Abstract: The disclosure relates to a coating device, in particular a rotary atomizer, for coating components, in particular motor vehicle body components, with an electrostatic coating agent charging system, so that the coating device comprises a high-voltage area and an electrically grounded area. Furthermore, the coating device comprises a sensor in the high-voltage area, in particular as a rotational speed sensor for measuring the rotational speed of the rotary atomizer, and an optical waveguide for transmitting a measurement signal of the sensor from the high-voltage area to the electrically grounded area, wherein the optical waveguide enables a potential separation between the high-voltage area and the electrically grounded area. The disclosure provides that the sensor is a magnetic sensor.

Abstract: The disclosure relates to a coating device for coating components with a coating agent (e.g. paint), having a protected area which is explosion-proof and/or is under high voltage during operation and an unprotected area in which no explosive atmosphere prevails during normal operation. A plurality of sensors that measure process variables of the coating device are included with the sensors being arranged in the protected area. A data interface for external data communication, the data interface being arranged in the unprotected area is also included. A transmission system transmits data between the sensors in the protected area on the one hand and the data interface in the unprotected area.

Abstract: The disclosure relates to a coating device (e.g. painting robot) for coating components (e.g. motor vehicle body components) with at least one electrical consumer which requires electrical energy for operation. The disclosure provides a transmission system for wireless transmission of the electrical energy required for operation of the at least one consumer to the consumer and/or for transmission of data from and/or to the at least one consumer.
