摘要： A balance (30) is a single unit with a weighing pan (21) enclosed in a weighing compartment (22). A housing (23) adjoins the weighing compartment. The balance housing contains a weighing cell compartment (24) enclosing a weighing cell, an electronics compartment (25) containing electrical and electronic circuit elements, a thermoelectric heat pump module (27) and a heat flow controller (28). The balance is equipped to determine a net heat flow (Pnet) inside the housing in the direction from the weighing cell compartment to the electronics compartment. The heat flow controller uses the net heat flow as a control input to regulate the the thermoelectric heat pump module, arranged inside the housing. The control input is used to generate an active heat flow (PA) with magnitude and direction for holding the net heat flow at a level equal to the rate of heat dissipation produced inside the weighing cell compartment.

摘要： To provide a weighing apparatus by which it is possible for a user himself/herself to determine poor performance of the apparatus is a factor attributable to an installation environment, and the weighing accuracy is improved. Respective temporal fluctuations in weighed data detected from a load measuring mechanism 2 and environmental measurement data detected in an environmental measurement means 10 are recorded in a correlative manner in an arithmetic processing unit 32, and the temporal fluctuations are visually recognizable via a display unit 31. Thereby, the correlation between the environmental variations and the weighed data is visually disclosed, which makes it possible for a user to easily recognize that poor performance of the apparatus is attributable to the environmental variations, that increases the reliability of the weighing apparatus. Further, the fundamental performance (accuracy) presented by the apparatus is also assured by allowing the user himself/herself to improve the surrounding environment.

摘要： A weighing cell based on the principle of electromagnetic force compensation. A permanent magnet system is mounted on a base part and includes an air gap within which is suspended a coil that is connected to a load receiver through a force-transmitting mechanism. The coil carries an electrical compensation current when the weighing cell is in operation. An optoelectronic position sensor is also included, and its signal corresponds to the deflection of the coil from a zero position which occurs as a result of placing a load on the load receiver. A closed-loop controller regulates the compensation current in response to the sensor signal in such a way that the coil and the load receiver that is connected to it are returned to their zero position by the electromagnetic force that is acting between the coil and the permanent magnet.

摘要： A belt weighing apparatus for maintaining high accuracy in weighing by way of maintaining a fixed tension in the belt and preventing the belt from oscillating. The belt conveyor is comprised of a supporting frame, an upper guiding unit arranged on the supporting frame, a first and a second end-supporting device arranged on the supporting frame in proximity to the opposite ends of the upper guiding unit, a motor unit, at least one weighing platform arranged in-between the first and a second end-supporting devices, a lower guiding unit having a first property arranged on the supporting frame, and an endless conveyor belt having a second property is extended between said first and a second end supporting devices. At any instant of time an upper part of the belt rests on the upper guiding unit and the weighing platform defining a conveying pad of the belt weighing apparatus, and the lower part of the belt defining the return way of the belt weighing apparatus rests partly on the lower guiding unit that acts as a support for part of the lower run while another part of the belt hangs freely. The accuracy in the weighing is maximized by matching the first and the second properties such that any heat expansion or contraction of the belt will be compensated at least partly through expansion or contraction of the lower guiding unit.

The deformable body connects a housing-mounted fixed part to a force-introducing part of the force transducer. The sensors are connected to electrical conductors of at least one flat ribbon cable which leads to a circuit module that serves to process the measuring signals and contains the connections for joining the sensors together in a measuring bridge circuit. The conductor tracks can be configured so that all of the connecting leads from nodal points of a measuring bridge to the contact terminals of the sensors have at least approximately equal resistance values.

摘要： In an automatic thin-film measuring apparatus, the zero point of a precision balance is corrected according to directions from a data processing unit before and after the weight of a semiconductor substrate is measured, the surface temperature of the semiconductor substrate laid on a pan of the precision balance is measured, and the weight of the semiconductor substrate is measured when the surface temperature reaches a predetermined value. Furthermore, the cycle of variations in the zero point is found when the zero point is corrected, and the weight measurement of the semiconductor substrate is conducted during an integer multiple of the change cycle. Therefore, it is possible to enhance the precision of the weight measurement and its reproducibility and to shorten the measurement time without being influenced by low-frequency vibrations.
