A force transmission element for a balance or load cell is adapted to be arranged between a load receiving unit, receiving the load to be weighed, and a load application point of a load cell, in order to transmit the load force exerted by the load. The force transmission element is designed at least partly as a framework composed of hollow rods, in particular round rods, wherein the force transmission element, in particular the hollow rods, is/are produced at least partly using 3D printing technology.

Methods and systems for eccentric load error correction are disclosed. A plurality of weighing data sets for a weight having a mass value are obtained, where the weight is loaded at different positions on a weighing platform of a weighing device. Differences between each of the weighing data sets and the average value of the plurality of weighing data sets or the mass value of the weight are calculated. Sensor correction coefficients are calculated and updated when the maximum absolute value of the differences exceeds a pre-set threshold. The weighing data sets are updated. The above steps are repeated until the absolute values of all the differences are less than the pre-set threshold.

A fluid container measurement system is disclosed. The fluid container measurement system is configured to suspend a load measurement assembly a distance above a support surface. The load measurement assembly houses a load cell and a measurement control circuit. The measurement control circuit is coupled to the load cell and configured to receive electrical signals indicative of a force imposed on the load cell. Electrical signals generated by the load cell indicative of the force exerted on the load cell can be used to measure the fluid container attached to the load cell linkage member.

An integrated high-precision weighing module has a shell, an electromagnetic force sensor, a printed circuit board (PCB), a weighing pan component, a support ring, and an air baffle ring. The electromagnetic force sensor and the PCB are mounted in the shell. A bearing head of the electromagnetic force sensor extends upward from an upper end portion of the shell. The support ring sheathes the bearing head. The weighing pan component is mounted on the bearing head, with the support ring located between the weighing pan component and the shell. The air baffle ring is disposed around the weighing pan component and located on the support ring. A first airflow channel is formed among the shell, the support ring, and the air baffle ring. At least part of airflow in the shell flows to the outside through the first airflow channel.

A method for estimating the weight of loads carried by implements may include controlling an implement subject to actual weighing conditions to lift a load and receiving an input indicative of a sensed force associated with lifting the load. The method may further include determining a correlation value indicative of a correlation between first and second force values for lifting a given load with the implement as a function of the actual weighing conditions and as a function of nominal weighing conditions, respectively, where at least one of the actual weighing conditions differs from at least one of the nominal weighing conditions. Furthermore, the method may include determining an adjusted force value for lifting the load based at least in part on the sensed force and the correlation value. Additionally, the method may include estimating the weight of the load based at least in part on the adjusted force value.
