ELEVATOR CAR LOAD MEASUREMENT SYSTEM AND METHOD FOR DETERMINING A LOAD OF AN ELEVATOR CAR
20200130989 · 2020-04-30 ·

An elevator car load measurement system for determining a load of an elevator car includes a plurality of at least two force sensors that are daisy-chained and connected to a controller for determining the load. Each force sensor measures a force exerted by the elevator car on the respective force sensor and generates a frequency signal with a square-wave form, wherein the frequency signal is proportional to the respective measured force. At least one of the force sensors adds a first frequency signal received from the previous force sensor along the daisy chain a second frequency signal generated by the at least one force sensor to generate a frequency sum signal, the last of the force sensors in the daisy chain forwards the frequency sum signal to the controller.

Offset weighing apparatus

An offset weighing apparatus and method for use with poultry processing equipment includes a weigh assembly to weigh an animal connected to a shackle assembly as the shackle moves in contact with a force sensor along a conveyor line. A diverter assembly laterally displaces a shackle retaining the animal from below the conveyor line into engagement with the force sensor. The bending axis of the force sensor is approximately parallel to the displaced shackle. The angular position of the bending axis and shackle, and relative positions, friction, and forces of the components of the shackle assembly and weigh assembly are analyzed to calculate the weight of the animal connected to the shackle without removing the animal from the shackle or ceasing movement of the conveyor line.
