EXmatic 470 is an electro-pneumatic control unit for fully automatic control of pneumatic retractable housings of EXtract 8XX series. The integrated connection hose accommodates all control tubes and makes the installation very easy.The combination of the control unit EXmatic 470 and a retractable probe housing of EXtract 8XX series ensures safe access to a sensor by driving it easily out of the process into the maintenance position and clean them fully-automatic with different rinsing solutions or even to take out the sensor for inspection, calibration or exchange. The cleaning intervals as well as additional functions can be programmed very easily. Output contacts can be connected to a DCS for external start and monitoring. It is an open and autonomous system and does not depend on any specific sensor transmitter.
