Reinforced grill

Tech Byte: will the reinforced grill affect measurement? downloadweblink

IRISSThu, 26 Mar 2015

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.

Technical article: active heave — how to accumulate more energy savings downloadweblink

Bosch RexrothThu, 26 Mar 2015

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 ...

Power transformers

Technical article: power transformer design and analysis with Flux download

CedratWed, 25 Mar 2015

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.

Trends in the design of electronic goods affect the choice of fasteners

Technical article: trends in the design of electronic goods affect choice of fasteners downloadweblink

TR FasteningsWed, 25 Mar 2015

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.

Detection is among the key tasks in intralogistics

Technical report: demands on sensors and readers in conveyor and storage systems downloadweblink

Leuze ElectronicTue, 24 Mar 2015

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.

Technical article: how to ensure sensors operate in extreme environments downloadweblink

Sherborne SensorsThu, 12 Mar 2015

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.

Technical article: understanding the factors that affect the cost of screw conveyors downloadweblink

GuttridgeWed, 11 Mar 2015

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.

Visual inspection

Tech Byte: don't forget the walk-around downloadweblink

IRISSMon, 9 Mar 2015

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 ...

Nowadays there are many industrial adhesives available to design engineers. Each one is formulated to provide set characteristics, so there is a need to identify the best for each situation

Technical guide: WDS's technical engineer discusses adhesives and fasteners downloadweblink

WDSMon, 9 Mar 2015

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.

The working concept

White paper: mechanical structure for piezoelectric harvester application downloadweblink

Cedrat Technologies S.AMon, 9 Mar 2015

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.

White paper: effects of corrosion-inhibitive lubricants on electronics reliability downloadweblink

Envirotech EuropeFri, 6 Mar 2015

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. 

Worker safety is a top priority in all robot applications

Technical article: putting safety first and foremost when working with robots downloadweblink
