The Industry-Leading Precision of Contrinex’s Analogue Inductives ‘Ring a Bell’ at SPS

Contrinex’s Analogue Inductive sensors offer industry-leading precision with an accuracy of a few microns (µm) and are trusted in a wide range of applications and industries. A challenge, however, is to visualise how small 1 or 2 microns (µm) is, or what a sensor with such precise measurement can do.

At the Smart Production Systems (SPS) exhibition in Nuremberg, Contrinex’s stand featured a display visualising the precision of its analogue inductive sensors, which were, on this occasion, used within its SMART measurement sensors. The display featured a metal cylinder, and visitors were encouraged to squeeze it like a fairground test of strength.

No matter how hard you squeeze the cylinder, you cannot feel any movement, but the analogue sensor can. The sensor’s output, which is shown on a screen, is encouraging, showing a large amount of movement when you squeeze the cylinder hard. This was devalued somewhat when a colleague flicked the metal cylinder with a finger, and as can be seen in the video, the sensor shows the movement within the cylinder, which rings like a tuning fork.

To explain the technology, Contrinex’s analogue inductive sensors provide industry-leading precision with long sensing ranges of up to 40mm because they use the Condist® oscillator technology. This ensures the inductive sensor has excellent temperature stability and repeat accuracy, essential for precision measurement in the µm range.
