Axle Load Meter – for trailers/semitrailers

Kimax 2 sensor is a slave unit without display intended for communication with Kimax 2 radio or Kimax 2 universal through device bus.
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 with air suspension system.
Due to the modular construction, the product is very flexible and can be individually adapted to most vehicle conditions.
One tractor can easily shift from one trailer to the next without re-calibration, calibration parameters are stored in the Kimax 2 sensor itself.

Sensor configuration

On all vehicles you get best accuracy with two independent air inlets for each axle, one for each pneumatic circuit (right and left) per axle or axle group, Kimax 2 calculates the current axle load on each axle from two reference values LO and HI pr axle.
A dual or triple axle group can be measured by one measuring channel, a 2-axle trailer needs a Kimax 2 sensor equipped with two measuring channels.

Kimax 2 sensor has two separately adjustable alarm levels

Alarm 1 is indicated by a flashing diode for the individual axle on the connected Kimax 2 radio or Kimax 2 universal display unit.
Alarm 2 which switches in an internal “relay” when the total weight for this vehicle is exceeded. The relay signal can be used as ON/OFF input for a warning lamp or another unit, for example a tracking GPS or an on-board computer.

Air circuits

On vehicles with two independent pneumatic suspension circuits per axle or axle group, the air pressure is measured for each pneumatic circuit with the 2-sensor version and Kimax 2 calculates the current load from these two values.

You obtain improved accuracy by using individual air sensors for each air bellow.

Axle load measurement

Kimax 1 uses the linear interrelationship of the air pressure in the suspension system and the axle load: By using two reference points(empty weight and weight at maximum load) and the current measured air pressure, Kimax 2 calculate the current axle load of the entire triple group with an accuracy of 2% of the maximum load.

Basic operation

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. Trucks are manufactured with one or two level valve(s) pro axle or axle group. In case of one level valve you get good results by using a Kimax with single air inlet, in case of two level valves, you get most accurate weighing by using a Kimax with a double air inlet.

 

Trailer axle suspension for Kimax

1 air inlet most economical version P/N 051000-0151

In this version, the axle load is measured only on one of the two/three axles or axle group. Air pressure in air bellows equals over time and build up an average pressure representing the common axle load.

 

2 air inlets measuring accuracy in all positions P/N 052000-0151

In this version, the reading is calculated for both sides of the axle. This provides additional measuring accuracy (arithmetic mean), particularly when the vehicle is inclined to one side. The axle load reading at dual input show a real value faster compared to single air circuit systems.

Air circuits and sensors

On all vehicles you get best accuracy with two independent air inlets for each axle, one for each pneumatic circuit (right and left) per axle or axle group, 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.

Optional versions:

Kimax 2 is exactly as flexible as your vehicle:
• Do you have a tractor equipped with steel springs on front axle and air suspension on 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 problem!
• Do you want to couple a trailer or semitrailer on the above vehicles, we do it!
• 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, you just do it!

Individual calibration values are stored in the Kimax unit on each vehicle.
