AR700 Laser Displacement Sensor

AR700 Laser Displacement Sensor

Acuity introduces the AR700 series of laser displacement gauges for measuring position and object dimensions. Built on a decade of success with the predecessor AR600 laser sensor, industry users demanded faster and more accurate non-contact metrology equipment. The AccuRange 700 boasts output speeds to 9400 Hz and resolutions (model dependent) as low as one sixth of a micrometer. The unit is very compact, measuring approximately 1 x 2 x 3″ (25 x 50 x 75 mm), almost 80% smaller than its AR600 predecessor.

This Acuity digital sensor has selectable speeds up to 9400 Hz (when using 3-Byte Binary Data format). Don’t be fooled by competitor’s claims of higher speeds. Acuity laser distance sensors are unique and our specifications are straightforward. The device will in fact output 9400 distance readings in a single second. This is unlike our competitors who often quote the maximum sampling rate of their detector. This number is not real because the user will never see data output rates that high through serial or analog interfaces or the cumbersome controllers that are required to operate their sensor heads.

A special Trigger Mode permits users to initiate sampling via serial command or discrete hardware triggers. This trigger can be used for synchronizing multiple sensors. The maximum speed using the hardware trigger is reduced to 4500 Hz.

Optics and digital detectors have improved greatly over time and Acuity’s AR700 laser displacement sensor offers a three-fold improvement of resolution over its previous model. Resolution is the smallest increment of distance that can be detected by the distance gauge. AR700 sensors specify a 0.005% (of the measurement span) resolution for all models in this series. Resolutions are measured on targets of 85% diffuse reflectance (white) and in static conditions. Contact us if you have any questions about our specifications.

Compact size
Measuring approximately under 8 cubic inches, this unit is ultra compact because it houses all electronics for measuring. No external controller or amplifier needed. Each sensor includes the sensor head and 6 feet (2 m) of cable. Note that longer-range sensors have longer mechanical enclosures.
