measure the distance to or presence of atarget object or material through air without touching it. The measureddistance is provided as an output in a variety ofstandard electrical interfaces compatible with displays,machinery, PLCâs, computers and most electronic or electrical machinery.
Non-contact Contactless sensors have distinct advantages in challenging environments wherecorrosive, scaling, coating, or dirty materials are likely to negatively impactthe performance and maintenance costs of contact sensors. Non-contactContactless sensors are also desirablewhere the material being measured cannot be corrupted by contact with anymeasuring device.
1. Industries monitor liquidlevels in tanks, vats, drums, bins, lift stations, flumes, weirs and stillingtubes. Environmental monitoring applications measure the ocean surface forTsunami warnings, river & stream levels for flood warnings and irrigationchannels and ponds for water delivery. Where there is liquid there isusually a need for inventory or level control.
2. Objects can be detectedfor security, counting, inventory or robotic obstacle avoidance. Contactless sensors are not affected by the objectâs coloror optical characteristics such as reflectivity, transparency or opacity.People can be detected at kiosks, or determined to be approaching or leaving.Targets can be monitored over the full sensor range or restricted withinuser-defined distance ranges.
3. DISTANCERANGING & DIMENSIONING â measuring location
Supreme sensors can discriminate objects by height or size, such as whenselecting and routing boxes on a conveyor or rejecting out-of-dimensionobjects. Converting machines measure
