LVDTs get better linearity... and
cheaper
Penny and Giles Controls has both improved the performance and reduce the price of its AF111 and AF145 LVDTs.
Following the introduction of 'cell' manufacturing for its range of rugged, high integrity LVDT displacement transducers, Penny and Giles Controls has been able to improve the performance and reduce the price of its AF111 and AF145 LVDTs The most significant improvement is in the linearity performance of both models

Penny + Giles has added to its range the JC6000 robust multi-axis joysticks designed for demanding operator control applications.
For strokes from 75 to 150mm, independent linearity is now +/-0.125% - a 100% improvement! For strokes from 5 to 50mm the specification is now +/-0.2%.
Both figures were previously +/-0.25%.
To provide high overall system accuracy the AF111 and AF145 LVDTs have been designed primarily for use in the "difference over sum" (or ratiometric) configuration, where the output is unaffected by temperature and supply current changes.
However, they can also be used in the differential output configuration more commonly used by other LVDT manufacturers.
Both models have a very small transducer body-length/stroke ratio (Penny and Giles claims it is better than any other LVDT currently available).
A Penny and Giles spokesman says they are able to pass on the 5% price reduction per unit as a direct result of cost savings made from new cell manufacturing techniques for standard catalogue items.
At the same time the company has announced that it has frozen prices for its latest sealed linear sensors for 2001.
Current models include the SLS130, SLS190 and SLS320. Request a free brochure from Penny + Giles ...
