SICK's LMS500 laser sensor performs whatever the conditions

19 July 2012

Sick UK's new LMS500 family of laser sensors achieve consistent high performance in adverse conditions, delivering reliable moving object detection and distance measurement even in the the most challenging of environments. New sensing and signal processing technology has been developed for the LMS500 enabling it to achieve high-speed, accurate performance and high availability even in bad weather or low-visibility conditions.

“The incontrovertible rule in laser measurement used to be – if you can’t see it, the laser can’t see it, but with the LMS500 this is no longer true,” explains Tim Stokes, SICK (UK) laser sensor specialist. “These hard-working sensors ignore spray, smoke and dust and cope with rain, snow, ice and fog.  They operate harbour-side or in heavy industry, in mines, on buildings or highways in the toughest environments.”

The LMS500 uses a novel 5-echo technology, combined with a very small radius (3.6mrad) spot, to ignore irrelevant signals that would distract sensors of lower capability. With five echoes per pulse, multiple objects at different distances in the field are also detected offering greater security and safety.

The LMS500 sensors can be quickly networked to synchronise multiple slave sensors, for example managing freight yards, or scanning entrances, windows and vulnerable points of large building facades or high-security compounds.

LMS500 Series (Pro and Lite ranges) offer customers a broad selection of models, resolutions and configurations to match application requirements and budgets. The sensors have a range of up to 80m, with a 190 degree field and 100Hz scanning frequency which enable rapid detection and evaluation in applications such as building security or anti-collision. 

The sensors have an IP67-protected modular design and a built-in heater. The multiple I/Os and powerful software platform combine self-monitoring and auto-calibration with up to ten programmable fields per unit; an Ethernet interface and USB connections meet connectivity and configuration requirements. Power offtake is low.
