dbk+4The latest type of ultrasonic double sheet control. Three variants: for all imaginable fitting positions. Highlights > 3 control inputs > for trigger, Teach-in and external sensitivity settings for > IO-Link interface > for support of the new industry standard > Teach-in option > e.g. for probing wafers stuck together by a water film > Variant with 90° angled head > for individual installation situations > Variant with external M18 receiving transducer > Variants with very compact transmitters and receivers in the M12 threaded sleeve > UL Listed > to Canadian and US safety standards Basics...

The task of double-sheet control is to identify two or more pieces or sheets inadvertently adhering together. The functional principle A high-frequency ultrasonic transmitter beams against the sheet from the underside. The beamed signal induces the material to vibrate. The effect of these vibrations is a very small sonic wave on the other side of the sheet being spread. This wave is evaluated by the ultrasonic receiver on the opposite side. The signal from the stacked sheet ("double sheet") is so weak that it hardly gets to the receiver. The dbk+4 detects missing, single and double sheet. Functional...

The "Thick" setting is available for paperboard containers and fine-corrugated card. Changes between the working ranges can be undertaken under on-going operations. A Teach-in for the material to be scanned is not necessary. If the 3 control inputs stay unconnected, then the dbk+4 operates in the standard working range. As such, a very broad material spectrum can be scanned. Teach-in The Teach-in function is additionally available for materials which cannot be scanned with one of the three working ranges. A material Teach-in is done by inserting a single sheet into the double-sheet control. The...

Double-sheet control Material-conditioned fitting position With papers and thin films, the double-sheet control is effected perpendicularly to the material; flapping does not impair the function. In the case of fine-corrugated card, thin sheet metal, wafers or thicker plastic films (e. g. credit cards), the dbk+4 should to be mounted at a specific angle of inclination α to the material running through. Fine-corrugated card can be optimally dimensioned at an inclination of α ≥ 35°, thin sheet metal or thicker plastic films at 27° and wafers at an angle of 11° dbk+4 Ultrasonic double-sheet control...

The dbk+4 operates as standard in the free-run mode. This means that the dbk+4 cyclically carries out measurements at a high measuring rate. Under ongoing operations, the working range can be changed and a teach-in carried out by means of the C1 to C3 control inputs.

a) Standard: dbk+4/3CDD/M18 E+S and dbk+4/3CFF/M18 E+S The standard: receiver and all the evaluation electronics are housed in an M18 threaded sleeve, which is only 60.2 mm long. The transmitter is housed in an M18x21 mm threaded sleeve and a 2-pin plug connects it to the receiver. b) Receiver with 90° angular head: dbk+4/WK/3CDD/M18 E+S and dbk+4/WK/3CFF/M18 E+S As with the standard, but here the receiver is arranged at right angles to the M18 threaded sleeve. c)dbk+4/M12/3CDD/M18 E+S and dbk+4/M12/3CFF/M18 E+S The M12-heads variant has an optimum spacing of 20 mm between transmitter and receiver....
