Triangulation Laser Displacement Sensors
When choosing a laser displacement sensor, it is important to have the knowledge of what needs to be measured, the accuracy required and the speed required for the laser displacement sensor. Slentech provides Laser Triangulation Sensors (Short Range Lasers) from Acuity with a measuring range from 3-1300 mm in Australia, New Zealand and Oceania.
AR100 Super Compact Laser Triangulation Sensor
The AR100 is one of the smallest laser measurement sensors in the world. The ultra-compact AR100 comes with ranges from 10mm to 500mm with a single case size. It can take 9,400 measurements per second and has a linearity of ± 0.05% of the full measurement range for most models. In short, the AR100 is perfect for applications with tight size and mass budgets that can’t sacrifice performance.
Engine Vibration Measurement; Acuity’s AR100 and AR200 compact laser triangulation sensors are commonly used to monitor and calculate the vibration created by an engine in testing labs. Our cost effective sensors are placed at various sections of the engine to measure the vibration displacement in multiple engine locations. Laser measurement of engine vibration is preferred over other types of measurement because it is completely non-contact. That allows you to install the sensors away from the engine. Devices such as accelerometers need to be attached to the vibrating parts, and that extra mass affects the vibration measurement, making data less accurate. Acuity lasers are extremely precise, and they can give you the accuracy you need without affecting the results. Acuity’s AR100 is a common sensor used for this application because of its fast, 9.4kHz sampling rate, compact size, and precision at a cost-effective price.
Lumber Thickness and Dimensions; The forest, lumber and wood products industry is a regular user of Acuity laser sensor products for the measuring of logs, cants, lumber, veneer thickness, paperboard, etc. AR700 laser displacement sensors are commonly integrated into automated lumber finishing machines to measure board position, board dimensions, thickness measurement and surface profiles. The long-distance AR100 laser triangulation sensor offers a valuable stand-off distance, keeping the measuring equipment away from the quickly moving lumber and potential hazards.
Paper Roll Diameter; Acuity laser sensors are used in the paper industry to measure the diameter of paper rolls to determine the amount of material present. As a very large roll of paper winds off to smaller individual rolls, manufacturers must ensure that the smaller rolls have enough material present to be able to sell. When selecting a measurement sensor tool, paper manufactures demand two things. The measurement tool must have enough range to fully measure the wind up distance of the roll and have a small enough resolution to determine one additional layer of material. Acuity’s AR100 laser triangulation sensor is well suited for this type of measurement. The AR100-500 model has a 500 mm (~20 in.) range and boasts a resolution of 0.02% of the measurement range. The sensor’s fast, 9.4kHz sampling rate, compact size, and precision at a cost-effective price, provide a quality sensor for this application.

Acuity AR500 Laser Position Sensors are used to collect data of vehicle deformation, acceleration, temperature, etc. at high speed. This information is then analysed to determine avenues for improvement in safety.
Laser Ride Height Sensor; Automotive companies must ensure their systems operate at peak performance. Whether it be for vibration, suspension, or any other displacement measurement, the automotive industry demands precise measurement for quality control and testing. When it comes to vehicle dynamics, providing precise ride height measurement from the vehicle to the ground is critical for testing different variables under one measurement. One technique is to use non-contact displacement sensors. Displacement sensors can be placed anywhere throughout the car to provide real time feedback of the parameters of the car. Acuity’s AR500 line of laser position sensors are commonly used to measure the overall ride height of a car. Our AR500 sensors are built to withstand harsh conditions while monitoring the distance from the vehicle to the ground level. The AR500 ride height laser is a compact, metal housed sensor that is capable of measuring up to 1000mm.
