Analogue Tachographs


tachographsA tachograph is a device fitted to a vehicle that automatically records its speed and distance, together with the driver's activity selected from a choice of modes. The drive mode is activated automatically when the vehicle is in motion, and modern tachograph heads usually default to the other work mode upon coming to rest. The rest and availability modes can be manually selected by the driver whilst stationary.

A tachograph system comprises a sender unit mounted to the vehicle gearbox, the tachograph head and a recording medium. Tachograph heads are of either analogue or digital types. All relevant vehicles manufactured since 1 May 2006 must be fitted with digital tachograph heads. The recording medium for analogue heads are wax coated paper discs, and for digital heads are digital driver cards containing a microchip with flash memory. Digital driver cards store data as a .ddd file that can be imported into tachograph analysis software.

Drivers are legally required to accurately record their activities, retain the records and produce them on demand to transport authorities who are charged with enforcing regulations governing drivers' working hours.

Most tachographs produced prior to 1 May 2006 were of the analogue type. Later analogue tachograph head models are of a modular design, enabling the head to fit into a standard DIN slot in the vehicle dashboard. This would enable a relatively easy upgrade to the forthcoming digital models, that were manufactured to the same physical dimensions.

The analogue tachograph head uses styli to trace lines on a wax coated paper disc that rotates throughout the day, where one rotation encompasses a 24-hour period. If the disc is left in the head over 24 hours, a second trace will be written onto the first, and so on until the disc is removed. It is an infringement of EU Regulation 561/2006 to use a disc for a period longer than it is designed for. Multiple overlapping traces may still be deciphered in the speed and distance fields, but it is far more difficult for the activity field where one trace can easily be obliterated by another. Analogue tachograph heads provide no indication to the driver of the need to change the disc.

Analogue data is retrieved visually, and can be assisted by manual analysis tools. Analogue discs can also be electronically scanned and analysed by computer, although this analogue to digital conversion process still requires human expert interpretation for best results, due to imperfections in the source disc such as dirt and scratch marks in the wax surface that can be incorrectly read as trace marks.

Our purpose is to supply tachograph head units which are suitable for reconditioning. Tachographs available for delivery include various models by  VDO.We specialise in the supply of many rare, difficult to find tachographs. If you're having trouble trying to locate a particularly difficult to source tachograph.

Speed indication is by means of the electonicspeedometer or using an approved display functionalready integrated into the instrument cluster.












DLK Pro Inspection KeyVDO Tachograph Chart

Our VDO tachograph chart is an advanced storage medium, precisely manufactured to DIN ISO 9001.

Our VDO tachograph chart is an advanced storage medium, precisely manufactured to DIN ISO 9001. Three simple methods of chart analysis can be used: optical, electronic and microscopic.


Tachograph charts: records data of speed and distance traveled, as well as driver’s work and rest times (up to 2MB)
Electronic analysis: evaluation of driver’s charts using our KISCAN analysis software
Optical analysis: provides complete overview of all important data (i.e., speed, time groups, distance traveled).
Microscopic analysis: provides objective analysis of data, permissible in court.
