The AR3000

distance measurement sensor is Acuity's longest-range model for cranes, process mointoring and fill levels in containers and silos. Its eye-safe laser and robust enclosure design make it a versatile choice for industrial measuring applications. A special version of the AR3000 can be used as a laser altimeter.

AR3000 Distance Measurement Sensor Principles of Operation
The AR3000 sensor is a time-of-flight sensor that measures distance by a rapidly-modulated and collimated laser beam that creates a spot on a target surface. Components of the reflected light signal are collected by a lens and focused onto a photodiode within the sensor unit. The reflected light returns with a shift in phase compared with the reference signal. From the amount of phase shift, a required distance is calculated with good accuracy. The distance is transmitted through serial communications or analog outputs. The device monitors the distance to (and speed of) objects in motion. The standard model has a range of 300 m to natural surfaces with 90% reflectance and to 3 km to special reflectors. A visible sighting laser beam is used to aim the sensor. An AR3000 version with a wider laser divergence measures to 0-50m for closer-range measurements to targets of lower reflectivity..
