IMS Shapemeter Roll Metal Service Centres

Shapemeter Roll

Shapemeter Roll

The shapemeter roll (BFI principle) consists of a solid roll body equipped with a project-specific number of piezoelectric sensors.

The sensors are distributed over the entire roller body as required for the specific measurement task.

The measured value of each sensor is amplified in the roll body, digitised and transferred from the rotating part (rotor) to the static part (stator) of the flatness measuring roll via an optical and wear-free rotary transmitter.

#IMS Expert

Dirk Reimertz,
Dipl. Engineer

…to the verifiability of flatness previously required, your best customer suddenly also needs the exact geometry of the plates to be delivered. Do you now lose the order or is there a possibility to retrofit a measuring system despite the cramped conditions? What advantage does this investment bring me, apart from the fact that it satisfies just this one customer?

Not only in slitting and cut-to-length lines, but also in pickling lines, recoiling lines and inspection lines, it is necessary to meet growing customer demands on product quality. These are challenges that I am confronted with every day and for which we at IMS have developed a product portfolio specially tailored to metal service centres.

We set new standards with our systems and reach new dimensions with our efficient, digital and durable measurement technology. The systems are designed precisely for your application, and with our Life Cycle Partnership you are always on the safe side.”
