WE HAVE A DISPENSER FOR LOCTITE.BUT IN AUTO MODE NO DETECTION IS POSSIBLE WHETHER THE DISPENSER DELIVER LOCTITE OR NOT.THE QUANTITY FOR THE CYCLE IS JUST ONE DROP EVERY 1 MINUTE AND DIFFICULT TO USE CONVENTIONAL OPTO SENSOR SINCE IT IS INTERMIDIATE.IS THERE ANY SENSOR WHICH SENSES THE PRESNCE OF LOCTITE ON THE ROLLER AND ALSO ENSURE IT IS WET

I would experiment with something on the order of measuring capcitance between a plate located a small distance away from the roller and the roller. The Loctite might change the dielectric constant, therefore capasitanse.
