摘要： A gravimetric measuring device includes a weighing chamber with a vertical weighing chamber wall, which is formed as a support structure (14) with cover modules (28) detachably fixed thereto on the weighing chamber side, each cover module (28) having, on its weighing chamber side, a module front wall (30) covering the support structure (14) at least partially. The cover modules (28) have locking cantilevers (38) directed towards the support structure such that the locking cantilevers (38) are provided with vertically directed through-openings (40) which are aligned with corresponding through-openings (20, 22) of the support structure (14). The cover modules (28) are locked to the support structure (14) with locking rods (42) which pass through the mutually aligned through-openings (40; 20, 22) of the cover modules (28) and the support structure (14).

摘要： A connecting structure connects a filter housing to a filter housing retaining structure. The connecting structure conducts a liquid that is to be cleaned to the filter housing and discharges a purified liquid. The connecting structure includes a filter housing cover that connects to the filter housing and that receives a filter medium. The filter housing cover has attachment elements that connect to corresponding attachment elements of the filter housing retaining structure to establish an exchange of fluids between the filter housing retaining structure and the filter housing. Filter housing cover guides are on opposing sides of the filter housing cover; and guides on the filter housing retaining structure engage the filter housing cover guides when connecting the attachment elements of the filter housing cover with the attachment elements of the filter housing retaining structure to support and linearly guide the filter housing cover during the connection process.

A second shift weight carrier (34-2R, 34-2L) for vertically mounting, with play, a second shift weight arrangement (22-2R, 22-2L) which likewise has two spaced-apart, parallel carrier arms (30-2R, 30-2L) connected by another bridging piece (32-2), is likewise arranged in a vertically movable manner in relation to the base. The carrier arm pair (30-1R, 30-10 of the first shift weight carrier (34-1) is arranged between and parallel to the carrier arm pair (30-2R, 30-2L) of the second shift weight carrier (34-2), and each shift weight carrier (34-1; 34-2) is articulated to a common crosspiece (12) by two parallel links (23-1R, 23-1L; 23-2R, 23-2L).

摘要： In an integrating A/D converter, first and second reference voltage inputs (18, 20) alternatingly connect through a reference voltage switch (16, 16′) via a first reference resistor (Rref) to an inverting input (122) of an integrator (12). A comparator (22) connected downstream of the integrator (12) compares a test voltage applied to its test voltage input (221) with a comparator reference voltage applied to its reference voltage input (222). This input (221) is connected to- the output (126) of the integrator (12). A control device (40) actuates the first reference voltage switch (16, 16′) in a pulsed manner and measures the time intervals between the individual switching processes. An inverter (24) inverting a measuring voltage (UM) and a first heating resistor (RMH) coupled thermally with a measuring resistor (RM), are connected in series between the measuring voltage input (14) and the output of the first reference voltage switch (16, 16′).

摘要： A gravimetric measuring system (10) includes a balance (12) with a weighing chamber (22), surrounded by a plurality of weighing chamber walls (23, 24, 26, 28); an electromechanical weighing system (181); and an electronic control apparatus (36) controlling the system operation according to routines stored in a memory (363) thereof; and a plurality of functional modules (14, 16), configured to be inserted into module receptacles, arranged on at least one weighing chamber wall (28). The at least one weighing chamber wall (28) is designed as a carrier structure, with recesses (283) which constitute clearances occupying a majority of the wall surface and which form the module receptacles. Either the functional modules (14, 16) or diaphragms (15) without a weighing function close the recesses and are spatially adapted to the recesses.
