B&B Electronics QSU2-540IS industrial four-port USB to RS-232 serial adapters with optical isolation are being used as part of a real-time reaction analysis system. The system is designed to both identify reactants, products and intermediates in a chemical reaction and to track the course of the reaction with a single automated system. The system is comprised of four reactors, each of which can be individually controlled and conditioned, with a probe integrated into the base of each. Modulated infrared radiation is passed to each of the reactors in turn, and a spectrum is measured and passed to a Windows 7 based PC via a serial to USB interface. Up to thirty spectra per hour are obtained from each reactor and used by the system to derive concentration profiles.B&B Electronics' QSU2-540IS is used by a major natural gas producer to implement a well monitoring system. Each well is monitored by an electronic gas meter. Each group of wells uses telemetry and a master radio to transmit data. Each master radio requires a dedicated serial port on the polling computer, and B&B Electronics' QSU2-540IS provides the additional serial ports required.
