What is a Photoelectric Sensor?

 In this post, we will learn the working principle of a photoelectric sensor, and the types, and features of these sensors. The photoelectric sensor is a very important technology used in instrumentation. It makes optics and photo electricity into picture for working. As a transducer, it converts light energy into electrical energy. It is used in many industrial automation applications. In this post, we will see the concept of a photoelectric sensor. What is a Photoelectric Sensor? A photoelectric sensor emits light from the transmitter, which consists of a light-emitting element. A receiver at the other end will detect this light beam. When this emitted light is cut by any object in between, the light beam intensity received at the receiver changes. The light intensity is continuously processed and converted into an electrical output. As the intensity changes, the electric output changes. This electrical output is then fed to any circuit and shows whether any object has passed bet...

What Size Torque Wrench Do You Need?

 Fasteners such as head bolts and lug nuts help securing different parts that are under constant tension and stress. They come in different sizes and levels of hardness. Screw thread type fasteners must be tightened to a specific amount of torque. Hence, we use Torque Wrenches to do this job. But an important question is: What Size Torque Wrench Do You Need? In this guide, we will see briefly about Torque Wrenches, types of torque wrenches and what size torque wrench to use. An Overview of Fasteners and Torque Any decent automobile technician must know about different types of fasteners (nuts and bolts), tightening procedures, what size torque wrench to use, etc. Speaking of tightening fasteners, we should not over tighten or under tighten it as it can damage or break or become loose over time. But how do we make sure that a fastener is tightened properly? This is where the torque specifications of nuts and bolts come handy. As it is difficult to precisely measure the tightening fo...
