Axle Load Meter

Cabin version for drivers cab: The Kimax 1 axle load display is supplied with a mount for simple installation on the dashboard

The scale you take with you …

Kimax 1, the axle load indicator for economical and convenient supervision of axle loads on trucks equipped with a mechanical spring suspension system for the rear axle(s).

Kimax 1 onboard scale calculates the current axle load from the current strain in axle(s) / springs.

Axle load is displayed as a three-digit-value.

SG sensors installed on the rear axle or the springs are connected to the display through a connector.

… and warns when limits are exceeded

Kimax 1 has two separately adjustable alarm levels. Exceeding alarm level 1 is indicated by a flashing display. Exceeding alarm level 2 switches in an internal relay.

The relay signal can be used as ON/OFF input for another unit, for example an on-board computer a GPS tracking system or an external lamp.

Kimax 1 load scale for trucks assist you in achieving economical transportation, avoid fines and simultaneously optimize the cargo weight.

Sensor configuration

For 2-axle vehicles you can install the SG sensors directly on the rear axle.

For 3-axle vehicles we recommend SG sensors installed on the parabolic springs.

Axle load measurement

Kimax 1 uses the linearity between strain in the axles and load of the single axles

By using two reference points (empty weight and weight at maximum load) and the current measured strain, Kimax 1 calculate the current axle load with an accuracy of 2% of the maximum load.

Basic operation

The strain in the axles will increase linear with the load above the axles.

The Sg sensors are installed  either on the axle or on the parabolic springs depending on the mechanical size of the differential gear box.



2 SG sensors on the single rear axle

P/N 013000-0100 + additional 1 x P/N 10251  Double SG sensor CL3

In this version, the reading is measured only on the rear axle.


2 SG sensors on the springs for the rear axles

P/N 014000-0100 + 2 x P/N 10208 SG sensor CL3

In this version the reading is measured on the rear axle springs.

Display of reading

KIMAX has a three-digit 7-segment LED display. The decimal points can be set at the second or third digit or removed completely depending on weighing range.

Two modes of display can be selected for onboard truck scale:

• Automatic switch off of display after approx. 2 minutes reading (recommended in cabins).

• Continuous display readings (factory setting).


RS-232 serial output (option 1) Kimax 1 is available with a serial output in RS-232 format, offering you the displayed value in digital format intended for on-board computers or GPS/tracking units.

Analogue output (option 2) Kimax 1 is available with an analog 0-5 V output corresponding to the displayed value you read on the unit. This output is intended for on-board computers or remote display purpose.

Serial printer output (option 4) Kimax 1 is available with output for most common serial printers.

Trailer version – for trailers/semitrailers intended for use on trailers and semitrailers: the display is designed for mounting in a sturdy, waterproof stainless steel housing direct on the chassis.
