Electronic module for control of sample feeding device of spectrometers of X-ray fluorescent analysis of CRV type

The scheme of electronic module for sample feeding device control for the CRV type X-ray fluorescence analysis spectrometers is considered. This module provides realization of next functions: sample change operations and installation in starting position; signaling and defense at emergency cases; indication of any sample amount in the spectrometer chamber; testing function at tuning and testing of modules. All these principal functions are entrusted with microcontroller. Programming of the microcontroller is putting into effect by algorithm of the whole sample feeding device. In the capacity of microcontroller the single crystalline processor PICI16C54 and stepping motor of NV-306-V2202 model have been used
