Embodiment Construction
[0028] figure 1 A sensor assembly 10 is shown comprising an optical sensor 12 and a cleaning device 14 associated with the optical sensor 12 . Such sensor assemblies can be used in paper processing machines for detecting the presence of paper, for example in printing presses.
[0029] Both the optical sensor 12 and the cleaning device 14 are connected to a common support member 16 .
[0030] In the example shown, the optical sensor 12 includes an optical fiber 18 having an end face 20 . This end face 20 constitutes a sensing surface 22 of the optical sensor 12 .
[0031] exist figure 2 and image 3 , the cleaning device 14 is shown in more detail. It includes a gas flow channel 24 having an inlet portion 24a, a middle portion 24b and an outlet portion 24c (see image 3 ).
[0032] The inlet portion 24a includes an inlet 26 to which air flow can be provided.
[0033] The outlet portion 24c includes an outlet 28 for discharging the airflow onto the target surface 30 of ...
