Detection of the presence of a product sprayed onto a surface
First Claim
1. A method of detecting the presence of a product sprayed onto an application surface, in which:
- a dose of the product to be applied to the application surface is sprayed onto a target zone of the application surface,characterized in that;
before spraying the product, the product is heated to a temperature higher than a predetermined temperature,after spraying the product, a value of a parameter representing the temperature of the target zone is measured remotely with the aid of remote measuring device, andthe value of that parameter is compared to a reference value of that parameter,wherein the remote measuring device captures a thermographic image of the product received by the target zone and in which that thermographic image is processed and analyzed with the aid of an image processor to quantify the quantity of the product received by the target zone.

Abstract
A method of detecting the presence of a product sprayed onto an application surface, in which the product to be applied to the application surface is sprayed onto a target zone of the application surface in pulses. Before spraying the product it is heated to a temperature higher than a predetermined temperature value. After spraying the product, a value of a parameter representing the temperature of the target zone is measured remotely, and the value of that parameter is compared to a reference value of that parameter. A detection installation including pulsed spraying by way of forming part of a device shared with the heating element.
