Electromagnetic balance

Abstract

Provided is an electromagnetic balance. The electromagnetic balance comprises a circuit, a coil, supporting belts and magnets. The circuit is connected with the supporting belts through a lead a and a lead b, the supporting belts are connected with the coil, the coil is arranged between the magnets, a balance rod is connected to the coil, a measurement hook and a weight hook are arranged at the two ends of the balance rod respectively, the measurement hook is connected to a measurement pan, the weight hook is connected with a scale pan, an observation strip is arranged at one end of the balance rod provided with the measurement hook, a fluorescent screen and a light source are arranged on the two sides of the observation strip respectively, the balance rod is made of insulation plastic, and the magnets have upper poles and lower poles. The electromagnetic balance has the advantages that the electromagnetic balance is simple in structure and convenient to manufacture, electromagnetic force is utilized to replace a balance knife edge to carry out supporting, the abrasion phenomenon is avoided, the accuracy of measurement data is ensured, the service life of the balance is greatly prolonged at the same time, many unnecessary troubles are reduced for a user, and therefore, the electromagnetic balance is easy to popularize.

Description

technical field [0001] The invention relates to a balance, in particular to an electromagnetic force balance. Background technique [0002] At present, the tray balance usually includes a base, a tray weighing sensor, an operation panel, a display, etc., among which, the size and specification of the tray are consistent with the model of the balance. The most critical part in the tray balance is the knife edge. After a long time of use, the knife edge Wear and tear will lead to inaccurate measurement data, bring a lot of trouble to the measurer, and also limit the service life of the pallet balance, so an improved technology is urgently needed to solve the above technical defects. Contents of the invention [0003] The invention provides an electromagnetic force balance. [0004] The technical scheme that the present invention proposes for above-mentioned technical defect is: [0005] An electromagnetic force balance, including a circuit, a coil, a support band and a mag...
