When reviewing or approaching an application, we all know that the correct sensor technology plays a key role in reliable detection of production parts or even machine positioning. In many cases, application engineers choose photoelectric sensors as their go-to solution, as … Continue reading
In my previous posts (Ultrasonic Sensors with Analog Output, Error-proofing in Window Mode, and The Other Retro-Reflective Sensors) we covered the Ultrasonic sensor modes and how they benefit in many different types of applications. It is also important to understand … Continue reading
Many times in an application we need more than a simple discrete on/off output. For a more accurate detection mode we can utilize analog outputs to monitor position, height, fill-levels and part presence typically found in object detection assemblies. When … Continue reading
In my previous post, I talked about Ultrasonic Sensors utilizing reflected mode. Window mode is an extension of the reflective mode setting. When the sensor is set up in window mode the sensor is only activated when the object target is located … Continue reading
Most of the time when we think of Retro-Reflective sensors the first thing that comes to mind is a photoelectric sensor. Photoelectric offerings use a reflector to reflect light from the internally mounted emitter and receiver. Retro photoelectric sensors come … Continue reading
Liquid measurement can be a demanding application therefore selecting the most effective sensor technology is imperative. Ultrasonic sensors are the ideal solution for distance measurement or position detection of granules, fluids and powders. They measure fill levels, heights and sag … Continue reading
When looking at Ultrasonic Sensor Technology one of the most problematic areas of application is false positive outputs due to a large operating angle. It is not uncommon to have an Ultrasonic Sensor in an application where the sensor has … Continue reading
When an application calls for an Ultrasonic sensor it is very important to understand the principles of operation. The most important question in sensor selection… what is the operating distance needed? How far away can I be from the target? … Continue reading
