The invention relates to an ultrasonic standing-wave atomizer arrangement for producing a paint spray mist for painting a workpiece, with a sonotrode, with a component arranged lying opposite the sonotrode, a standing ultrasonic field being formed in the intermediate space between the at least one sonotrode and the component in the case of operation. At least one nozzle-shaped paint feeding device is arranged perpendicularly in relation to the center axis of the sonotrode and introduces the paint into the intermediate space for the atomizing process at least one paint discharge point, the component arranged lying opposite the sonotrode being a coaxially aligned reflector, and the end face of the latter, facing the sonotrode, having a step-shaped recessed formation and the depth of said recessed formation corresponding to a multiple of half the wavelength &#x3bb; of the sonic vibrations in air that are produced in the sonotrode.

Ultrasonic standing-wave atomizer arrangement

A sensor for a conductive coating delivery system subject to high voltage including a movable member, such as a pig received through a delivery line having a magnet and a sensor in the delivery system subject to high voltage including an optically polarizing device subject to magneto-optical change upon approach of the magnet generating a polarized light signal, optical fibers connected to the sensor receiving the polarized light signal connected to an electrical device situated remotely from the high voltage generating an electrical signal for controlling a valve, metering pump or the like.

Pig sensor arrangement for high voltage coating system

A rotary atomizer with external charging which can be used for applying conductive paints, in particular water-based paint, to a surface of a body to be coated. The rotary atomizer has a directing air ring at a high-voltage potential and an earthed spraying bell. To reduce the risk of discharges, it is proposed to connect the ring to an earth potential via a high-impedance resistance, so that the ring assumes a potential which lies between the high-voltage potential of electrodes for the external charging and the earth potential of the bell.
