Abstract: Systems and methods for calibrating an onboard vehicle scale may include disposing a vehicle upon a reference scale; determining reference weight information corresponding to a weight of at least a portion of the vehicle using the reference scale; automatically and wirelessly communicating the reference weight information to an onboard scale coupled to the vehicle; and automatically calibrating the onboard scale using the reference weight information.

Abstract: Devices and methods of measuring a loaded weight of a vehicle are disclosed. The device may include a sensor assembly configured to detect pressure in the at least one air spring. The device may additionally include a solenoid valve assembly disposed between the sensor assembly and the at least one air spring and configured, when the sensor assembly is not detecting the pressure, to isolate the sensor assembly from the pressure in the at least one air spring while not isolating the at least one air spring from the pressure source. The device may further include a processor assembly configured to calculate a loaded weight of the vehicle based on the detected pressure, and a display assembly configured to display the calculated loaded weight.

Abstract: A dual gauge system determines pressures of two separately contained gases by use of two separate pointer—Bourdon tube sections within the dual gauge. The Bourdon tube of a first one of the sections is gaseously coupled to a first one of the contained gases to determine pressure of the first one of the contained gases and a Bourdon tube of a second one of the sections is gaseously coupled to a second one of the contained gases to determine pressure of the second one of the contained gases. Accuracy of pressure determination is enhanced by allowing for separate calibration of each of the two gauge sections.
