History of On-Board Electronic Truck Scales and Future Design Trends

Most present on-board scales utilize a micro-processor based meter in a cab and one or more remote “transmitters” out near the load sensors. The transmitters each have a voltage to frequency converter to digitize the transducer data. A new generation of on-board scale electronics is being designed which utilizes a network for the remote transmitters. The new transmitters contain their own micro-computer and calibration data storage. Digital data is sent over the network to a “master controller” in the cab. The master provides a direct interface to an on-board computer.
