Different Types of Industrial Cables

To wire up different components within electronic gadgets, hook-up and lead wires may be adequate, but the electric industry needs a vast variety of industrial cables to remain connected. Chief among these are power cables to carry high voltages and currents, and cables necessary for industrial automation and process control. Cables may conform to multiple standards such as UL, CSA, and others. Cables often have to transmit power or signal in industrial environments that may harbor the harshest conditions Read more [...]

What Influences Industrial Connectivity?

In the industry, any component coming in the path of delivering control signals or power to do useful work is termed industrial connectivity. For instance, components including relays, motor starters, terminal blocks, and connectors are all typical connectivity components. Generic connectors can use low-cost material as they merely maintain electrical continuity. However, based on operating environments, connectors are differentiated into four categories: hermetic, military, industrial, and commercial. Read more [...]

Importance of Resolution in Thermal Imaging

Thermal imaging technologies have long been associated with a range of applications and industries for discovering abnormalities and weak points quickly and efficiently. These technologies are ideal for production monitoring and other applications as materials and components undergo non-destructive testing under operating conditions. That allows discovery of the problem before a breakdown can occur or a fire risk can develop. For instance, thermal imaging allows contractors in a building, facilities Read more [...]

What are Miniature Circuit Breakers?

Most places that earlier used fuses in low voltage electrical networks now commonly use miniature circuit breakers (MCB) instead. Although an MCB is much larger than a fuse holder is, the MCB has several advantages when compared to fuses. Any abnormal condition of the network, meaning overload or fault conditions, causes the MCB to sense and automatically switch off the electrical circuit. While a fuse does not sense it, the MCB senses the abnormality in a more reliable way. Additionally, the Read more [...]

LCD Touchscreens for the Raspberry Pi

Those using the single board computer, the Raspberry Pi (RBPi), can now get several high-resolution LCD screen models on the market. While they are cheap, some are designed to integrate with the RBPi specifically. SunFounder, a company specializing in accessories and kits for RBPi and Arduinos, produce a series of these screens. For satisfying different segments in the market, SunFounder has lately produced and is marketing a number of models with varying price ranges. SunFounder LCD 10.1” HD With Read more [...]

How Do Air and Magnetic Hydraulic Circuit Breakers work?

Circuit breakers have replaced fuses in most electric circuits. As these are easy to select, install, and maintain, circuit breakers are more commonly employed as protection against over-current and shorts. For different applications, there are various types of circuit breakers available in the market. We will discuss two of them. Air Circuit Breakers Air circuit breakers use air as the medium for extinguishing the arc formed when the breaker trips. The air is usually kept in compressed form Read more [...]

How Long Does it take for a Circuit Breaker to Operate?

Electrical power systems all over the world use circuit breakers as important and critical components. As they play a key role, engineers periodically test circuit breakers. One of the most important test methods is the timing test, which measures the mechanical operating time of the breaker’s contacts. A timing test averts damage to a circuit breaker, as the incorrect operation of a circuit breaker prevents fatal consequences on connected equipment and substation personnel. Various measuring Read more [...]

Metal Bellows in Engineering Applications

Metal bellows are versatile and a key enabling technology for a wide range of engineering applications. They play an essential role in controlling motion, vacuum, and pressure. Numerous industry sectors use metal bellows in a broad array of machine assemblies and components. Being flexible, spring-like, and precision-engineered components, metal bellows are typically custom-designed, performing a variety of engineering functions. Metal bellows can convert temperature, mechanical, and pressure Read more [...]

How Does Ladder Logic Work?

Over the last 30 years, there has been a significant evolvement of ladder logic for industrial controllers. It now supports advanced functionality that includes data acquisition, networking, data manipulation, motion control, and process control. Designers starting a new control system are faced with many basic functions this tried-and-trusted language needs to perform, and it does so, almost effortlessly. Object Detection Detecting the presence of an object is one of the most pervasive functions Read more [...]

PiFM: A Pirate Radio with the Raspberry Pi

The popular single board computer, the Raspberry Pi (RBPi), can work as a radio transmitter as well. Using a simple hack, you can turn your RBPi into a powerful FM transmitter with adequate range to cover a bike parade, high school ball game, silent disco, DIY drive-in movie, or even your entire home. However, the broadcast frequency covered by the RBPi is rather large—one to 250 MHz, and there is a possibility this will interfere with government bands. Therefore, it is advisable to limit the transmissions Read more [...]
