Acuity's AR600 displacement sensor is among the most accurate optical devices in the field. The shortest-range models are capable of micron measurements at sampling rates to 1250 Hz. This Acuity laser displacement sensor is unique and has the ability to accurately measure to difficult target materials. The product is patented by the US Patent and Trademark Office (patent 6,624,899, Triangulation Displacement Sensor). Acuity sensors are designed for high-demand industrial applications. Each laser displacement sensor is NEMA-4 (IP67) rated and can withstand mist and spray. However, as with all optical devices, it is necessary to keep the sensor window obstruction-free. The effects of a dirty sensor window are similar to dirty eyeglasses for people: it can not see clearly. As a result, measurement accuracy can decrease.

AR200 / AR600 laser sensor demonstration Software
This software is used to quickly and easily setup your AR200 and AR600 laser measuring sensors. The graphical user interface makes it simple to configure the settings. Acuity demo software requires the download of the version release zip file as well as the National Instruments™ Visa. To install the demo software, run setup.exe. After this, install the visa300runtime.exe file.

Output interfaces

Standard RS-232 Serial Output
All sensors come with an RS-232 serial output on a 6 foot, 9 pin (D sub 9) cable that connects directly to PC style serial ports. Serial output can be configured for one of several data formats. ASCII may be used for visual reading with a terminal device or emulation program, or a binary format can be used with application software. The data may include calibrated distance output only, uncalibrated range and other sample data only, or both. When the binary format uncalibrated distance output only is selected, the maximum sample rate is 1250 samples per second. Baud rate is selectable from 300 to 56,000 baud.

Optional RS-422 Serial Output
For long distance communications up to 4000 feet, the RS-232 serial output may be replaced with an RS-422 serial output. The available sample rates, formats and software configuration commands are all the same as for the RS-232.

Optional Current Loop Output
A 4-20 milliamp current output may be ordered as an option for the AR600 sensor. It is installed internally. The resolution is 1 in 4000 and the integral linearity is 1 in 2000. The zero and span points for the current loop output may be set at any location. The span point (20 mA) may be made closer than the zero point if desired. The calibrated output on the current loop allows sample rates of 1250 samples per second.The 4-20 mA output has a maximum voltage capability of 10 volts, and it is suggested that a 400 to 500 ohm load be used at the reading instrumentation for best accuracy
