Kimax 2 radio fits your DIN slots

And offer you a load control of you vehicle, either as a solo instrument including build in air sensors and interface for SG Sensors, or as a display unit only, which needs contact to one or more Kimax 2 Sensors through the
power line device bus, which can act on the existing electrical system on your vehicle.

  • Kimax 2 calculates the current loads from the current air pressure in the suspension system and displays this figure as a three-digit value.
  • The Kimax 2 On-Board Load Control is an electronic weighing system which can be used in all vehicles whose axles or axle groups are equipped either with air suspension system or steel spring suspension system.
  • Due to the modular construction, the product is very flexible and can be individually adapted to most vehicle conditions.

… and warns when limits are exceeded

Kimax 2 has two separately adjustable alarm levels. Exceeding alarm level 1 is indicated by a flashing diode for the individual axle which has exceeded its limit.
Alarm 2 switches in an internal electronic “relay” when the total weight for the vehicle is exceeded. The relay signal can be used as ON/OFF input for another unit, for example a tracking GPS or a tachograph.
Kimax 2 helps to achieve economical transportation, avoids fines and simultaneously optimizes the cargo weight.


* Tractor/trailer readings call for a Kimax 2 radio installed in the truck and a Kimax 2 sensor installed on the trailer.

Axle load measurement

Kimax 2 uses the linearity between strain in the front axle and the load above the axle.

For the rear axle group Kimax 2 uses the linearity between air pressure and load abovethe axle.

By using two reference points for each axle (empty weight and weight at maximum load) and the currently measured strain/air pressure, Kimax 2 calculate the current axle load with an accuracy of 2% of the maximum load for each axle.

Basic operation

The strain in the front axle will increase linearly with the load above the axle.

Depending on load of the vehicle, the level valve(s) maintain a constant height of the chassis above the ground surface by regulating the pressure in the air bellows.

Kimax 1 rear axle air suspended

2/3-axle – less expensive axle load system for best accuracy

Air tubes are routed into the cabin

SG sensor for front axle and 2 air sensors for rear axle offer you the best accuracy. The influence of inclination or slightly uphill/downhill standing is partly compensated in this configuration, as well as load indicating is unaffected of the distribution of goods loaded on the vehicle.

3-axle – easiest to install axle load meter for best accuracy

No air tubes inside the cabin

SG sensor for the front axle and 2 air sensors for the rear axles are connected to Kimax sensor box on chassis. Sensor box communicate weight data with Kimax display inside the cabin.

Air circuits and sensors

On all vehicles you get optimal accuracy with two independent air inlets for
each axle, one for each pneumatic circuits (right and left) per axle or axle
group on air suspended axles, Kimax 2 calculates the current axle load on
each axle from two reference values LO and HI.


• When less accuracy is enough for you, one air inlet on each axle or axle
group is available too.

•Using a single SG sensor on a front axle typically offer you the same
accuracy compared with an front axle with air suspension

Optional versions:

Kimax 2 is exactly as flexible as your vehicle:

Do you have a tractor equipped with air suspension on both front axles
and rear axles combined with a lift axle? No problem!

Do you have a truck with 2 front axles equipped with steel springs and
two rear axles divided in left hand and right hand air circuits? No

Do you want to couple a trailer or semitrailer on the above vehicles?
No problem!

Do you want to couple a low bed trailer equipped with hydraulic
suspension on a tractor equipped with air suspension? No problem!

Do you want to swap from one trailer to another trailer? No problem!
– Individual calibration values are stored in the Kimax unit on each

Assosiated units

Kimax 2 Radio are able to communicate with both Kimax 2 Universal and
Kimax 2 Sensor as input devices

Kimax 2 output units is RS-232 thermal printer or 433 MHz
Wireless terminal.
