  • Dental Burr - an overview | ScienceDirect Topics

    Dental burs have revolutionized the dentistry field and are used for cutting hard tissues such as bone or tooth [1,4,6–9]. They are normally made of stainless steel, diamond grit or particles, and tungsten carbide and fitted to a dental drill incorporating an air turbine. The dental bur was developed <300 years ago [8] and still widely used.

  • Flow Sensors Flow Meters | KEYENCE America

    With no moving parts, the sensor is not subject to mechanical wear, which ensures a long service life. There is also virtually no pressure loss in the pipe, so the pump uses even less energy. Unlike conventional electromagnetic systems, this device detects liquid from outside the pipe, making it highly resistant to insulating deposits inside the pipe while minimizing maintenance.
