3.7 Sensors
The sensors of the RAV TD8060TWS/TWSR and RAV TD8080TWS/TWSR unit require no
cable connections for angle measurement. The measurement units consist of infra-red data
transceivers and CCD type transducers with infra-red emission focal point.
All the characteristic angles of both vehicle axles are controlled by CCD sensors (6 sensors
for the TD8060TWS/TWSR serie and 8 sensors for TD8080TWS/TWSR serie) and infra-red
transmission.
Data transmission between the infra-red sensors is effective even in critical lighting
conditions.
Data transmission of the front measuring heads is VIA RADIO by means of modules
housed inside the front measuring heads and the console.
The rear sensors do not communicate directly with the console. Their data are
transmitted/received through the infra-red transmission of the front sensors [see para. 3.7.3
on page 10).
Power is supplied by rechargeable 6V long-life batteries; recharging of front and rear
measuring heads is done through the supports for recharging the batteries of the measuring
heads located on the console.
For all the sensors featuring rechargeable batteries, the power and consumption data are as
follows:
REAR HEADS TD8060TWS/TWSR TD8080TWS/TWSR
FRONT HEADS 8060TWS/TWSR
