Micro-electromechanical systems (MEMS) have come into wide-scale use in the last few years, and the trend does not appear to be slowing down. In industries such as automotive and consumer electronics manufacturing, there is a growing use of accelerometers and gyroscopes being seen. This article from Sherborne discusses the manufacture of MEMS sensors.
There are a host of possible explanations that might help explain seemingly contradictory study results, according to Minitab. Perhaps the studies utilised different designs, different statistical methodologies, different survey techniques, different confounding variables, different clinical endpoints or different populations. Or perhaps there’s something even more fundamental at play. The proverbial elephant in the room of any statistical analysis. The essential, pivotal question upon ...
The purpose of this paper from IRISS is to educate on the subject of transmission values for infrared windows — does a high value equal more accuracy? Or is knowing the percentage of transmission more important? The paper also discusses transmission values for infrared windows: how does a ‘grill’ affect transmission? Will it make quantitative thermography null and void?
According to Dixon Group Europe, it is important to identify the threads required before ordering couplings. Identifying threads can sometimes be the most difficult and frustrating part of coupling selection. However, without the right combination of threads, you may not provide a functional or safe connection.
The materials available for infrared (IR) window optics are diverse and have a variety of transmission rates and mechanical strengths. It is advisable that when considering the use of IR windows, you seek advice from IR window manufacturers and IR lens material suppliers before deciding the materials and window styles best suited to your application.
Electrical accidents happen daily; however, there are steps that companies and individuals can take to reduce the occurrence of these accidents and protect everybody concerned from the consequences. The National Fire Protection Association provides, in its regulation 70E, a reference for facilities to meet the requirements of electrical workplace safety and its regulation 70B outlines the best practices for setting up and maintaining an electrical preventative maintenance programme.
You are correct when you state that the grill will affect your measurements. In fact, all infrared (IR) window lenses affect the transmission rate of the target temperature. Regardless of the type of IR window you are using, you need to test and adjust your IR camera for the transmissivity of the lens material you are using. This value can vary by camera even if it is the same make and model of camera. This is due to differences of the detectors in the IR cameras.
With oil becoming harder to exploit and prices increasing, operations are moving into deeper waters. Active-heave users need to move towards more energy-efficient solutions as subsea activity needs more power to deploy the equipment to reach these hidden depths. Steve Smith, marine and offshore sector manager at Bosch Rexroth, says by innovative system design and integrating accumulators into the active-heave compensation control process, end users could achieve energy savings of up ...
Nowadays, it is important to optimise the efficiency of power transformers to make sure minimum losses are generated from the various physical phenomena. Finite element studies allow the transformer designers to accurately analyse the different losses to enhance the performance of their transformers. A few steady-state and transient tests allow the user to determine the electrical and mechanical constraints that the power transformer will have to endure in its life.
Where once it was believed that design would always be predicated on the need to take things apart and repair of recycle them, the fact is that the opposite has increasingly become true. As this article from TR Fastenings explains, electronic devices, in particular, have seen a fundamental shift whereby disposability is increasingly considered the norm — even in expensive devices.
As Leuze electronic explains here, the ongoing automation in many industries is constantly facing new challenges resulting from the required flexibility. In order picking as well as in production and further processing, widely varying goods follow in direct succession. As a result, it must be possible to quickly and easily change over and adapt today’s machines from large series with identical objects to individual products — ideally in an order-related, not batch-related manner.
In this interview, Malcolm Diamond, executive chairman of Trifast, whose Sussex-based trading arm TR Fastenings manufactures and distributes industrial fastenings and associated components, discusses different markets, the factors underpinning the company’s growrth and opportunities on the horizon.
It is necessary to measure the resistance of all wires and cables that are used to distribute power, including the cable used to wire domestic property, says Nathan Barwell, business development engineer at Seaward Group.
Dr Louis Raymond is a materials scientist with more than 30 years’ experience as consultant, educator, diagnostician and forensic scientist. Here, he answers frequently asked questions related to the cause of fastener failures.
According to Mike Baker at Sherborne, sensors will often be called upon to operate in extreme environments, withstanding effects such as heat, mechanical stress/shock and vibration, as well as working within areas of electromagnetic interference. Under these conditions, it is vital that sensors are able to maintain a consistently high level of accuracy and reliability.
