in new Penny + Giles in-cylinder transducer


P


enny + Giles – a product brand of Curtiss-Wright Controls Industrial and leading designer and manufacturer of position sensors, solenoids and joysticks – has introduced two new in-cylinder linear transducers suitable for intelligent mobile hydraulics. The ICT800 and ICT820 models combine the


best features of the company’s LVDT and


potentiometer technologies into a single, rugged and reliable displacement transducer which, using contactless inductive coil technology, means both provide an almost limitless and maintenance-free working life with a class-leading body-to-stroke length ratio. Additionally, both the ICT800 and ICT820 models have signal conditioning integrated into the transducer’s flange, which simplifies installation and eliminates interconnecting cables that can reduce the reliability of a control system.

Norbar launches new electronic torque wrench N


Advertorial


orbar Torque Tools has launched its first electronic torque wrench, the Nortronic®, designed to offer users unprecedented torque and angle control. To meet the demands of industry for quality control and production


traceability, Norbar has designed an electronic torque wrench that is capable of measuring, displaying, storing and transmitting torque and angle target results and receiving configuration settings from TDS (Torque Data System) computer software via a USB or wireless interface. The new electronic torque wrench will provide operators with a complete data management and archiving system. Two way data management capabilities also mean that multiple targets can be sequenced and linked as well as tool settings configured at PC. To find out more, visit http://www.norbar.com/nortronic.aspx and watch the product video at http://www.norbar.com/nortronic/nortronic-video.aspx.

Maple helps engineers design propulsion systems for some of the world’s biggest ships


MAN Diesel & Turbo, headquartered in Germany, is at the forefront of the quest for improved performance in marine propulsion systems. MAN designs and builds marine propulsion systems from 4 to 40MW in size,


with


controllable pitch propellers (CPP) of up to 11m in diameter and even larger for fixed pitch propellers. The world-leading technical computing software, Maple, from Maplesoft is playing an important role in keeping the propellers efficient and dependable, thus keeping costs down.


Mads Hvoldal is a mechanical engineer at the MAN Diesel & Turbo Propulsion Competence Centre division in Frederikshavn, Denmark. He works for the team that designs the mechanical and hydraulic control systems used to vary propeller pitch. “We produce a range of standard designs but it is the nature of the industry that many propulsion systems are engineered for specific vessels,” he explains. During peaks in demand for new vessels, development of hundreds of different designs per year is common. They need a software system that is robust and flexible.


“I had quite a lot of experience using Maple in hydraulic systems design in


hips keep the global economy moving. Whether they are ultra large crude carriers transporting oil from the Middle East, container vessels transferring manufactured goods from Asia or car carriers shifting vehicles from factories in Europe, the global maritime industry moves around 32 trillion tonne-miles of cargo every year, four times more than it did at the end of the 1960s.


S To deliver this dramatic increase in cargo, the industry has had to change


drastically over the past few decades. Vessels have become larger and more efficient as shipping companies work strenuously to keep costs down in the face of rising and ever more volatile fuel costs. For marine engineers, that means constant pressure to refine the performance and reliability of vessels and their systems. Nowhere is that pressure felt more acutely than in the most fundamental component of any modern powered vessel: its propellers.

a previous role,” he explains. “So I could see its potential benefits in our current work.” The critical advantage of Maple, he notes, is that the engineers can put the design equations in their original form right into the system. “That makes Maple faster to use, with reduced need to check and debug the code.”


MAN Diesel & Turbo, Propulsion Competence Center, Frederikshavn, has been using Maple for around six months and the power, speed and efficiency of the system has convinced its engineers that there is potential to expand their use considerably in the future. “So far, Maple has replaced our previous system for design calculations,” concludes Hvoldal, “But we are now exploring the feasibility of building standard models to simplify and automate the process further, and of automating the links between our initial calculations and the detailed part models in the 3D CAD system.”
