Description
The AccuRange 500 Laser Position Sensors are fast and accurate measurement devices for integrated industrial measurement systems. Available up to ranges of 1000 mm, all models use a compact enclosure. These sensors are available with optional BLUE laser diodes.
OVERVIEW
AR500 Laser Position Sensors use triangulation measurement principles to gauge distances to targets with great accuracy and speed. Fitting in the palm of your hand, the unit’s size is ideal for builders of compact machines and systems.
Laser position sensor models range from 5 to 1000 mm of measurement range and unlike the AR700 laser displacement sensors which have larger cases for longer ranges, all AR500 sensors share the identical case size.
How does this model differ from the AR200 and AR700 triangulation devices? The AR500 is similar in size to the AR200, but has longer ranges, up to 1000 mm. It is fast like the AR700 at 9400 Hz. The AR700 sensors are nearly five times more accurate than the AR500 models, but both can be ordered with configurable laser diodes.
The AR500 Laser Position Sensors are the only Acuity models available with optional blue laser diodes.
TECHNICAL DATA
The AccuRange 500 laser position sensor uses optical triangulation principles to accurately and quickly measure distances to targets. Available with many different diode options, the AR500 can measure to nearly any kind of target: dark, shiny, bright, opaque, translucent, etc.
HOW IT WORKS
A diode within the sensor projects a beam of visible (or optionally, infrared) laser light that creates a spot on a target surface. Reflected light from the surface is viewed from an angle by a digital CMOS line scan camera inside the AR500 sensor. The target’s displacement is computed from the image pixel data. The result is transmitted via serial or analog interfaces to a computer, display, PC or PLC.
MANY RANGES, ONE CASE SIZE
With nine different available measurement spans, the AR500 series measures from 5 to 1000 mm of displacement. Unlike the AR700 laser displacement sensors, all of these ranges use the identical, compact case size. Fitting in the palm of your hand, the AR500 rivals the tiniest of triangulation sensors available for industrial applications. The small enclosure means a very “sharp” beam path, permitting measurement down narrow tubes and small windows.
RED, BLUE OR IR LASERS
The AR500 comes standard with RED visible laser diodes. The shorter-range models require lower-powers and meet Class 2 laser requirements. The longer-range models are Class 3R and can be optionally ordered with high-power diodes at Class 3B for measuring black surfaces. As an option, all sensors can be ordered with different powers of 405 nm BLUE laser light. These models are idea for measuring to glowing-hot targets, polished metals and glass.
APPLICATIONS:
Engineers of automobile crash tests use the AR500 laser position sensor to measure the car’s deceleration during the crash event. Analog signals from the sensors are used to produce a deceleration curve plotted against time.
Laser Displacement Sensors and Confocal Displacement Sensors are ideal for any non-contact distance measuring applications. Choose them for high-speed measurements or when the target is too delicate or too hot for tactile probes.
Measuring the runout on cylinders is simple using laser displacement sensors. Align the laser path with the axis of rotation and collect your data at high speeds.
As circuit boards and the components on them shrink, the tools needed to inspect them must become more resolute. Lasers and confocal sensors have tiny measurement spots, allowing the inspection of the even tinier component features.
Laser sensors are commonly used in steel hot mills because they afford an accurate, non-contact method of determining the position or dimensions of materials that are too hot to touch. Many of Acuity’s customers are OEM integrators who service the specialized needs of Steel Mill customers.
There are many different applications in which laser sensors are used to measure and monitor the position of targets as they pass by a stationary sensor.
The high resolution and fast sampling speeds of Acuity’s laser displacement sensors make them versatile sensors for many industrial and research applications. Our laser triangulation sensors can be used in road profiling, battery profiling, rotary kiln profiling, and much more.
Thickness is the simplest dimension measured with non-contact sensors. If a material rests against a reference surface like a conveyor or table, one sensor is used to measure material thickness. Otherwise, dual opposing sensors measure materials that pass between.
