Laser sensors offer range of duties

Sick UK says its new LMS500 family of laser sensors achieves new levels of high-speed and consistent performance in adverse highway 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,” said Tim Stokes, SICK UK laser sensor specialist. “These hard-working sensors ignore spray, smoke and dust and cope with rain, snow, ice and fog.

3316 Sick UK says its new LMS500 family of laser sensors achieves new levels of high-speed and consistent performance in adverse highway 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,” said 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 will operate reliably for applications such as vehicle spacing, speed and separation, load monitoring and automated tolls.”

Stokes said the LMS500 sensors can be quickly networked to synchronise multiple slave sensors useful, for example, when scanning vulnerable points of large installations such as toll booths.

The LMS500 is said to use a unique five-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 said to be detected offering greater security and safety.

LMS500 Series (Pro and Lite ranges) is said by Sick UK to offer customers a broad selection of models, resolutions and configurations to match application requirements and budgets. The sensors have a range of up to 80 metres, with a 1900 field and 100Hz scanning frequency said to enable rapid detection and evaluation.

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 10 programmable fields per unit; an Ethernet interface and USB connections meet connectivity and configuration requirements. Power offtake is also said to be low.

“SICK introduced the world’s first 2D laser scanner,” added Stokes. “It started the laser sensor revolution that enabled customers in all sorts of industries to achieve new productivity and security. Now the LMS500 elevates scanning technology to a new level of speed, accuracy and consistent availability.”

    AGD Systems has increased the zone of detection for its 645 pedestrian detector, the AGD 645. The 645 used to offer a 5m x 3m detection zone. Now, the optical kerbside detector covers a 10m x 3m zone in standard build format. This is to monitor the new super-crossings that are increasingly deployed internationally, said Ian Hind, AGD’s commercial director. “We are seeing this already in many locations worldwide, particularly at modal intersections such as bus and rail stations, as well as in busy city cen

    The latest technology continues to improve the quality of concrete paving while contractors are also benefiting from more adaptable equipment - Mike Woof reports For many concrete paving applications, versatility is required rather than a high production rate. Leading paver manufacturers such as GOMACO, Power Curbers, Terex and Wirtgen all offer high mobility machines that can be adjusted to cope with an array of tasks. For a contractor, the advantage of these smaller pavers is that they can be configured q

    A sustainably good road surface often depends on how well understood is the ground underneath the road’s route. Brian Jones* offers some best practice and advice for getting the most from ground-penetrating radar investigations Ground-penetrating radar (GPR) is one of the most accurate non-destructive testing (NDT) methods available. To get the most from GPR surveying, it is absolutely essential to understand how GPR tools work and follow best practices when conducting surveys. Key areas to be aware o
