Abstract: Abstract:A metrical information collecting circuit with antiinterference function used in cement balance weight manufacturing was introduced. Using the circuit, the metrical common interference signal and electromagnetic interference signal can be prevented, the signal transmission way can be simplified, the error of the metrical signal can be avoided, and the accurate transmission of the metrical signals was ensured. So the technical difficulty in metering and control of cement balance weight manufacturing for the ship lift of Three Gorges project was solved, and the technical level of the balance weight manufacturing was raised.

Key words: Keywords:Three Gorges project, cement balance weight, common mode interference, signal filtering, information collecting circuit
