1. An apparatus for coating a workpiece comprising wood, wood-based materials, or synthetic material, the apparatus comprising:
a pressing device for pressing a coating material onto a surface of the workpiece to be coated;
a conveying device for inducing a relative movement between the workpiece and the pressing device;
an activation device for activating a joining agent used for joining the coating material to the surface of the workpiece to be coated;
a temperature sensor for detecting a temperature of the joining agent, the temperature sensor being configured to send or receive a sensor signal for detecting the temperature; and
a shielding device for shielding a sensor section of the temperature sensor, the shielding device being at least partially integrated into the activation device;
wherein:
(i) the activation device comprises a barrier fluid outlet to dispense barrier fluid for shielding the sensor section, and
(ii) the apparatus further comprises a deflection device for deflecting the sensor signal, further wherein (a) the deflection device comprises a reflective element and/or (b) the deflection device comprises a signal guiding element.
