Linear Position Sensors - Control is Only as Precise as the Feedback

Linear Position Sensors - Control is Only as Precise as the Feedback

Linear position sensors are used in electrical and fluid-actuated motion devices. They allow extremely precise position, velocity, and acceleration control, and provide feedback to ensure product quality and tolerance compliance.


Info Byte: What’s the Deal With Debouncing Switches?

Info Byte: What’s the Deal With Debouncing Switches?

Before digital control systems, responses were fairly slow. Push a button, and a motor contactor engaged. These days, the speed of computers introduces some new challenges but brings solutions as well.


How IIoT is Transforming Predictive Maintenance

How IIoT is Transforming Predictive Maintenance

The objective of predictive maintenance is to foresee potential machine failure with the help of machine learning algorithms provided with vast quantities of data.


Combating That Killer of Industrial Pneumatic Systems - Water

Combating That Killer of Industrial Pneumatic Systems - Water

Moisture inside industrial pneumatic systems is a major cause for concern, and if the air is not filtered or dried properly, it can lead to serious failures.


Troubleshooting for PLC Modules and I/O Devices

Troubleshooting for PLC Modules and I/O Devices

Failures of I/O systems are a common source of headache for control engineers. Troubleshooting those devices that have polarized connections (source vs sink, and NPN vs PNP) is a technique worth refining.


My First Experience Programming a Collaborative Robot

My First Experience Programming a Collaborative Robot

We've read about the capabilities of collaborative robots, but often, one question still remains - how do you program a cobot? Last week, I got a chance to get my hands on a cobot for the first time.


SPC Pillar: Design of Experiments (DoE)

SPC Pillar: Design of Experiments (DoE)

The fourth pillar of effective statistical process control (SPC) is the use of designed experiments used to learn as much as possible from a limited number of experiments, yet remain statistically relevant enough to be useful.


Understanding the Basics of Pulse Width Modulation (PWM)

Understanding the Basics of Pulse Width Modulation (PWM)

Power delivered to devices can be changed by raising or lowering the voltage and current. But this method does not always produce intended results. Pulse width modulation (or PWM) can be used to better control variable loads.


Application Considerations for pH Sensors

Application Considerations for pH Sensors

Measuring pH is a critical task of many chemical processes and systems. Learn the definition of pH, the measurement tools, and the calibration steps for proper operation and care of these meters.


SPC Pillar: Continual Improvement Process (CIP)

SPC Pillar: Continual Improvement Process (CIP)

Statistical process control (SPC) allows for continual improvement process (CIP), a method of optimizing a process driven by data and statistical methods.


SPC Pillar: Using Control Charts

SPC Pillar: Using Control Charts

Learn how control charts are used in statistical process control (SPC) to show how a process changes with time as compared to past measurements, providing reliable visualizations for data-driven decisions.


What Is a PLC? An Introduction to Programmable Logic Controllers

What Is a PLC? An Introduction to Programmable Logic Controllers

What is a PLC? This article will lay out a succinct definition of a programmable logic controller and explain its basic components.


Info Byte: Definition of Pressure and Flow in Fluid Systems

Info Byte: Definition of Pressure and Flow in Fluid Systems

Pressure and flow rate are terms used in all areas of hydraulic and pneumatic systems. Learn the definition and science of these terms, and the reason they are so important within industry.


SPC Pillar: Data Collection

SPC Pillar: Data Collection

Statistical process control (SPC) is meaningless without the proper collection and analysis of data. For some process parameters, this is a simple task. But not every part of a process is driven by simple, quantitative parameters.
