The range of Leuze forked sensors incorporating ultrasonic technology has been developed to a new level, offering users innovative functions and unique performance credentials.
The range of sensors, developed for label detection, are capable of recognising every conceivable material combination with paper, film, metallic film labels or thin metal film on different backing materials with a high degree of accuracy. The sensor’s generous mouth width allows it to easily cope with non-standard label types.
The IGSU 14B includes a separate warning input and has its own integrated self-monitoring facility making it capable of indicating errors during teach-in and in operation. Examples would include dirt accumulation or a changed signal threshold, and this permits timely intervention and so increases process reliability.
Right from the commissioning stage, users of the new sensor are supported by the new Easy Teach function. Requiring only a single push of a button, this significantly simplifies the commissioning phase. This function also allows the forked sensor to independently recognise the signal level with which it is able to work.
Another innovative feature is the new auto level control (ALC) function which provides for maximum performance reserves through independent online optimisation of the switching threshold. This is offered as an optional function and is recommended particularly if minor material differences are anticipated in otherwise identical label types. In this case, slight changes in the signal level are recognised and automatically assimilated.
Featuring a more compact metal housing, the performance of the new IGSU 14B is characterised by high precision and processing speed, coupled with short response times of just 100 μs with an admissible belt speed of up to 240 m/min. Material-dependent repeat accuracy is as high as ±0,2 mm, even at a high dispensing rate.
