Acuity laser distance sensor – AccuRange™ 1000

Acuity's AccuRange 1000 laser distance sensors are very unique distance measuring devices capable of measuring up to 30m to regular surfaces and up to 150 m to special reflectors. They employ a “phase-shift comparison” measurement principle that leads to very accurate distance measurements. This LIDAR technology uses high frequency amplitude modulation with continuous wave laser diodes. The AR1000 measures the phase shift of up to five frequencies of emitted light to accurately gage the distance to a target.

For very distant measurements beyond 30 meters, one can use reflective target material to measure up to 150 meters. The AR1000 has a Class 2 visible laser diode for simple aiming and setup. The laser beam spot size is 5 mm with low divergence. Typical sample output rates are 6 Hz. 50 Hz sampling is possible at close ranges to white targets.

This measurement sensor comes standard with a RS232 serial interface for communication with a PC computer or PLC. Also standard is a 4-20 mA current loop output and a single Limit switch for indicating alarms. This can be useful for triggering an external device when a target reaches a set position. The AR1000 can automatically sample distances or receive an external trigger for a single distance measurement. As an option, the AR1000 can be ordered with RS422 (replaces RS232), SSI or Profibus outputs.

This versatile laser distance sensor is ideal for positioning overhead bridge cranes, silo fill height measurements, length measurements, vehicle positioning or monitoring the linear displacement of any opaque target surface. Call Acuity and let us help you solve your measurement applications!
