In my previous blog post we covered the Anatomy of a High Pressure Proximity Sensor. That post covered the different mechanical housing designs and special properties that go into high pressure sensor products with discrete outputs. That is great information … Continue reading
Going about our hectic daily lives, we tend to just take the modern cycle of innovation for granted. But when we stop to think about it, the changes we have seen in the products we buy are astonishing. This is … Continue reading
Some industrial applications will require a sensor with special properties. This type of sensor offering is needed especially when pressure comes to play. In a wide range of hydraulic cylinder and valve applications high pressure sensors are exposed to hostile … Continue reading
In one of my previous post we covered “How do I wire my 3-wire sensors“. This topic has had a lot of interest so I thought to myself, this would be a great opportunity to add to that subject and … Continue reading
When the topic of welding comes up we know that our application is going to be more challenging for sensor selection. Today’s weld cells typically found in tier 1 and tier 2 automotive plants are known to have hostile environments … Continue reading
In my last post (We Don’t Make Axes Out of Bronze Anymore) we discussed the evolution of technologies which brought up the question, can a prox always replace a limit switch? Not always. Note that most proxes cannot directly switch … Continue reading
Every technology commonly in use today exists for a reason. Technologies have life cycles: they are invented out of necessity and are often widely used as the best available solution to a given technical problem. For example, at one time … Continue reading
Fundamental application problem: Inductive prox sensor is latching on (or…failing to turn on) The prox sensor gap is set to turn on when the target approaches, but it does not turn off when the target recedes (latching on) The prox … Continue reading
Did you ever wonder how an Inductive Proximity Sensor is able to detect the presence of a metallic target? While the underlying electrical engineering is sophisticated, the basic principle of operation is not too hard to understand. At the heart … Continue reading
Don’t take chances with low-cost sensors. Some companies have been severely scaling back on sensor quality to meet price targets. Be on the lookout for these telltale signs of poorly engineered or manufactured sensors: Varying sensing distance: to drive out … Continue reading
