The most recent addition to the Leuze Electronic ultrasonic forked sensor range, the IGUS 14B, offers what is claimed to be the highest processing speed and reliability of any ultrasonic forked sensor, coupled with outstanding handling simplicity.
In terms of performance, the forked sensor has high precision and processing speed, coupled with short response times of just 100us with a maximum belt speed of up to 240m/min and material-dependent repeat accuracy is as high as +/-0.2mm, even at a high dispensing rate.
It is this level of specification, together with a generous mouth width, that enables it to cope easily with standard and non-standard label types, making the IGUS 14B suitable for virtually any packaging/labelling application and every conceivable material combination of paper, film, metalised film labels or thin metal film on all kinds of backing materials.
Readers familiar with the Leuze forked sensor series GSU 14 will notice the added 'I' in the type designation. This is an identifying feature typically used by Leuze to denote a separate warning input. This type of device has its own integrated self-monitoring facility and is capable of indicating errors during teach-in and in operations - such as dirt accumulation or a changed signal threshold. This permits timely intervention or maintenance to be carried out, and hence increases process reliability.
Another key benefit of the IGUS 14B is the Easy Teach function that simplifies the commissioning process, requiring only the single push of a button. This function enables the new sensor to recognise the signal level with which it is able to work. Also setting new levels of sophistication is the new auto level control (ALC) function that provides for maximum performance reserves through independent online optimisation of the switching threshold. It 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 assimilated automatically.
The IGUS 14B joins an already formidable sensor range that enables Leuze to satisfy many applications in food and beverage processing lines, as well as rugged industrial applications.
