OPTIMIZATION OF THE STRUCTURE AND ALGORITHM OF THE WORK OF THE HIGHLY-SENSITIVE MULTI-SENSORS SYSTEM WITH IMPEDANCE TRANSDUCERS
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2018, Vol 15, Issue 4
Abstract
The paper considers the new method of parallel-sequential transformation of signals for multi-parameter studies of fast processes using highly sensitive multi-biosensor systems. The developed solution allows to obtain 18-bit results with a frequency of 100 Hz, with asynchrony of samples of the measured values no worse than ± 3,3 msec, high sensitivity and suppression of interference on the frequency 50 Hz. The structure and algorithm of operation of the unified three-channel measuring unit based on AC-bridges with using the integrating type ADC MAX-132, which are developed at the Institute of Electrodynamics of the National Academy of Sciences of Ukraine, are considered. The proposed measuring channel can be used in a single-channel mode with any of three sensors with three-fold increase in the sampling frequency.
