摘要：

A design is presented in which a 24 bit sigma-delta ADC is combined with an Intel 8032 supervising microcontroller and a tuned zero-crossing detector to give a relatively simple and economical circuit that adapts to local line supply frequencies to maintain very high levels (>150 dB) of interference rejection. The design is particularly applicable to industrial sensors, including thermocouples, load cells, ion-selective and pH electrodes and chromatographic detectors.
