摘要： A mass comparator including a weighing chamber (16); a draft shield (18, 20, 22), which surrounds the weighing chamber; a climate module (34), which is detachably disposed in the weighing chamber; a processor (32), a data input unit, and a data transmission path, over which data is exchanged between the climate module and the processor. The processor is programmed to use the air pressure, the air humidity and the air temperature in the weighing chamber to determine, based on the density of a substance to be weighed, an air buoyancy of at least one test sample and/or a buoyancy correction factor. Also disclosed are a climate module configured to electrically yet detachably couple to a mass comparator, and a method for operating a mass comparator including determining the air buoyancy and/or the buoyancy correction factor.

摘要： A balance has a draft shield provided therefor. The shield has a base with upper and lower base covers (5, 6). The upper cover has a central hole in the middle thereof. A windproof ring is placed above the upper cover around a weighing pan of the balance. A shield (7) that is placed between the upper cover and the lower cover receives a weighing sensor (8) of the balance. A wind shield is placed above the base and a weighing compartment for receiving the weighing pan is placed between the wind shield and the upper cover. The windproof structure also has an isolation baffle (2) that is placed between the weighing pan and the upper cover. The high-accuracy balance of the present invention may effectively prevent air flow disturbances inside the balance.

摘要： An improved weight estimation apparatus includes a closed elastomeric bladder filled with fluid and installed in the foam cushion of a vehicle seat bottom, with at least one pressure sensor installed in a closed exit port of the bladder. A temperature sensor disposed in proximity to the bladder provides a temperature signal, and a controller estimates the weight of the occupant based on the temperature and pressure signals. The pressure sensor is preferably configured to sense the gage pressure--that is, the differential pressure between the fluid and atmospheric pressure--at the center of gravity of the fluid in order to provide a stable output independent of changing atmospheric pressure and changing orientation of the bladder due to vehicle pitch and roll.

摘要： An on-board load weighing system for determining the magnitude of the load carried by a tractor trailer truck is provided. The weighing system includes one or more load sensors that are placed between the load platform on which the load is applied and the suspension system of the truck/trailer. The load sensors are connected to one or more transmitters. Each transmitter includes an on-board microprocessor that has its own memory. The microprocessors use calibration data stored within the memory combined with data provided by the load sensors to determine the magnitude of the load being applied to the load sensors. The transmitters then provide an indication of the load being applied to the load sensors to a master controller located in the cab of the truck. Each transmitter is connected to the master controller in a network. Upon power-up, the on-board controller interrogates each of the transmitters in the network in order to determine how many transmitters are present. During operation, the on-board controller receives load data from each transmitter and displays the resulting load data on a display in the truck. Each transmitter can also include an attitude sensor and temperature sensor. The attitude sensor provides the transmitter with data regarding the attitude of the vehicle in which the transmitter is mounted while the temperature sensor provides the transmitter with temperature data. The transmitter uses the attitude data and temperature data along with calibration coefficients in order to increase the accuracy of the system.

摘要： An integrating system for measuring the total weight of material moved by an endless belt conveyor over a weighing scale. The system compensates for the effect of temperature upon the dimensions of the structures that transmit belt loading forces to the load cell. A temperature responsive transducer at the conveyor provides an input to a temperature compensating multiplier which introduces a temperature compensating factor into the weight computation.
