The Acuity AR100 laser displacement sensor

Acuity test and measurement solutions are available from Durham Instruments, such as the ultra-compact AR100 laser displacement sensor. Among the smallest of its kind, this device comes with ranges from ten to 500 millimetres (mm) in just one case size, making it perfect for high-performance applications with tight size and mass budgets. The AR100 has a linearity of plus or minus 0.05 per cent of the measurement range of most similar devices, and it can take 9,400 measurements a second.

Long ranges, high accuracy

This compact laser triangulation sensor weights only 40 grams without its cable and measures a mere 17 by 45 by 30½ mm, with six ranges available – ten, 25, 50, 100, 250, and 500 mm. With recent innovations in detectors and miniaturized optics, the Acuity AR100 is a rare triangulation laser with long ranges and high accuracy. The 500-mm model offers 0.1 per cent linearity and 0.02 per cent resolution over the full measurement range, and the other models have 0.05 per cent linearity and 0.01 per cent resolution. Speed is not sacrificed, with a 9.4-kilohertz maximum sampling rate.

The AR100 comes with a Class 2 eye-safe laser in red or blue. At 660 nanometres, the red laser functions well for most tasks and is less expensive, while the blue option, at 405 nanometres, is more appropriate for targets that absorb or emit too much red light. All Acuity laser sensors operate based off non-contact measurement, and the AR100 enclosure can handle dusty environments and occasional splashes, as its IP67 rating denotes.

The user can choose a standard RS232 or optional RS285 serial interface to communicate with a computer or PLC. The AR100 also comes with an analog output, with a choice between 4-20mA or zero to ten volts. The sensor has a limit output for indicating alarms, which is useful for triggering external devices when targets reach set positions.

The AR100 sensor is a versatile product, and Durham Instruments recommends it highly for use in the general manufacturing, aerospace, automation, food-processing, forestry, medical, military, mining, packaging, power-generation, and transportation sectors.
