Acuity’s AR200 laser measurement sensors are ideal for demanding conditions

The AR200 laser displacement sensor by Acuity

Durham Instruments makes measurement solutions by Acuity available to the Canadian industrial market, such as the AR200 series of measurement sensors. The most compact laser displacement sensors available from Acuity, the AR200 line includes several models of triangulating laser devices covering metric measurement ranges from six to 100 millimetres (mm).

Ideal for demanding work conditions, the AR200 series comprises the only sensors of their kind with push-button selection of Analog, Limit Switch, and Serial output signals on standard models.

Laser spot gauges distance accurately

This lineup of laser displacement sensors is perfect for many applications, like water fabrication, automobile brakes, laser calipers, steel strip mills, and postal automation. Each instrument aims a Class 2 visible laser spot onto a target to gauge its distance accurately, and it can be programmed with serial commands through a PC desktop computer.

Acuity manufactures five models, all of which achieve a resolution of 0.03 per cent across their full measurement spans. Every unit has a range in mm that matches the model number. For instance, the AR200-50M can measure 50 mm to within 15 micrometres, and the AR200-6M can measure up to six mm.

Among the other possible options for these laser displacement sensors: a connectivity kit with terminal blocks, serial cable, and power supply; cables with optional lengths and polyurethane jackets; a software library; and a touch-panel display that can monitor up to two sensors for thickness measurements, with an RS485 output. Other technical specifications:

• Sample rates from two to 1,250 hertz, or sample on command
• Weight of 85 grams
• Operating temperature from zero to 60 degrees Celsius
• Standoff from 21 to 79 mm to middle of span
• Linearity from seven to 203.2 micrometres at plus or minus 0.2 per cent of span
• Resolution of nine to 30½ micrometres at plus or minus 0.03 per cent of span

The AR200 series is a popular choice in the forestry, medical, and high-technology industries. Durham Instruments also deems it suitable for use in general manufacturing, aerospace, automation, food processing, the military, mining, packaging, power generation, alternative energy, and transportation.
