ABSTRACT:
The invention device measures the instantaneous rotation speed of a turbine (6) which is housed inside the body (3) of the paint sprayer (2) and which rotationally drives the rotating bowl (5) when the paint sprayer is mounted on the end of an arm (8) of a robot or an analogous multi-axis machine. A disk (10), which is disposed to the rear of the turbine (6) and which rotates therewith, cooperates with the front end (11a) of an optical-fiber-type light guide (11) which is interrupted (11b) at the rear (7) of the body (3) of the paint sprayer (2). Transmitting and receiving optoelectronic means are mounted on the end of the arm on the mounting plane (9) of the paint sprayer, opposite the rear end (11b) of the light guide (11). Said means convert a reflected optical signal which is carried by the optical guide (11) into an electronic signal which is carried by an electric cable (22) placed in the arm (8). The inventive device is suitable for use with machines on automatic painting lines for automotive vehicles.
