Last year, we were asked to design a sensor to measure the grip strength of a golden eagle named Tilly, for the award-winning BBC documentary series, Natural World.

Challenge – to find a load cell that could withstand the estimated grip strength of an eagle.

As Tilly had been trained to catch and grip a tennis ball, the load cell needed to be small enough to fit inside a similar-sized measuring device yet withstand Tilly’s tremendous grip strength.

Thanks to their unique design, our DBBSMM miniature s-beam load cells were ideal for the job.  Not only are they very compact but their s-shaped design offers superior side-load rejection and high accuracy.

20 years ago, we were approached by The Royal Greenwich Observatory in Cambridge to design and build nearly 700 bespoke load cells for two 8.1m diameter telescopes known as The Gemini Project.

Now 20 years on, these custom-made load cells are still consistently and accurately performing an integral part of the telescope’s control system.

To continue to deliver accurate and detailed astronomical images, we have been asked to re-design and manufacture custom load cells to the same specifications incorporating up-to-date electronics with the latest state-of-the-art amplifiers.

See how we did it.
