In-cylinder transducers keep welding
accurate
AI Welders Ltd recently discovered an application for Penny and Giles HLP100 in-cylinder transducers in a bespoke automatic flash welding machine
AI Welders Ltd of Inverness manufacture automatic flash welding machines for a wide range of industrial applications, either for stand-alone operation or installation in automated production lines They have been specifying Penny and Giles linear transducers for 35 years and currently use HLP190 hybrid linear potentiometers for position feedback in the machines' servo weld control systems

Digital panel indicators at very competitive price
Two new ranges of fully programmable, digital panel indicators from Penny and Giles Controls Ltd - offer high performance features at a very competitive price.
However, the company also recently discovered an application for Penny and Giles HLP100 in-cylinder transducers in a bespoke automatic flash welding machine that was designed for a leading crane manufacturer in France.
The £1 million machine will be used to weld mast components for the company's tower cranes.
Whilst the twelve HLP190s fitted to the machine are used for their traditional position sensing duties, the HLP100s are used as limit switches in a component alignment system.
A moving platen maintains alignment and data from the HLP100s help determine its position, velocity and start and finish positions during the weld sequence.
As a spokesman for AI Weld explains: "We need to know the position of the platen at all times to an accuracy of 1/1000 of an inch.
Using the HLP100s as limit switches is usual, but their combination of accuracy and rugged design makes them ideal for this application." He adds that the HLP100s' in-cylinder application also helps to clean up the exterior of the machine.
Although AI Welders have not used in-cylinder HLPs before they are confident of their performance and reliability.
Says the spokesman "We built a machine in 1985 fitted with Penny and Giles transducers that we embedded ourselves.
They have given exceptional performance over the past 15 years and they and the machine are still working today." He concludes by saying: "For 35 years Penny and Giles transducers have been vital components in our machines and have given us virtually no problems. Request a free brochure from Penny + Giles ...
Now that our designers have discovered the potential of these in-cylinder HLPs I think we shall be using many more in the future.".
