Acuity AR1000 laser distance sensor

Thursday, 01 July, 2021 | Supplied by: Slentech Pty Ltd

The Acuity AR1000 measures targets from 0.1 up to 30 m without the use of reflective targets. It can work with opaque targets, even glowing steel at temperatures up to 1000°C. The accuracy is typically ±3 mm, depending on the reflectivity of target surface, ambient light and temperature conditions.

In simple sampling modes, the AR1000 automatically determines the optimal sampling speed, waiting until it collects enough light to make an accurate measurement. Typical sampling output rates are 6 Hz, but 50 Hz sampling is possible for short ranges and white targets. For long-distance measurements, a larger target with a retroreflective target material can be used to increase the maximum measurement range to 150 m. The AR1000 has a Class 2, red visible laser diode for simple aiming and setup. The spot size is 5 mm as the light leaves the laser, and the beam has a divergence of 0.6 milliradians.

A standard RS232 or optional RS422 serial interface is available for communication with a computer or PLC. The AR1000 also comes with a standard 4–20 mA analog output. The analog output can be programmed to have a custom measurement span, and the minimum and maximum currents can be set to any points in the laser’s range. The AR1000 has a single limit output for indicating alarms that can be useful for triggering an external device when a target reaches a set position.
