The long distance displacement measurement sensor AR3000 is distributed in Australia and in New Zealand by Bestech Australia .

Acuity, USA, has introduced the AR3000 laser distance and speed measurement sensor for extremely long-distance applications of up to 3km for monitoring the position of targets and objects. This sensor can measure 300meters to natural surfaces with 90% reflectance. Longer ranges to 3000meters are possible with the use of reflective target boards. A visible sighting laser beam is used to aim the sensor. In special modes, it reports instantaneous or continuous speed measurements.

This Acuity product has been adopted in many applications including the metal industries, seaports and military applications. Typical applications for the AR3000 distance measurement sensor include bridge crane monitoring, trolley positioning and altitude measurement amongst others.
The laser distance sensor uses pulsed time of flight principle to achieve measuring speeds to 2KHz. This displacement sensor measures distance by a rapidly-modulated and collimated laser beam that creates a spot on a target surface. The phase shift of the reflected light compared to a reference signal is measured with high accuracy. This laser displacement device has a resolution of 1mm and an accuracy of +/-20mm.

This distance measurement sensor is an eye-safe (Class I) infrared laser device with an on-board visible aiming pilot laser (Class 2) that can be manually turned on and off. The sensor is designed for industrial environments with NEMA-4, IP67 enclosure ratings, permitting the sensor to be used in dusty and wet industrial environments, either indoors or outdoors. The device's compact design allows it to be placed in tight spaces. The sensor's on board heater prevents the front optics from fogging and icing.

The main features of AR3000 long distance measurement sensors are:

  • Range: 0.5 to 300m (targets of 90% diffuse reflectance)
  • 3000m max (retro reflective targets)
  • Resolution: 1mm
  • Accuracy: Up to ±20mm
  • Output: Standard 4-20mA/ RS232/ Limit switch or Optional Profibus/ SSI output.
  • Environmental: NEMA-4, IP67.
  • Weight: 800 grams (without cable)
