An electronic analytical balance for mass determination

Abstract

The invention relates to the technical field of electronic analytical balance, and discloses an electronic analytical balance for mass measurement, which includes a body, the outer side of the upper surface of the body is fixedly connected with a windshield box, and the upper surface of the body is located at the top of the windshield box. A weighing pan is arranged inside, and an anti-convection ring plate is movably sleeved inside the body. The electronic analytical balance used for quality measurement, through the cooperation between the linkage device, the control device and the balance device, when measuring the mass, when there is a temperature difference between the actual temperature and the measured temperature, the magnetic induction intensity and the effective length of the magnetic induction coil increase. The volume of the thermally sensitive balloon on the left contact plate is increased, changing the angle between the horizontal plane of the magnetic induction coil and the linkage device, so that the sine value of the corresponding angle becomes smaller, which is beneficial to keep the gravity of the measured object on the weighing pan in line with the corresponding The electromagnetic force is still proportional, which effectively reduces the influence of inaccurate measurement of the mass of the object, and improves the accuracy of the mass measurement of the mass of the electronic analytical balance used for mass determination.

[0005] The invention provides an electronic analytical balance for mass determination, which has the advantages of improving the accuracy of the electronic analytical balance for mass determination in measuring the quality of articles, improving the electronic analytical balance for mass determination to protect internal electrical components and reducing the The advantage of the warm-up time of the electronic analytical balance solves the problem that when the actual temperature of the electronic analytical balance is different from the temperature required for measurement, when the existing electronic analytical balance is weighing, the results displayed by the electronic balance and the normal weighing are inconsistent. It is necessary to adjust the actual temperature to the measurement temperature range by preheating in advance. During the preheating process, the time is generally one hour or even two hours. However, if the preheating time is too long, it will cause damage to the internal electrical components of the electronic balance. , not only the warm-up time is longer, which reduces the timeliness of quality measurement, but also needs to prevent the problem that the warm-up process may damage the internal electrical components of the electronic balance
