Both washdown and hygienic design are common terms used in the food and beverage industry, and are increasingly being used in the packaging industry. These terms are used in different scenarios and easily confused with each other. What exactly are … Continue reading
Continuous measurements on industrial machines or the materials that these machines are making, moving, or processing can be categorized into two main types of sensors: position measurement sensors, and distance measurement sensors. It’s a somewhat subtle distinction, but one that … Continue reading
In the past, color sensors emitted light using red, green and blue LEDs’. The sensors were then able to distinguish colors using the RGB components of the reflected light back to the sensor’s receiver. As technology has progressed true color … Continue reading
Initially I started to write this blog to compare photoelectric sensors to ultrasonic sensors for level detection. This came to mind after traveling around and visiting customers that had some very interesting applications. However, as I started to shed some … Continue reading
Some photoelectric applications require not only knowing if the object is present or not but exactly where the object is while providing a continuous or dynamic value representative of the objects location. For instance, if a robot is stacking a … Continue reading
The foundation of a photoelectric sensor is light! Without the light you have a housing with some electronics in it that makes an interesting object to leave on your desk as a conversation starter. Is all light the same? Does … Continue reading
Photoelectric sensors are used in a wide variety of applications that you encounter every day. They are offered in numerous housing styles that provide long distance non-contact detection of many different types of objects or targets. Being used in such … Continue reading
Bubble or air-in-line detection is a common lab automation application. In these types of applications it’s important to know whether or not liquid is flowing through a line to ensure safe and proper function in liquid-handling processes. As these processes … Continue reading
