Vehicle sensors


Road sensor options

 

All these technologies are primarily vehicle sensors. They are not intended to detect people or animals, so may not be considered as safety devices.

Loop detectors       

Traditional road loops are multiple loops of wire laid in the wearing surface of the road. A detector module is connected to the loop. Vehicles entering the sensing area trigger the detector circuit. Detectors that remain activated while the vehicle remains may be considered for presence duty.

 

Single Point Vehicle Sensors

New devices now involve a single sensor set in the road wearing surface. The area of detection is defined by the sensitivity it is set to. Single point sensors are much quicker to install. Used ainly for activation, not presence.

 

Roadside Vehicle Sensors 

Sensors set off the road are simple to install, but less able to discern vehicles from other moving and stationary objects in the road.

 


Loop Detectors

 

Loops can be cut into solid road surfaces. Any breakup of the surface will tear the loop so be sure the surface is sound. The filler material should suit the road material. Loops can be pre-made in poly' pipe for burying in gravel drives.

Single point exit sensors

 

Loops can be cut into solid road surfaces. Any breakup of the surface will tear the loop so be sure the surface is sound. The filler material should suit the road material. Loops can be pre-made in poly' pipe for burying in gravel drives.

    Our Price £129.60 £108.00 Regular Price £162.00

    The VD955 can be used as either a safety loop or free exit probe detector. It should not be used as a safety loop if used with a Free Exit Probe. 

    The VD955 includes a VD.CI Interface board, to work with most gate automation control panels.
