A new generation of ultrasonic forked sensors

Leuze: The established range of forked sensors with ultrasonic technology from Leuze has been developed to a new level, offering users a range of innovative functions and unique performance credentials.

The ultrasonic forked sensors developed by Leuze electronic for label detection are capable of recognizing every conceivable material combination with paper, film, metallized film labels or thin metal film on all kinds of different backing materials with a high degree of dispensing accuracy. Its generous mouth width allows it to easily cope with non-standard label types such as booklets or leporellos. Leuze has now taken this product series onto a higher development level, and with its new IGSU 14B is offering a range of innovative functions plus unique performance credentials.

Users already familiar with the proven Leuze forked sensor series GSU 14 will immediately 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 operation such as dirt accumulation or a changed signal threshold. This permits timely intervention or maintenance to be carried out, and so increases process reliability.

The “B” at the end of the new type designation denotes the new device generation in which a range of innovative functions simplifies handling and further developed technological features ensure maximum functional reliability and availability. Right from the commissioning stage, users are supported by the new Easy Teach function. This simplifies the commissioning process, requiring only the single push of a button. This function allows the IGSU 14B to independently recognize the signal level with which it is able to work. Also unique is the new auto level control (ALC) function which provides for maximum performance reserves through independent online optimization of the switching threshold. It is offered as an optional function by Leuze 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 recognized and automatically assimilated.

Featuring a more compact metal housing, the performance of the new IGSU 14B is characterized by high precision and processing speed coupled with short response times of just 100µs 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. With this catalogue of benefits, the new product range offers the highest processing speed and reliability offered by any ultrasonic forked sensor, coupled with outstanding handling simplicity.
