SWEDEN'S Axel Johnson group has developed a new type of vehicle-mounted weighing system, the Aton Load Indicator.
Using `S'-shaped steel strain sensors welded on either axles or bogies, it gives a continuous register of the tension to which the load-carrying parts of the chassis are subjected. The sensor unit is steel encased and hermetically sealed to prevent damage and is not affected by over-loading.
Signals from the sensor are relayed to a read-out instrument incorporating a micro computer which is plugged into a cassette unit mounted in the cab. The instrument has buttons for gross weight and net weight as well as axle/ bogie pressure.
A three-digit read-out panel gives the result and overload is indicated by a warning lamp, although an outer alarm device can be coupled to the unit.
Accuracy of the system is said to be good, at plus or minus 1 per cent of the effective range down to a minimum of plus or minus 50kg (1101b). It is said that as the read-out instrument fits all Aton cassettes it can be replaced or moved from one vehicle to another without re-calibration.
The load indicator was developed in conjunction with Scania and will be manufactured by Amlab AB, Nynashamn, Sweden.
