OverviewEXmatic 471 is an electro-pneumatic control unit designed for fully automatic operation of pneumatic retractable probe housings of the EXtract 8XX series. In combination with an EXtract 8XX housing the unit drives sensors out of the process into a maintenance position for automatic cleaning, inspection, calibration or replacement. Cleaning cycles and additional functions are programmable. Output contacts allow integration with process control systems for external start and monitoring. EXmatic 471 is an open, autonomous system compatible with any transmitter.
