Claim:
1. A scale for mounting on a semi-trailer having an air bag in the suspension and an air line connected to the air bag, the scale comprising: a pressure transducer configured for connecting to the air line and for measuring the pressure in the air bag, and configured to send a signal correlated to the sensed pressure; a process module in electric communication with the pressure transducer and configured to receive the signal therefrom wherein the process module is configured to correlate the signal from the pressure transducer to a weight of a load on the trailer independent of whether the semi-trailer is connected to a prime mover; a display module configured to receive a signal from the process module indicating the sensed weight and display the sensed weight of the load on the semi-trailer wherein the display module is of a size shape and brightness to be visible at a distance of approximately 400 feet; and a compartment having a housing sized to contain and configured to protect the pressure transducer, the process module, and the display module, the compartment mountable to the semi-trailer, and having a display window fixed attached to the housing through which the display module is visible.
