Abstract
A balance having at least one adjusting device (2, . . . ) having a drive, wherein the drive of the adjusting device is configured as a fluidic drive (4, . . . ), to which pressure can be applied by a pressure source disposed outside the scales via a pressure connection.
Claims18
A set of scales, configured as a precision balance or an analytical balance, for weighing a load to be weighed comprising:
- at least one component integral to the set of scales,
- a scales unit housing, and
- at least one adjusting device having a respective drive,
- wherein each said drive of each said adjusting device consists of a gearless, non-pivoting actuator configured as a respective fluid drive,
- wherein each said drive is arranged within the scales unit housing and in communication with at least one pressure connection configured to apply pressure to said respective drive from a pressure source arranged outside the scales unit housing, and
- wherein each said adjusting device is configured to impart exclusively translational motion to said at least one component.
A set of scales, configured as a precision balance or an analytical balance, for weighing a load to be weighed comprising:
- a component integral to the set of scales,
- a scales unit housing, and
- an adjusting device having a drive,
- wherein the drive of the adjusting device comprises a gearless actuator configured as a fluid drive,
- wherein the drive is arranged within the scales unit housing and in communication with a pressure connection configured to apply pressure to the drive from a pressure source arranged outside the scales unit housing,
- wherein the adjusting device is configured to impart translational motion to the component, and
- wherein the component is a wall element of a wind shield of the scales unit housing.
A set of scales, configured as a precision balance or an analytical balance, for weighing a load to be weighed, comprising:
- a component integral to the set of scales,
- a scales unit housing, and
- an adjusting device having a drive,
- wherein the drive of the adjusting device comprises a gearless actuator configured as a fluid drive,
- wherein the drive is arranged within the scales unit housing and in communication with a pressure connection configured to apply pressure to the drive from a pressure source arranged outside the scales unit housing,
- wherein the adjusting device is configured to impart translational motion to the component, and
- wherein, in a washing-down position, a load support is pressed by the actuator of the adjusting device with a rearward sealing edge facing toward the scales unit housing against a seal arranged between the load support and the scales unit housing in sealing manner.
A set of scales, configured as a precision balance or an analytical balance, for weighing a load to be weighed comprising:
- a component integral to the set of scales,
- a scales unit housing, and
- an adjusting device having a drive,
- wherein the drive of the adjusting device comprises a gearless actuator configured as a fluid drive,
- wherein the drive is arranged within the scales unit housing and in communication with a pressure connection configured to apply pressure to the drive from a pressure source arranged outside the scales unit housing,
- wherein the adjusting device is configured to impart translational motion to the component,
- wherein the adjusting device is configured as a transport securing device, which locks the set of scales in a pressure-free condition by spring force, and
- wherein, for locking, the actuator of the adjusting device is configured to:
- engage in locking manner in a corresponding aperture of a load transmitting lever of a weighing system and/or
- press the load transmitting lever of the weighing system against a contact surface.
