ELOVIS Gmbh develops, produces and markets electronic and optical measurement systems for the industry. ELOVIS products provide measurement, transmission and recording of productivity parameters, high-precision quality and process, and long-term stability. We focus on measuring lengths and speed without contact, as much as acquiring wireless data. Non-Elovis Contact coders are an alternative to the wheel with contact and conventional encoders. An interesting way to stop the slippage and loss of material when measuring length.
