Maintaining correct tyre pressure on a
vehicle is important for a number of reasons, if a tyre is
under inflated, tyre life will be reduced by over 50%, fuel
economy can be reduced by as much as 10%, and braking performance
will be reduced by approximately 20%. This is obviously important
to all road users for safety reasons but to businesses involved
in transportation of any form of goods, materials or people;
ensuring tyre pressure is correct is also important to reduce
running costs of their vehicles.
With the development of wireless technology,
a number of hi-tech, wireless digital tyre pressure monitors
have been developed providing real-time data on the state
of all the vehicles tyres even when in motion. Sensors either
fit onto the valves of each tyre or can be internally wheel
mounted, these sensors incorporate radio transmitters which
transmit the data to a receiver unit which often has a display
situated on the dashboard of the vehicle.
The receiver/display units generally
run from a 12V DC power supply (often connected to the car's
battery) with the sensors using batteries to power them. These
units need to be compact, lightweight, reliable, and be able
to operate for extended periods in harsh conditions, this
specification links in with that of the battery used to power
the sensors. The Sonnenschein and Tadiran product range offers
a number of cells to meet such requirements in small sizes
including BEL, 1/10D and 1/6D size cells. These cells have
a high voltage and capacity ratings along with a wide operating
temperature range with lightweight robust construction.
