    摘要: Systems and methods for electronic scale auto-zeroing. One example system includes a load cell coupled to a platform of the scale and an electronic processor coupled to the load cell. The processor is configured to receive an activation command activating the scale and, responsive to receiving the command, initiate a powerup zeroing function. The processor is configured to receive, from the load cell, a first signal indicative of a force applied to the platform and, responsive to receiving the first signal, determine whether the force applied to the platform of the scale exceeds a threshold. The processor is configured to, responsive to determining that the force exceeds the threshold: cancel the powerup zeroing function, and calculate a weight based on the first signal. The processor is configured to, responsive to determining that the force does not exceed the threshold, complete the powerup zeroing function.

    摘要: The invention discloses an electronic balance comprising a measured value receiver (23) and an electronic evaluation unit (14) having a digital display (10) and an analog display (6), whereby both displays are controlled by the electronic evaluation unit (14). A digital input keyboard (12) is used for inputting the set weight value of a loading. The electronic evaluation unit (14) contains a memory (15) and an arithmetic unit (16) which permit the values indicated in the digital display (10) and in the analog display (6) to be differentiated against each other by the amount stored in the memory (15) so that during a loading procedure the digital display (10) runs from the negative set weight value to 0g and the analog display (6) from 0% to 100%. The analog display (6) consists of adjacent bars (7) which can be shited in their lightness, whereby the length of the individual bars continuously decreases from 0% to 100% of the set weight value, and continuously increases again over 100% of the set weight value.

    摘要: This invention relates to a photoelastic load measurement device which measures the load on the cable of the crane by measuring the strain in a particular structural member of the crane and is calibrated to operate an alarm, indicator and/or recorder. A source of polarized light directs a beam of light through a photoelastic plate to an analyzer plate and a photocell. The photoelastic plate is subjected to stress from the structural member which varies with the load on the cable of the crane. The stress in the photoelastic plate subjects the beam of polarized light to temporary double refraction (birefringence), and the intensity of the light received by the photocell through the analyzer plate is dependent upon the degree of retardation of the light in the photoelastic plate. The output signal from the photocell is amplified to operate the alarm, indicator and/or recorder. The device includes apparatus which automatically compensates for changes in ambient temperature and variations in boom angle.

    摘要: A weighing scales has a base and a platform supported by the base and adapted to support an individual. A transmission mechanism within the base is responsive to movement of the platform for causing pivotal translation of a graduated transparency. A beam of light from a light source is projected along an optical path through the transparency and reflected to a projection screen carried by the platform for read-out of weight. The light source is carried on a support plate which is mounted to the base by means disposed at two points on a line at least substantially parallel to the optical axis and coincident with the optical axis substantially at a fixed axis of the graduated transparency. The transparency is pivotally mounted on the support plate and presents a convex face toward the light source.

    摘要: The helical tension spring which counteracts the weight of an object on the scale pan of an inclination balance is fixedly attached to one arm of the balance beam to avoid friction in the connection between the spring and the beam. The attachment permits the spring position to be adjusted along the beam and the effective length of the spring to be adjusted. The weighing errors resulting from buckling of the spring are compensated by a suitably modified scale from which the weight is read.
