Acuity’s AR2700 high-speed long range sensor uses time-of-flight measurement principles to measure long distances at short measurement intervals to provide precise accuracy at high sampling rates. The ultra-compact AR2700 laser sensor can measure distances from 0.2 m to 70 m to natural targets of low reflectance (10%). The accuracy is generally specified with an absolute linearity of +/- 60 mm and a repeatability of +/- 25 mm. The AR2700 linearity will vary depending on sample averaging, temperature, and surface reflectivity of the target surface. The sensor has maximum sampling rate of 40,000 samples per second and measurements can be triggered using an input signal wire or a serial command at rates up to 30Khz. For very distant measurements, you can use retroreflective target material (such as 3M Scotch lite 3000X) to increase the maximum range to 270 meters. The compact laser distance sensor is offered as a ready-to-use device with industry standard IP67 housing. Typical applications for the AR2700 include bridge crane monitoring, trolley positioning and altitude measurements, height pole measurement, amongst others. Its high sampling rate and ultra-compact case make it ideal for industrial scanning applications and OEM installations with a tight fit.
