Pulse generator for electric meter

The utility model discloses a pulse generator for an electric meter. The utility model is composed of a pulse generating circuit, a pulse processing circuit and a photoelectric coupling output circuit. The pulse generating circuit comprises a metal sheet A, electrical inductance L, capacitance C1, a resistance R2, a resistance R3 and an integrated circuit IC 1 of a proximity switch. The metal sheet A is fixedly connected with a rotary plate of the electric meter. After the electrical inductance L and the capacitance C1 are connected in parallel, the electrical inductance L and the capacitance C1 are connected with the 12 pin, the 13 pin and the 6 pin of the integrated circuit IC 1. The resistance R2 and the resistance R3 are respectively connected between the 14 pin and the 2 pin of the integrated circuit IC 1, and the 11 pin and the 5 pin of the integrated circuit IC 1. The 5 pin of the integrated circuit IC 1 is connected with an output terminal of the pulse processing circuit. The utility model can be widely used for the electric meter.
