Acuity offers a variety of long range sensors for accurate, non-contact measuring. These distance measurement lasers utilize pulsed time-of-flight measurement principles to accurately measure distances up to 300 meters on natural surfaces (up to 3,000 meters with retro-reflective tape). These distance measurement sensors such as the AR3000 are highly versatile, being able to measure distances both indoors and outdoors. Applications include, but are not limited to, load confirmation, alignment, lumber positioning, crane monitoring, fill level measurement, velocity measurement and altitude measurement.
Our distance measurement sensors differentiate themselves based on ruggedness, compactness, distance range with retroreflective targets, as well as light tolerance. High-sampling rates, ability to work in industrial conditions and laser rangefinder sensors with eye-safe technology are other distinguishing features of our distance sensors. Whether your application calls for a rugged sensor, an ultra-compact sensor, or a light-tolerant sensor, Acuity’s distance measuring sensors are up for the task.

The Acuity AR1000 laser distance sensor can measure up to 30 meters on natural targets and up to 150 meters with a retroreflective target with an accuracy of ± 3 mm. This rugged sensor is built for tough, industrial environments and applications such as fill level measurement and material height monitoring.
The Acuity AS1100 Long Distance Sensor can measure up to 100 meters on natural targets and up to 150 meters away with an Acuity reflective plate with an accuracy of ± 3 mm. This rugged sensor is built for versatile environments and is often used in applications that involve measurements on hot materials.
The AS2100 is a highly accurate laser distance sensor that is designed to work well outdoors, in bright lights, and even on difficult targets such as hot or dark surfaces. With the ability to take accurate measurements (± 1 mm) from distances up to 500 meters away, and a measurement frequency of up to 250 Hz, it is the perfect laser for a wide range of applications.
Acuity Laser’s ultra-compact rangefinder model. This eye-safe rangefinder has a measurement frequency of up to 40 kHz and can measure distances to natural targets up to 70 meters away or to retroreflective targets 270 meters away. This laser is best for applications that demand high sampling rates.
