Weighing apparatus

A windshield structure () is provided for a weighing balance () having a base body (), a floor (), and a load receiving arrangement (). The base body and the floor, which is attached to the base body, are positioned horizontal to the ground surface. The load receiving arrangement has a load receiver, with the windshield structure arranged below the load receiver. The windshield structure has a central portion and a circumferential portion that surrounds the central portion. The central portion also has a topological surface with a plurality of alternating hills () and valleys () which aid in regulating airflow below the load receiver.

A laboratory balance () has a housing, a base body () with an upper side () facing a weighing pan () and an underside () facing in the opposite direction of the upper side (). A draft shield () is mounted on the upper side of the base body. The draft shield has a top wall (), a first sidewall (), a second sidewall () that is to the first sidewall, and a front wall (). The first sidewall is operated by a first motor unit () which is located in the base body. The underside has a first opening () that provides access to the first motor unit.

Laboratory balance with a motorized draft shield

A laboratory balance () has a base body (), a weighing chamber () with a weighing chamber floor (), a weighing chamber rear wall (), and a draft shield (&#x2033;). The draft shield has a top wall (), a first side wall (), a second side wall () arranged parallel to the first side wall, and a front wall (). The weighing chamber floor, the draft shield and the weighing chamber rear wall act together to enclose the weighing chamber. The weighing chamber rear wall has a modular construction, with at least a base module () and a top module (&#x2033;). The base module is connected to the base body, and the top module is connected to the top wall of the draft shield.

A draft shield (&#x2033;) is provided for a laboratory balance () with a base body (), a weighing chamber () with a weighing chamber floor () and a weighing chamber rear wall (). The draft shield has a top wall (), first and second side walls () and a front wall (). The draft shield, the weighing chamber floor and the weighing chamber rear wall enclose the weighing chamber. A drive unit () connected to the top wall serves to open and close the top wall (). The weighing chamber rear wall has a base module () and a top module (&#x2033;), at least a portion of which is configured as a compartment. The drive unit is arranged in the compartment-shaped portion.

A laboratory balance () has a weighing pan () in a weighing chamber (). A rear wall () separates the weighing chamber separates from a housing () that contains a weighing cell () with a load-receiving structure (). A suspension pin () extends in a transverse direction of the load-receiving structure. The weighing pan is engaged with the load-receiving structure through at least one passage opening () in the rear wall. Two spaced-apart sidebars () of the weighing pan are held together by a connecting member (). Each sidebar has an L-shaped configuration with a horizontal foot portion () and a vertical leg portion (). A hook-shaped portion () of the vertical leg is seated on the suspension pin, through sliding contact between the suspension pin and a guiding portion () that extends from the hook-shaped portion away from the horizontal foot portion, sloping upwardly.

An instrument () for gravimetrically determining moisture content has a housing (), with a weighing device () arranged inside. The weighing device () has a load receiver () onto which a sample () is placed. The housing has a stationary housing part () and a movable housing part (), the movable housing part alternately occupying a measuring position and a loading position. In the loading position, the respective housing parts are spaced apart from each other, allowing a sample to be put on the load receiver. In the measuring position, the respective housing parts form an essentially enclosed testing compartment () that surrounds the load receiver. A means (), arranged in the testing compartment, heats a sample that is placed on the load receiver. The movable housing part is moved between the respective positions by a position-changing device.

An instrument () for gravimetric moisture determination has a housing () and a weighing device () arranged inside. The weighing device has a load receiver () onto which a sample () is placed. The housing has stationary () and movable () housing parts, the movable housing part alternately occupying a measuring and a loading position. wherein in the loading position the stationary housing part and the movable housing part are spaced apart from each other in such a way that a the sample can be put on the load receiver, wherein in the measuring position the respective housing parts form an essentially enclosed testing compartment () surrounding the load receiver (), and wherein a sample-heating means () is arranged in the testing compartment to heat the sample on the load receiver. The instrument also has an electrical contact means () with first () and second parts (). The first part is connected to the movable housing part and the second part is connected to the stationary housing part. In the measuring position an electrical connection exists by way of the respective parts of the electrical contact means and wherein in the loading position the same electrical connection is interrupted.

An instrument () for gravimetrically determining moisture content has a housing (), with a weighing device () arranged inside. The weighing device () has a load receiver () onto which a sample () is placed. The housing has a lower, stationary housing part () and an upper, movable housing part (), the movable housing part alternately occupying a measuring position and a loading position. In the loading position, the respective housing parts are spaced apart from each other, allowing a sample to be put on the load receiver. In the measuring position, the respective housing parts form an essentially enclosed testing compartment () that surrounds the load receiver. A temperature sensor () is arranged so that the temperature sensor is above the load receiver in the measuring position and is essentially to the side of the load receiver in the loading position.

A balance () with a housing () containing the weighing mechanism and associated electronic components has at least three positioning feet (') to stand on a supporting surface (), at least two of the positioning feet () being height-adjustable for setting the balance () into a level position. In addition, the balance () has at least one stabilizer foot () which can be locked and unlocked, so that for adjusting the level position of the balance, the stabilizer foot is released and thereby enabled to stay in contact with the supporting surface (), and after the level adjustment of the balance has been completed, the stabilizer foot is locked in place to secure the stability of the balance () in its set position.

Balance with stabilizer foot device

A balance () has a weighing compartment () that borders on a stationary part () of the balance and is otherwise enclosed by at least one side wall panel (), a front wall panel (), and a top cover panel (). At least one of the panels is slidable by means of a guiding device () to open and close the weighing compartment (). The balance () further has cutout passages () in the side wall panels (), the front wall panel (), the top cover panel (), and/or the rear wall of the weighing compartment, so that cables and/or conduits can be introduced from the outside into the weighing compartment.
