Sick has launched the LMS1000 and MRS1000 infrared LiDAR sensors, aiming to deliver more accurate and reliable distance sensing and measurement, especially in difficult environmental conditions.
The sensors, which are suitable for indoor or outdoor use, weigh 1.2 kg and can be factory-fitted or retrofitted to existing equipment.
They can be mounted on machinery and gantries or on walls, above entrances or anywhere convenient for optimum viewpoint.
Aiming to deliver strong performance in sub-optimal weather, the units feature high definition distance measurement (HDDM+) ‘triple-echo’ scanning technology.
Heavy rain, snow, mist and dust can cause false signals if inferior LiDAR sensors or alternative technologies are used, noted a statement from Sick.
Neil Sandhu, Sick’s national product manager of imaging, measurement, ranging and systems, said: “The triple-echo technology gives the operator greater confidence in the reliability of the information from the sensor, even under difficult environmental conditions. As false signals are almost eliminated, there is much less risk of collisions or errors due to an inaccurate evaluation of the position of objects in the sensor’s field.”
The LMS1000 is designed as an “easy-to-use” sensor, scanning in a single plane with a 275° angle of view, up to 64 m for a general range of distance detection and ranging applications, with 10 fields allowing several different pre-programmed applications.
With the same angle of view and distance, the MRS1000 scans in four planes at different heights, allowing either the height of objects to be scanned in, such as overhanging obstructions, or in-depth mapping using the sensor from an elevated position.
This enables it to be used for more complex tasks such as stacked container parks, multi-level obstructions and security for large or sensitive areas.
The triple echo evaluation technology means the masking effects of snow fall, mist, rain or dust are eliminated from the signal while the units have an operating temperature range of -30°C to +50°C.
