产品描述

The LVU30 Series of RoHS Compliant low-cost ultrasonic sensors that produce detection ranges from as close as 178 mm (7") to greater than 4.5 m (15'). Incorporating state-of-the-art ultrasonic technology, the sensors provide precision non-contact distance measurement for factory automation or industrial process control. The LVU30 series of sensors stand out over all other systems because of their affordability, extraordinary ease of operation, genuinely user-friendly software, versatility in usercontrolled outputs, and the ability to be set up without using a target. They transmit narrow beam sound pulses at a user-selected rate (software triggered), the process returns echoes, and various outputs depending on the position of the target and programming parameters.
