High-​Precision Laser Dis­tance Sen­sors with Ether­CAT Set New Stan­dards

The pre­cise dis­tance sen­sors in the PNBC se­ries set a new mi­les­tone: The dis­pla­ce­ment sen­sors pre­ci­se­ly mea­sure even the smal­lest dif­fe­rences, even from great dis­tances. The op­tics of the laser sen­sors en­able re­pro­du­cible mea­su­re­ment re­sults. They mea­sure contact­less­ly and in­de­pendent of the sur­face fur­nish, shape and color of the ob­jects, mea­ning that the mea­su­red va­lues are not in­fluen­ced by these fac­tors. In ad­di­tion to the tried-​and-tested TCP/IP in­ter­face, the Ether­CAT in­dus­trial Ether­net in­ter­face is now also avai­lable for re­cor­ding and fur­ther pro­ces­sing the mea­su­re­ment data in real time. PNBC laser dis­pla­ce­ment sen­sors are the best in their class, whe­ther for thi­ck­ness mea­su­re­ment, dis­pla­ce­ment or dis­tance mea­su­re­ment.
PNBC se­ries mea­su­ring laser dis­tance sen­sors work with a high-​resolution CMOS line array. The state-​of-the-art ana­ly­sis me­thod of angle mea­su­re­ment cal­cu­lates the dis­tance to the ob­ject to be mea­su­red with mi­cro­me­ter pre­ci­sion. Laser dis­tance sen­sors are based on the tri­an­gu­la­tion prin­ciple and are ideal for high­ly ac­cu­rate mea­su­re­ments of dis­tances of up to 1,000 mm.

Real-​Time Data Com­mu­ni­ca­tion down to the Field­bus Level

There are va­rious op­tions for in­dus­trial data com­mu­ni­ca­tion. With our range of in­no­va­tive in­dus­trial Ether­net pro­ducts, we were the first sen­sor ma­nu­fac­tu­rer to make it pos­sible to send pro­cess and pa­ra­me­ter data from sen­sors and ac­tua­tors di­rect­ly to the control­ler. This gua­ran­tees conti­nuous data com­mu­ni­ca­tion in real-​time right on up to the field­bus level. With the PNBC se­ries, the data is trans­mit­ted via com­mu­ni­ca­tion chan­nels and connec­tions via Ether­net. Laser tri­an­gu­la­tion sen­sors offer ad­van­tages with the Ether­CAT in­dus­trial Ether­net in­ter­face. Es­pe­cial­ly in fast pro­cesses and when net­wor­king mul­tiple de­vices.

Ether­CAT for Pre­cise and Fast Ap­pli­ca­tions

Thanks to the di­rect data out­put, the mea­su­red va­lues are avai­lable in real time. The web ser­ver in­te­gra­ted in the sen­sors en­ables world­wide ac­cess to the de­vice’s own web­site for the res­pec­tive pro­duct. Pro­cess and pa­ra­me­ter data can be ac­ces­sed qui­ck­ly and ea­si­ly wi­thout ad­di­tio­nal soft­ware.

  • Ether­CAT com­mu­ni­ca­tion re­port for real-​time data
  • Pre­ven­ting ma­chine fai­lures through pre­dic­tive main­te­nance
  • Simple net­wor­king of the dis­tance sen­sors

High-​Precision Tri­an­gu­la­tion Sen­sors for All Chal­lenges

Mea­su­ring the Un­win­ding and Win­ding of Films on Rol­lers

Coa­ted, high-​gloss films are used to ma­nu­fac­ture bat­te­ries. In order to de­tect their level on win­ding de­vices, high-​precision laser dis­tance sen­sors mea­sure the exact dis­tance – re­gard­less of shape, color or sur­face. In this way, it is pre­ci­se­ly de­ter­mi­ned on the un­win­der how much ma­te­rial can still be un­wound; on the re­win­der, it is de­ter­mi­ned how much space there is avai­lable for ma­te­rial on the rol­ler. The film is wound or un­wound at a speed of up to 10 m/s for coa­ting. The mea­su­red va­lues are out­put via Ether­net in­ter­face and fur­ther pro­ces­sed.

Tilt Pro­tec­tion for Main­te­nance Ve­hicles for Ove­rhead Lines

Ove­rhead lines of rail net­works re­quire re­gu­lar main­te­nance. Spe­cial main­te­nance ve­hicles with lif­ting plat­forms are used for this pur­pose. To prevent ex­ces­sive til­ting or unin­ten­tio­nal tip­ping of the ve­hicle when the work plat­form is ex­ten­ded, four high-​precision laser dis­tance sen­sors per car­riage mea­sure the exact dis­tance from the ve­hicle to the rail head with pre­ci­sion in the low mi­cro­me­ter range. Equip­ped with laser class 2, the sen­sors de­tect the dis­tance to the track from a pro­tec­tive hou­sing. If a de­fi­ned to­le­rance value is ex­cee­ded, it is no lon­ger pos­sible to ex­tend the lif­ting plat­form.
