Sensors! The Eyes and Ears of Automation.

Sensors are a vital component used in any type of automation. Sensors allow us to know when an object is present, in place, missing, or maybe even defective. Other sensors may tell us even more about what is going on such as how close or far away an object is or how big or small something is when it is changing in size or shape.

Whether you are automating machine control and need to know if a part is in place, automating a conveyor and need to know if a box is present in a certain location or you are winding up material on a spool and need to know when it reaches a certain size in diameter, sensors are usually required in every piece of automated machinery or system regardless of the intelligence of the control being used.

AutomationDirect has thousands of sensors in stock and ready to ship the same day you place your order. Some places our customers have used our sensors are in traditional machine control, industrial automation, water/wastewater, food & beverage applications, and in home automation projects (Note that this is not an exhaustive list). Check out the articles below for more on industrial sensors, how they can be used, and what they can provide.

Basic Sensors – PLC Fundamentals

For a PLC to monitor and in turn control its application variables, there must be a way for it to sense its surroundings. In today’s industrial realm, there are a huge variety of electrical sensors that provide the input data (position, distance, level, flow, etc.) that control systems need. Read More –>
