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.
