Xtralis ASIM IR240 Series Multi-Purpose Dynamic Detectors

Product Information

Dynamic PIR Detection

Dynamic PIR detectors discriminate between slightest changes in thermal radiation caused by movement of vehicles or people in their fi eld of view. Their differential sensor and amplifi er reliably detects any kind of target while disregarding slow temperature changes of the road surface caused by the weather. Narrow zone and volumetric detection patterns are available.

Applications

Detection of vehicles or pedestrians for the time there is movement in the field of view for

to optimise traffic fl ow by controlling traffi c dependent signal installations.

The detectors are typically mounted on top of a signal head, a gantry or a bridge and aimed to face the approaching traffic or cover a pedestrian crossing.

The output will be activated as long as movement is detected in the field of view.

Model IR 248 can be used for detection of pedestrians. It is also used in mobile traffi c signal installations where a precise alignment can not necessarily be granted.

Technical Features

The detectors of the IR 240 Series have rugged metal housings for use in the harshest climatic conditions. Their small size reduces the chance of vandalism.

A standard mounting bracket is supplied for quick, stable and easy installation. The detectors of the IR 240 Series have originally been designed for mobile, solar powered systems but are equally well suited for fixed installations with DC power supply.

They are easy to set up and align even by unskilled persons and built to withstand the rough handling conditions expected in road works environments.
