WST HSC 4-60 High Speed Control The WST HSC4-60 High Speed Control Signature Sensor System works in a way similar to the function of a human eye. In contrast to most of the camera systems our HSC sensor head checks without any data reduction. The sensor monitors each signature through a dynamic reading and captures monochrome and multicolor values from a 13 mm (1/2”) wide reading track. The central computer is responsible for the administration and communication within the network. Make-ready is very simple and is done by only one operating button.
