摘要： A precision balance including a weighing chamber (16); a draft shield (18, 20, 22), which surrounds the weighing chamber (16); a climate module (34), which is detachably disposed in the weighing chamber (16); a processor (32) and a data input unit, which both form part of the overall precision balance; and a data transmission path, over which data is exchanged between the climate module (34) and the processor (32). Also disclosed is a climate module for a precision balance. The climate module (34) forms a self-contained modular unit and includes an air pressure sensor (62), an air humidity sensor (54) and an air temperature sensor (52) The climate module also includes a data transmission path configured to transmit data to a processor external to the climate module, and a mounting mechanism configured to secure the climate module detachably to a weighing module (10).

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.

摘要： An electromagnetically force-compensating force-measuring apparatus (100) that includes a force dependent support coil (2) and an integrating analog/digital converter (10; 10′) that converts the coil current (IS) into a digital output signal. A current/voltage converter (6) is connected downstream of the support coil (2), the output of the current/voltage converter being connected to a measurement voltage input (14) of the analog/digital converter (10; 10′) and to the input of a voltage amplifier (8). The resistance value of a first heating resistor (RSH) is equal to the resistance value of the support coil (2), the resistance value of a second heating resistor (RWH) is equal to the conversion factor (RW) of the current/voltage converter (6) and the gain factor of a voltage amplifier (8) is equal to the ratio of the resistance value of the first heating resistor to the resistance value of the second heating resistor.

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′).
