Connecting Wireless Temperature Controllers

Modern industrial temperature controllers are not just simple thermostats, as their earlier counterparts were. With the ability to control upwards of a hundred parameters, the latest industrial temperature controllers allow users to set not only temperature points, but also program alarm settings based on adjustable ramp parameters. Users can select the RTD or thermocouple they want to use for collecting data, while setting limits on the set points. With the advent of digital temperature controllers, Read more [...]

Do You Need EMC Testing?

Any electronic product faces a necessary hurdle before it goes to the market. It must clear the Electromagnetic Compatibility (EMC) test. This being a critical test in the design journey of an electronic product and passing this crucial test proves the design is right. However, most designers relegate this important emissions testing to a late part of the design lifecycle of the product. This unnecessarily increases the risk of cost overruns and project delays shortly before the planned launch. Read more [...]

Tracking Micro-Fluidic Flows

Scientists have taken analytical chemistry to such advancements that it can detect the effects of extremely tiny amounts of liquids—triggering the requirement of a need to measure such microflow of liquids. NIST, the National Institute of Standards and Technology, has produced such a microflow measurement device, the size of a nickel, and has filed a provisional patent application for it. The device is capable of measuring movements of nanoliters (nL) of liquid per minute. A nanoliter is a billionth Read more [...]

The Latest in Li-Fi

Newly developed technologies are allowing wireless networks to operate several hundred times faster than Wi-Fi—one of them is Li-Fi or Light Fidelity. Simply by switching on a light bulb, it is possible to encode data within the visible light spectrum rather than allow them to ride on radio waves as traditional wireless technologies such as Wi-Fi do. So far, research labs had confined Li-Fi within their closed doors. Of late, however, several new products using the Li-Fi technology has started Read more [...]

A Smart Development Board for the Raspberry Pi

The Raspberry Pi or RBPi single board computer when fortified with Cloudio makes a personal IoT computer that users can play with or use for prototyping. Cloudio, the add-on board suitable for the RBPi, offers advanced features such as sensor monitoring and displaying on dashboard, providing custom notifications with image and video, unlimited cloud services, one tap upload for multi-boards, voice assistant capabilities, IFTTT integration, drag and drop programming for Android and iOS, and much more. As Read more [...]

Mimicking Nerves with Memristors

Researchers are planning to build a computer mimicking the monumental computational power of the human brain. For this, they prefer to use memristors, because these devices vary their electrical resistance on the basis of the memory of their past activity. Memristors are semiconductor devices, and at NIST, the National Institute of Standards and Technology, researchers demonstrate the long and mysterious manner of the inner workings of memristors, explaining their ability to behave as the short-term Read more [...]

What is 3D MLC NAND Flash Memory?

To unleash performance fit for the next generation of computers, Transcend has released its MTE850 M.2 Solid State Device (SSD), based on 3D MLC NAND flash memory. The device utilizes the PCI Express Gen3 x4 interface and supports the latest NVMe standard. According to Transcend, this SSD targets high-end applications such as gaming, digital audio and video production, and multiple uses in the enterprise. Typically, such applications demand constant processing of heavy workloads, while not willing Read more [...]

What are Synchronous Condensers?

All manufacturing and industrial plants around the world face the unique problem of lagging power factor. Ideally, the voltage and current vectors should align perfectly for any AC power system feeding a load. In actual practice, however, the current either leads or lags the voltage by a few degrees, depending on whether the load is capacitive or inductive. Power factor is the cosine of the angle the current vector makes with the voltage vector as the reference. A positive power factor less than Read more [...]

Using Relays to Detect Faults

Different types of relays are in use in every-day life. These include relays constructed from electromechanical elements such as from solenoids, induction discs, hinged armatures, or from solid-state elements such as from transistors, magnetic or operational amplifiers, silicon-controlled-rectifiers (SCRs), diodes, or digital computers using microprocessors and analog-to-digital converters. Development of protection with relays began with the electromagnetic types, and most descriptions of relay Read more [...]

Industrial Controls and the Raspberry Pi

Industries with control equipment prefer to use a standardized system of mounting components such as circuit breakers within equipment racks. The most popular arrangement is the DIN rail and enclosure. The rails are typically made from a cold-rolled carbon steel sheet and zinc-plated or chromated for a bright surface finish. DIN is the acronym for Deutsches Institut fur Normung in Germany, and the rest of the world has adopted their standards as the EN and IEC standards. The famous single board Read more [...]
