company news about What is the composition of the active high anti-jamming sensor for railway wheels?

The company has developed a special active high anti-jamming sensor for railway wheels, which belongs to a signal sensor, especially a railway wheel active sensor with an excitation source. It consists of a sine wave oscillator, a measuring bridge circuit, and a high common-mode differential amplifier. The signal output end of the sine wave oscillator is connected to the signal input end of the measuring bridge circuit, the signal output end of the measuring bridge circuit is connected to the signal input end of the high common mode differential amplifier, and the signal is output by the output end of the high common mode differential amplifier. The number of turns of each coil in the measurement bridge circuit is between 100 and 200 turns. The utility model has strong anti-interference ability, high sensitivity, strong stability, no error signal is generated, and the vehicle speed detection range reaches 0-360km/h. Can be used in electrified railway sections pulled by electric locomotives.
