Detect the loop of a band-shaped material. Loop controllers are used for the speed control of successive machines. In order to be able to hold de loop as constantly as possible, often an on-off control is not sufficient.
The analog sensor supplies the input signal for variable-speed drive. So a constant dip is achieved. The sensor measures the dip of a band material and supplies proportionally to darkening a similar output signal.
The transmitter depending upon model invisible infra-red chopped light or visible light of fluorescent tube.
The optical pattern created by the light-emitter is illustrated by an optic, with a camera angle of 35 degrees, in a photo module and created by it an output signal proportional to darkening of the light-transmitter (see following table).
non covered (freely)
High foreign light security, only the chopped-light of the transmitter will be analysed. The measuring signal is visualized by a LED line.
