A load carrier with a receiving pan for a free-flowing substance, a calibration weight holder for supporting a calibration weight, and a connector element for connecting the load carrier to a load receiver of a weighing cell. The receiving pan is arranged between the connector element and the calibration weight holder and is designed to be loaded with the free-flowing substance through a passage in the calibration weight holder. The calibration weight holder can be loaded with a calibration weight independently of the load status of the receiving pan.

Load carrier

A calibration weight arrangement () for an electronic balance with a force-transmitting mechanism () has a calibration weight () adapted to be coupled to the force-transmitting mechanism. The arrangement also has a transfer mechanism and a drive source to manipulate the calibration weight in a guided movement. The drive source includes an actuator () cooperating with the transfer mechanism and at least one piezoelectric element () which drives the movement of the actuator. The piezoelectric element interacts with a drive wheel () that is centrally positioned relative to the calibration weight arrangement and drives a likewise centrally positioned shaft (). The interaction between the piezoelectric element and the drive wheel occurs during the advance movement in one direction through the repeated engagement and release of a frictional contact force.

Calibration weight arrangement for an electronic balance

Weighing device with at least one weighing cell and with a receiving structure serving to hold the at least one weighing cell, wherein the at least one weighing cell includes a first fastener device serving to fasten the weighing cell in the receiving structure, and the receiving structure includes a second fastener device which is a complementary counterpart of said first fastener device. The fastener devices include a detent engagement mechanism and are designed in such a way that they hold as well as release the weighing cell by means of a form-locking engagement which can be locked and released, respectively, by a simple action in the form of pushing in the direction of the load and pulling against the direction of the load.

Weighing device

Load cell for a scale

A force-measuring cell is designed for a receiving structure having multiple force-measuring cells of the same type. Each cell in the receiving structure occupies a design space whose dimensions, projected into a plane orthogonal to the load direction, is delimited by the design spaces of neighboring and/or is equal to the largest dimension of the cell in the plane. The cell has parallel-guiding diaphragms arranged on upper and lower surfaces thereof. The cell includes a calibration weight arrangement with a calibration weight which can be coupled to the cell, as well as a drive mechanism and a transfer mechanism for guidedly moving the calibration weight. An actuator works together with the transfer mechanism and a piezoelectric element that drives the actuator. The actuator has at least two interacting elements to repeatedly engage and release each other by frictional contact force which occurs during the travel movement in one direction.

A weighing modulehas a force-transmitting linkagearranged between the load-receiving portionof the weighing celland the load receiver, with an overload protection device that precisely maintains its position being an integral part of the force-transmitting linkage. By means of a positioning element, the load receiveris positioned without play relative to the load-receiving portionin the plane that extends orthogonal to the load direction, and the load receiveris also guided in the load direction without play. When forces in excess of the pre-tension force of the elastic elementact on the load receiver, the latter has the capability of being displaced in the load direction and to tip in all directions that are orthogonal to the load direction. The housing partserves to delimit at least the range of linear downward deflection as well the tipping movement of the load receiverwhen the load receiveris exposed to transverse forces and to overloads. The rotation constraintis rigidly connected to the load receiverand engages a housing-connected recess. To position the load receiverrelative to its operating environment, a positioning deviceis provided, whose central longitudinal axis coincides with the central longitudinal axis of the load receiver

Weighing module with precisely-positionable overload protection device

A device to weigh substantially uniform weighing objects has a plurality of weighing modules and an equal number of load carriers that have central lengthwise axes extending in the direction of the load. Each of the load carriers is connected, respectively, to one of the weighing modules through a force-transmitting rod, and the load carriers are disposed in a given spatial or two-dimensional arrangement in which the distances between neighboring central lengthwise axes are smaller than the largest lengthwise extension of the respective weighing modules.

Device for weighing substantially uniform weighing objects

A weighing cell module with a force-transfer mechanism that includes a parallel-guiding linkage with a vertically movable parallelogram leg and a spatially fixed parallelogram leg, is equipped with a mounting area for a first weighing-pan support device with a single-point connection of a weighing pan, as well as with a mounting area for a second weighing-pan support device with a multiple-point connection, particularly a four-point connection, of a weighing pan, wherein the first and the second mounting area are each connected to the force-transfer mechanism. As a result, the weighing cell module can be used to manufacture different types of balances in a design family of balances, where each different type within the family is designed for a different maximum load.

Scale pan mount for single-point or multi-point mounted scale pan

The invention relates to a device for measuring properties of a longitudinally moved test material in a measuring cell. In order to provide a device which is easier to adapt to the requirements of a customer and to the special conditions of a production machine for longitudinally moved test material, the measuring cell ( ) is connected to a processor ( ), which is associated exclusively with the measuring cell.

Device for measuring properties of a longitudinally moved specimen such as yarn

The invention relates to a device for monitoring a yarn (1), which is moving in its longitudinal direction, using a measuring head and an evaluation unit (7) which is spatially separate from and connected to the measuring head. To enable optimum use of measuring heads operating according to different physical principles without unduly increasing the outlay, the measuring head includes a first part (2) operating according to a first measuring principle and having a connection (5) to a first part (6) of the evaluation unit for making an evaluation according to the first measuring principle. The measuring head then comprises a further part (9) operating according to a further measuring principle and having a releasable connection (8, 10) to the first part. In addition, the evaluation unit likewise comprises a further part connected by a releasable connection for the evaluation according to the further measuring principle.

Device for monitoring a moving yarn

The invention relates to a yarn sensor for scanning a yarn (2), which is moving in its longitudinal direction in a measuring gap (3), with a light beam from a light source (4), having a first receiver (7) for directly transmitted light, at least one second receiver (5, 6) for light reflected by the yarn and one element each (8, 9, 10, 11) for transmitting the light between the measuring gap, the light source and a receiver. To keep the overall size and the external dimensions as small as possible, the optical axes (12-15) of the elements for transmitting the light are disposed together in one plane lying at least approximately at right angles to the yarn.
