特徴とするスプレイによる塗膜の制御装置。1. A light-emitting element and a light-receiving element of an infrared monitoring device are placed opposite to the spray of a coating solution mixed with a solid lubricant etc. from a spray gun. This light receiving element is connected to the panel's digital voltmeter circuit for spray concentration display via an amplifier.
In addition, in parallel with this, an upper limit setting circuit and a lower limit setting circuit for the spray coating liquid concentration are connected separately, and a comparator is connected to each of the upper limit setting circuit and lower limit setting circuit to detect when the spray concentration exceeds the set value. In addition to connecting the alarm circuit (indicator light and sound) in case of
The two comparators are each connected to a control circuit operated by an upper limit setting circuit and a lower limit setting circuit,
A control device for a coating film by spraying, characterized in that the control circuit activates a control mechanism for the flow pressure or flow rate of the spray coating liquid.
