Description
The LVU30A Series of CE andRoHS compliant low-cost ultrasonicsensors produce detectionranges from as close as 178 mm(7") to greater than 4 m (13').Incorporating enhanced state-of-the-art ultrasonic technology, thesensors provide precision non-contactdistance measurement forfactory automation or industrialprocess control. The LVU30A sensors standout over all othersystems because of theiraffordability, extraordinary ease ofoperation, genuinely user-friendlysoftware, versatility in user-controlledoutputs, and the abilityto be set up without using a target.They transmit narrow beam soundpulses at a user-selected rate(software triggered), the processreturns echoes, and various outputsdepending on the position of thetarget and programming parameters.Specifications
