A draft protection device (2) has a wind-blocking body (20; 21) that consists of at least two panel elements (20A,20B, 20C; 21A, 21B) and partially encloses the weighing compartment of a balance (1) in which a weighing pan (15) is arranged. The wind-blocking body (20; 21) can be selectively positioned by hand in at least two different orientations. In each of the different orientations at least one opening is available for access to the weighing compartment. The wind-blocking body (20; 21) can be positioned by the user in such a way that the openings resulting from the differently oriented positions allow access to the weighing compartment from different directions.

A draft shield for a balance that has a balance housing has a rear wall and a front wall panel arranged in a fixed position to the rear wall, at least two side wall panels and a top cover. The rear wall and the front wall panel are connected to a base. The base has a locking device and the balance housing has a complementary locking element. The locking device and the locking element cooperate with one another to releasably attach the draft shield to the balance housing, wherein the locking device and the locking element are configured to release the draft shield without moving the draft shield.

A top-loading precision balance with a draft protection device which includes several walls connected to each other at the edges thereof, and a cover which closes the opening defined at the top of the walls. The cover is fastened through a horizontally extending hinge to one of the walls. The hinge of the cover includes a spring which acts against the direction of movement for closing the cover. The spring mounted in the hinge is a torsion spring which is fixed at both ends thereof. The frame forming the bottom of the draft protection device has on its bottom side a groove into which lugs mounted on the balance housing engage when the draft protection device is placed on the balance housing. A spring is fastened at the groove of the frame under the front side of the draft protection device. The spring engages in a groove of one of the lugs.

The method and the device serve to monitor the alignment of a measuring instrument, specifically a balance. To perform this function, the monitoring device is equipped with an inclination sensor based on the principle of a spirit level, with a container filled with a fluid in which a bubble is formed. According to the invention, the position of the bubble is measured optically by means of a radiating element that is arranged on one side of the bubble and serves to emit a radiation, and a sensor element that is arranged on the opposite side of the bubble and serves to receive the radiation. The radiating element, preferably a light-emitting diode, and the sensor element, preferably a photodiode, together define the sensor axis (sx) on which the bubble is centered as long as the sensor axis runs parallel to the axis of the gravity force. Furthermore, the sensor element is flanked by at least two reference elements that are likewise receiving the radiation. The reference elements serve to test whether the intensity of the radiation is within a permissible range. A function test is performed automatically inside the monitoring device in order to verify that the monitoring device is functioning correctly.
摘要:
A balance with a balance housing serving to accommodate a weighing mechanism and weighing-related electronics is equipped with a weighing pan and with a draft protection element which can be loosely positioned on the balance housing and which surrounds the weighing pan. The balance housing is equipped with a step which serves to receive the draft protection element and whose seating surface for the draft protection element is arranged below the topside of the balance housing.
摘要:
A device for monitoring an operating condition is incorporated in a balance with a weighing cell, an electronic weighing circuit arrangement (15), an output unit (21, 22, 44), and at least one electronic inclination sensor (13). The circuit arrangement (15) includes a signal-processing device (17), a memory device (19) as well as a time clock (20). Based on a sensor signal received from the electronic inclination sensor (13), the signal-processing device (17) determines a quantity that is indicative of the operating condition of the balance. The signal-processing device (17) also determines the current time and assigns a time value to the quantity that represents the operating condition. The resultant vector-like sets of time and operating condition data are transmitted to and stored in the memory device (19), so that the data are at all times available for transmission to an output unit (21, 22, 44).
摘要:
An arrangement for aligning an apparatus unit with respect to the direction of gravity. The arrangement includes a first support device, a second support device and a third support device acting on a first support point, a second support point, and a third support point, respectively, of the apparatus unit. A measuring level serves to control the alignment of the apparatus unit. The first and second support devices are vertically adjustable. The three support points are arranged in the corners of a triangle. Two separate optically distinguishable partial areas are marked in the region of the measuring level, wherein the first partial area is intersected by a plane through the center of the measuring level extending perpendicularly to the line connecting the first support point and the third support point, and wherein the second partial area is intersected by a plane through the center of the measuring level extending perpendicularly to the line connecting the second support point and the third support point.
摘要:
A balance (1) with a housing (3) containing the weighing mechanism and associated electronic components has at least three positioning feet (5, 5′) to stand on a supporting surface (20), at least two of the positioning feet (5) being height-adjustable for setting the balance (1) into a level position. In addition, the balance (1) has at least one stabilizer foot (6, 106) 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 (20), 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 (1) in its set position.
摘要:
A balance has a balance housing (21), an operator console (4), and a pivot arrangement (17, 18, 22) between the balance housing and the operator console. The pivot arrangement works as a hinge, so that the operator console can be tilted about a transverse horizontal axis (A) that runs parallel to the balance housing. From a normal working position, i.e., projecting forward from the balance housing, the operator console can be folded upward into a rest position. The pivot arrangement has a certain amount of loose play in at least one radial direction. The operator console has a tilt-adjustable part (20) and a tilt-angle adjusting device (26, 27, 28, 29) with a secondary transverse tilt axis (B) located in an anterior portion of the operator console. A locking device (30b, 33) serves to secure the tilt-adjustable part in one of at least two selectable tilt-angle positions.
