AccuRange™ Laser Distance Sensor- The AR1000

The AR1000 laser distance meter is ideal for crane and hoist applications, position measurement, or for monitoring fill levels of bulk material. The unique sensor uses phase shift comparison measurement principles (of light) to accurately measure distances of 30 meters. Longer ranges to 150 meters are possible with the use of reflective target boards (3M Scotchlite 3279).

Typical speeds for the AR1000 laser distance sensor are 6 Hz, but 50 Hz sampling can be realized with white targets at close ranges with small target movements.

The sensor is designed for industrial environments with NEMA-4, IP65 enclosure ratings, permitting the sensor to be directly rinsed with water! Typical data outputs are serial RS232, RS422 (optional) and current loop 4-20 mA signals.

This sensor is highly versalite, able to measure distances both indoors and outdoors, but may have limitations to extremely dark targets or measuring through steam, fog and smoke where the signal is obstructed. However, the AR1000 measure to hot, glowing steel near 1000°C

A special AR1000H version is available with an internal heater, making the sensor suitable for operation to -40°C (-40°F). Users can configure the cycling of the heater through the serial interface.
