Abstract
The invention concerns a sensor arrangement for a coating system for coating workpieces, with at least one sensor for detecting at least one operating quantity of the coating system and for generating a corresponding sensor signal, a transmitter connected to the sensor for transmitting the sensor signal, a receiver for receiving the sensor signal transmitted by the transmitter, and a wireless connection between the transmitter and receiver.

17. A sensor arrangement for a turbine wheel assembly of a rotary atomizer comprising;
-
a shaft, a disk rotatable with said shaft and defining a marking surface, a sensor positioned adjacent said marking surface for reflectively detecting rotational velocity and direction of said turbine wheel assembly as said disk rotates about said sensor thereby generating an electrical signal, a transmitter receiving said electrical signal and emitting a wireless signal corresponding said electric signal, an evaluation unit, and a receiver spaced from said sensor for receiving said wireless signal from said transmitter thereby relaying said wireless signal to said evaluation unit for determining the rotational velocity and direction of said turbine wheel assembly. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. A sensor arrangement for a turbine wheel assembly of a rotary atomizer comprising;
-
a shaft, a disk rotatable with said shaft and having opposing sides with one of said opposing sides defining a marking surface and a plurality of turbine blades connected to the other of said opposing sides with said blades exposed to air for rotating said shaft, an optical sensor positioned adjacent said marking surface for reflectively detecting rotational velocity and direction of said turbine wheel assembly as said disk rotates about said sensor thereby generating an electrical signal, a radio transmitter of a first potential including a first antenna adaptable for receiving said electrical signal and emitting a wireless signal corresponding said electric signal, an evaluation unit, and a receiver of a second potential having a second antenna operatively communicated with said first antenna with said receiver being spaced from said sensor for receiving said wireless signal from said radio transmitter thereby relaying said wireless signal to said evaluation unit for determining the rotational velocity and direction of said turbine wheel assembly as said electric signal is transmitted between said first antenna and said second antenna.
