U2GT Ultrasonic Sensors: The Solution for Hygiene and Washdown Areas

The new full-​metal ul­tra­so­nic sen­sors in a high-​grade stain­less steel housing are ex­tre­me­ly ro­bust with a hy­gie­nic de­sign. The hy­gie­ne sen­sors are op­ti­mi­zed for mea­su­re­ment and de­tec­tion tasks and are used both in the hy­gie­ne area and in the wa­sh­down area.

Ul­tra­so­nic sen­sors ope­ra­te ac­cor­ding to the bat prin­ciple: They emit a short sonic pulse and mea­su­re the time until an echo si­gnal ar­ri­ves. The sen­sors are in­sen­si­ti­ve to con­ta­mi­na­ti­on and en­vi­ron­men­tal in­flu­en­ces thanks to the con­tact­less ul­tra­so­nic mea­su­ring prin­ciple. In con­junc­tion with the ro­bust stain­less steel ver­si­on, the range of up to 1,300 mm and the stan­dar­di­zed com­mu­ni­ca­ti­on in­ter­faces, the ul­tra­so­nic full metal sen­sors set new stan­dards. Ul­tra­so­nic full-​metal sen­sors have been spe­cial­ly de­ve­lo­ped to ful­fill the re­qui­re­ments of the phar­maceu­ti­cal, food and che­mi­cal in­dus­tries. Thanks to the in­te­gra­ted IO-​Link in­ter­face and the va­rious out­put types, the ul­tra­so­nic all-​metal sen­sors offer the grea­test pos­si­ble fle­xi­bi­li­ty in pa­ra­me­te­riza­ti­on and con­fi­gu­ra­ti­on.

CE Mark

The CE mark is the ma­nu­fac­tu­rer’s de­cla­ra­ti­on that the mark­ed pro­duct com­plies with the stan­dards and di­rec­ti­ves of the Eu­rope­an Com­mu­ni­ty. Pro­ducts bea­ring the CE mark may be mar­ke­ted in the EU. 

UKCA Mark

The UKCA mark is the Bri­tish pro­duct mark re­qui­red for cer­tain pro­ducts that are mar­ke­ted in Great Bri­tain (Eng­land, Wales, Scot­land). 

cUL Lis­ted

The tes­ted pro­ducts with the UL mark are tes­ted against ele­va­ted tem­pe­ra­tu­res, im­mersi­on in water, high hu­mi­di­ty, wea­the­ring, clea­ning/sol­vents, oil, ga­so­li­ne, me­cha­ni­cal loads or lu­b­ri­cants. cUL lis­ted pro­ducts can be sold on the Ca­na­di­an and US mar­kets. 

ECO­LAB® Cer­ti­fi­ca­ti­on

The ECO­LAB® cer­ti­fi­ca­ti­on is is­su­ed for pro­ducts used in the food in­dus­try and are re­sistant to spe­ci­fic che­mi­cals.

Through-​Beam Sen­sor

Full-​Metal Ul­tra­so­nic Sen­sors for De­man­ding Hy­gie­ne and Wa­sh­down Re­qui­re­ments

De­tec­tion of Food on Con­veyor Belts with Hy­gie­nic Ul­tra­so­nic Di­s­tance Sen­sor

When packa­ging foods such as ham, cheese, fish or bacon, the ob­jects por­tio­ned into sli­ces are trans­por­ted on con­veyor belts and first wrap­ped in paper. To en­su­re that the paper is pla­ced at the right mo­ment, an ul­tra­so­nic sen­sor must first re­lia­b­ly de­tect the in­co­ming food despi­te dif­fe­rent co­lors, sha­pes and sur­faces. The sen­sor in the hy­gie­nic stain­less steel housing is moun­ted above the con­veyor line. Thanks to IP69K pro­tec­tion, high-​pressure clea­ning (up to 100 bar) at a water tem­pe­ra­tu­re of 80 °C and with ag­gres­si­ve clea­ning agents is pos­si­ble.

Fill-​Level Mea­su­re­ment of Spi­ces in Fro­zen Pizza Pro­duc­tion via Ul­tra­so­nic Sen­sor

Fro­zen piz­zas are pro­du­ced and the top­pings added in high­ly au­to­ma­ted pro­duc­tion fa­ci­li­ties. Spi­ces such as ore­ga­no are sprinkled on top of the piz­zas after the top­pings have been added. The spice mix­tu­re is lo­ca­ted in an open con­tai­ner di­rect­ly above the con­veyor belt. An ul­tra­so­nic di­s­tance sen­sor in a hy­gie­nic stain­less steel housing mo­ni­tors the con­tai­ner to de­tect the exact fill level at all times so the con­tai­ner can be re­fil­led in good time. The level can be con­ti­nuous­ly mo­ni­to­red thanks to the ana­log out­put.
