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.
Screw conveyors are a popular choice for bulk materials handling and can be used for a range of products, from food and pharmaceuticals through to grains and animal feed, chemicals and minerals. The machines have a simple, robust design and present an easy-to-maintain, cost-effective and versatile option for material transport. This introductory article from Guttridge looks at how screw conveyors work, focusing on the factors that affect design and, consequently, cost.
As IRISS explains in this Tech Byte, visual inspection of plant equipment is one of the most useful tools available. A good set of eyes and the ability to see subtle changes in equipment is invaluable. For more than two decades, predictive maintenance (PdM) technicians have used best practices to walk around equipment seeing, smelling and listening before they open their PdM toolbox and begin an infrared, ultrasonic or vibration inspection. A new drip pattern on the floor, a change ...
One of the most common needs in engineering is to join two or more parts together. Usually, the main requirement is for a secure and long-lasting bond, although the ability to undo the joint at will is not uncommon. Here, John Marshall, technical engineer at WDS Component Parts, reviews the relative merits of various fastener and adhesive options.
A mechanical structure based on serial stacking of level arm has been designed in order to amplify the ingoing force of the harvester system. The outgoing force is applied on the smart material. The deformation of the mechanical structure is based on flexural pivots using four truncated circular collars. The last amplification is based on the amplified piezoelectric actuator (APA) shell from Cedrat Technologies.
US Air Force studies for the last 20 years have shown that the application of certain corrosion-inhibitive lubricants (CILs) or corrosion-preventative compounds (CPCs) can substantially affect CND and RETOK rates, thus improving avionics reliability. This paper from Envirotech addresses prior research and the current operational and depot-level application of CIL/CPCs in the US Department of Defense.
They can be despatched to inspect the safety of oil rigs, deployed on the military front line to assess combat dangers, enter active volcanoes and perform less invasive surgery. While robots might be the good guys when it comes to improving productivity, handling precision tasks and boosting workplace efficiency in manufacturing and automation environments, the safety of workers operating alongside robots should always be the prime consideration.
