The invention discloses a measuring device for measuring the mass of a weight, comprising: a main frame; a main beam supported on main frame; a balancing system loaded on one end of the main beam; a weighting system, loaded on the other end of the main beam; a weight transportation system capable of transporting and loading a standard weight or a test weight into the weighting system and capable of unloading and transporting them away from the weighting system; and a control system comprising an optical sensor mounted in the main frame, a laser displacement sensor mounted on the main beam, a monitor, and a control unit connected electrically to the optical sensor, the laser displacement sensor and the monitor. The control system is adapted to compare a main beam first displacement data obtained by the optical sensor and a main beam second displacement data obtained by the laser displacement sensor to accurately measure the actual displacement of the main beam.

A dispersing tray is mounted to a combination scale at a top part thereof to disperse and deliver supplied articles outwardly. The dispersing tray has, on a back surface thereof, a liquid stopper that prevents outward movement of a liquid.

Provided is an overload prevention mechanism having a structure that protects a weight sensor with a floating action and ensuring the reproducibility of the return position of the weight sensor. The overload prevention mechanism has a resilient member that is interposed between the weight sensor and the case, supports the weight sensor in a pressing manner against the case, and when a certain plate load or greater is imposed causes the weight sensor to separate from the case and thereby be released from the load, a guide member that is arranged in a standing manner between the weight sensor and the case, and a guide receiving seat that is provided in the weight sensor or the case and engages with the guide member.

A system for determining the mass of a vehicle includes a mass estimation module for estimating an approximate initial mass value for the vehicle and a force estimation module configured to determine a force value indicative of the force output from the vehicle powertrain. A mass determination module includes a recursive least squares module configured to perform in real-time a recursive least squares calculation based on the approximate initial mass value, the force value, and an acceleration value for the vehicle so as to provide a determination of vehicle mass. The mass determination module is further configured to receive a signal indicative of a user behavior event which indicates a change in the mass of the vehicle, and the mass determination module is configured to determine, in response to the user behavior event, a new approximate initial mass value for a subsequent recursive least squares calculation.

This disclosure provides a combination scale including a dispersing feeder, linear feeders, a plurality of hoppers, and a collector. The dispersing feeder and linear feeders are respectively disposed in upper parts of a center base of the combination scale to disperse and deliver outwardly articles received therein. The hoppers are removably mountable to an outer periphery of the center base to hold and discharge the articles. The collector collects the articles discharged from the hoppers on a central side of the center base and discharges the collected articles. The collector constitutes a collecting and discharging channel for the articles to be collected and discharged. The combination scale further includes a shielding tool configured to block liquid that drops from the center base downward into the collecting and discharging channel.

A sensor includes a first detector and a second detector. The first detector detects an electromagnetic noise varying according to a distance between the sensor and a human body and changes an output according to the electromagnetic noise detected. The second detector detects a detection load applied to a detection surface of the sensor and changes an output according to the detection load.
