(54) Device for checking delivery of fluid or semifluid products


(57) The device checks whether a spray apparatus (1) for fluid or semifluid products, for example abrasive pastes, paints or lubricants, emits or does not emit product spray. The check is made by a radiation beam (17, 18, 14A, 14B) disposed to intersect the jet. To prevent any soiling by sprayed product being able to falsify the check and thus impair the device, pneumatic means are provided for preventing such soiling.
