Page 6: Function
PM11 Electronic pressure sensor 4 Function Measuring cell: • The system pressure is measured by a ceramic capacitive measuring system. • The sealing of the ceramic measuring cell is free of elastomers and thus maintenance-free. Signal transmission: • The unit can be operated in analogue mode and in IO-Link mode. When connected to an IO-Link master, the unit automatically switches to IO-Link mode. -

Page 9: Installation
Electronic pressure sensor PM11 5 Installation The device can be adapted to clamp connections 1“ – 1.5“ [DIN 32676 (ISO 2852)]. Before installing and removing the device: Make sure that no pressure is applied to the system and there is no medium in the pipe. -
Page 10: Use In Hygienic Areas According To 3-A
PM11 Electronic pressure sensor 5.1 Use in hygienic areas according to 3-A The following applies to devices with 3-A certification: u Only use adapters with 3-A certification for the process connection. u Do not install the device in the lower section of the pipe or tank (positions 4 and 5) in order that the medium can run off the area of the measuring element. -
Page 11: Orientation Filter Cover
Electronic pressure sensor PM11 For a correct functioning of the ventilation diaphragm please take the following into account: u Remove soiling and cleaning agents immediately using plenty of lime-deficient splash water. If the sensor is in a cooling stage: u Avoid contact of the ventilation diaphragm with liquids to avoid negative pressure in the measuring system (resulting in a slightly falsified measured value) and additional strain on the diaphragm. - Page 12 PM11 Electronic pressure sensor u Avoid soiling and moisture during the exchange u Clean the thread carefully and without residues. u Do not damage the adhesive surface for the diaphragm on the sensor. u Observe the orientation of the filter cover (Ò Installation instructions E30139 / E30467).
