robotic applications but this was my first time using vision to guide the robot.
