Digital analytical balances utilize advanced technology, including a digital display and internal electronics, to measure the mass of an object with high precision.
Tips: How Does Electronic Analytical Balance Work?
An electronic analytical balance is a highly accurate weighing instrument used in scientific laboratories. It operates on the principle of electromagnetic force compensation. The balance consists of a weighing pan where the sample is placed, and beneath it, there is an electromagnet and a coil assembly. When the balance is turned on, the electromagnet generates a magnetic field that acts on the coil. The coil is attached to the weighing pan and moves vertically in response to the weight placed on it. As the coil moves, it generates an electric current proportional to the weight. This current is fed into a control system that adjusts the magnetic field strength to nullify the coil's movement, achieving balance. The control system calculates the weight based on the amount of current required for balance, providing highly accurate measurements.
