Embodiment Construction

[0054] figure 1 A block diagram of a weighing device 1 according to the invention is shown. As can be seen in the block diagram, the weighing device 1 comprises a weighing unit 2 , a control unit 42 and an auxiliary unit 4 .

[0055] Such as figure 1 The weighing unit shown in includes a load sensor 40 , a load receiver 6 and a power transfer unit 8 . When an item to be weighed (not shown) is placed on the weighing unit 2, the force exerted by the item is transmitted by the load receiver 6 to the load cell 40, where the force is converted into a corresponding electrical signal to give the weight of the item. The power transmission unit 8 is used to transmit power to the auxiliary unit 4 . Weighing unit 2 such as figure 1 Power is provided by a standard power supply 14 as shown. The control unit 42 is connected to the weighing unit 2 . The control unit 42 comprises a data transfer unit 26 which is used to transfer data to the auxiliary unit 4 . Such as figure 1 The con...

Abstract

The invention provides a weighing device comprising a weighing unit, a control unit and at least one application unit. The application unit is comprised within a secondary unit which in turn comprises a receiving unit. The control unit comprises a data transmitting unit. The weighing unit comprises load receivers and a power transmitting unit. The secondary unit is placed on the load receivers of the weighing unit leaving a gap between the top side of the weighing unit and the bottom side of the secondary unit. The weighing unit transmits a power signal from the power transmitting unit to the receiving unit of the secondary unit through the gap and a control signal is transmitted from the data transmitting unit to the receiving unit of the secondary unit through the gap. The secondary unit and in turn the application unit is thus powered and controlled contactless by the weighing unit and the control unit respectively.

Description

technical field [0001] The invention relates to a weighing device for a laboratory. Background technique [0002] Weighing devices are commonly used in laboratories to determine the weight or change in weight of a sample. Furthermore, in a laboratory, multiple operations often have to be performed on the same sample. For example, the sample may have to be weighed and additionally stirred or dispensed magnetically or any such manipulation. Instead of using multiple devices to perform these different operations on the same sample, a single device can be used. [0003] Depending on the weighing device being laboratory equipment operated by laboratory specialists, and depending on specific issues in a given laboratory, it may be desirable that different application units be placed where it is most advantageous for the user. On the one hand, however, this conflicts with the fact of operating a weighing device, since the flow of data and power must be maintained between the app...
