Abstract
An apparatus and methods are provided for for indicating load weight of a vehicle. The apparatus preferably includes a fluid pressure sensor, such as a transducer, associated with a fluid pressure line of a vehicle for producing a plurality of fluid pressure signals representative of a corresponding plurality of load weights and a load weight indicating device responsive to the sensor for indicating a plurality of load weight levels. The load weight indicating device includes a memory for storing a calibration signal representative of a predetermined load weight limit level and a comparator in communication with the memory and the sensor for comparing the calibration signal to the plurality of fluid pressure signals. The device also preferably includes a plurality of indicators responsive to the comparator for indicating at least two load weight levels. The plurality of indicators include a first load weight level indicator for only indicating when the load weight level exceeds the predetermined load weight limit level and a second load weight level indicator for only indicating when the load weight level is below the load weight limit level.
