The compact pressure transmitters of the 21Zio series can be used either as a pressure measuring instrument or as a pressure switch. Thanks to the universal IO-Link interface according to IEC 61131-9, the sensor is flexible and easily and quickly integrable into intelligent automation and other systems. The switching functions and other parameters can be called up and configured directly via IO-Link. In this way, machine downtimes are reduced to a minimum and personnel are relieved.
