Overview
The UD18-2 specializes in checking for double layers and splices using ultrasonic technology. Operating with precision, it is able to determine whether one, two or no material layers are present between its sender and receiver. Where the UD18-2 really excels is checking for double layers in paper, cardboard, shiny metal, and transparent plastic.
It is possible to teach in up to four sensitivity levels and switch between them during operation, allowing the sensor to tackle even the most complex of applications and ensure permanent system availability with a consistently excellent level of production quality.
