FA1004B-2204B series 1/10,000 electronic analytical balance is developed by using electromagnetic balance sensor technology. It has the characteristics of high precision and strong environmental adaptability, as well as linear four-point calibration, counting function and various units. conversion, etc. The traditional classification element circuit board is changed to a large digital integrated type, which makes the performance of this series of electronic balances more stable, and the response speed is faster. At the same time, it has the functions of adjustable integration, stability and sensitivity. It connects the weighing plate with the energized coil and places it in the magnetic field. When the object to be weighed is placed on the weighing plate, due to the downward gravity, an electromagnetic force will be generated on the coil, which is equal in magnitude and opposite to the direction of gravity. At this time, the sensor outputs an electrical signal, which is rectified and amplified to change the current on the coil until the coil returns, and its current intensity is proportional to the gravity of the object being weighed. And this gravity is produced by the mass of the material, and the resulting electrical signal will display the mass of the item being weighed after passing through the analog system.
