Certainty beats uncertainty

Performing angular and rotary calibrations and sensor checks has a unique set of challenges. If your process isn't fit for purpose, you might be familar with some of these issues:

  • Uncertainty and repeatability issues that can potentially compromise your results
  • A lack of automation and programmability that requires excessive manual intervention
  • Insufficient robustness in equipment leading to excessive and unacceptable downtime
  • An operation that doesn't offer the level of scalability that would be optimal


Select a solution that provides automation, durability and precision

The positioning and indexing range of products is designed to perform their task accurately and reliably. The wide range offers solutions that can be configured to operate automatically, and offers a wide range of payload options meaning that anything from small artefacts to multiple sensor configurations can be tested and calibrated.

Benefits of the RPI range

Precision in all we do

Calibrations and tests run smoothly with the range. Angular accuracies as good as 0.5 arcseconds and angular repeatability as good as 0.2 arcseconds means that measurement uncertainty contribution is small enough to be ignored.

Shop floor design as standard

It goes without saying that we supply shop floor suitable items.  But did you know that goes for all our entire rotary range?  Every product we make is designed for the rigours of shop floor use.  Whether you intend to operate in the lab or the shop floor, you can expect the same high level of performance.

Large Range of Options

The range offers devices that operate in multiple orientations, have multiple programming options and support many tooling and mounting configurations meaning that your solution can be designed to work in exactly the way you need it to.
