The present invention relates to a sensing and control device (40) and method for a weight measurement device (30) comprising a load unit for loading material to be weighted. To enable precise measurement with less expensive components, said sensing and control device comprises analog circuitry (50) configured to receive a weight measurement signal, convert the received weight measurement signal into a first voltage signal, subtract a second voltage signal representing the weight of at least the load unit without being loaded with material to be weighted from the first voltage signal when the load unit is loaded with material to be weighted to generate a third voltage signal representing the weight of the material to be weighted, and control circuitry (60) configured to receive the first voltage signal while the load unit is not loaded with material to be weighted, convert the first voltage signal into a first digital signal, and generate a pulse width modulated, PWM, signal having a pulse width representing the weight measured by the load unit while not being loaded with material to be weighted, and further configured to convert the third voltage signal into a second digital signal representing the weight measurement of the material to be weighted. The analog circuitry (50) is configured to generate the second voltage signal from the PWM signal generated by the control circuitry, wherein the voltage level of the second voltage signal is proportional to the pulse width of the PWM signal.

A load measurement system for a mixer comprising a mixing drum configured to contain and mix concrete, a cradle adjacent to the mixing drum and configured to receive the mixing drum, and a load measurement device adjacent to the cradle and configured to determine the changes to a material property of the cradle due to the force exerted on the cradle by the load in the mixing drum. The load measurement system determines the amount of the load of concrete in the mixing drum based on the measured change to the material property of the cradle, which may include one or more of a material deformation, displacement, stress, strain, or the vibration of the cradle.

WEIGHT SCALES SYSTEMS AND METHODS
20220326066 · 2022-10-13 · ·

A weight scale system is for measuring the weight of an object, which includes a bed section, a vertical separator actuator and a controller. The bed section includes a lower-platform, an upper-platform and weight sensor assemblies located on the lower-platform, each includes at least one weight sensor. The bed section further includes at least one vertical-separator. The vertical-separator actuator is coupled with the vertical-separator and with the controller. The controller is coupled with the weight sensors. The controller directs the vertical-separator actuator to operate the bed section in at least two modes, a referencing mode in which the vertical-separator detaches the upper-platform from the weight sensor assemblies, thereby enabling referencing the weight sensors, and a weighing mode, in which the vertical separator re-attaches the upper-platform with the weight sensor assemblies, such that the weight associated with the upper-platform is fully applied on the weight sensors.
