Beckhoff Automation em3701

The EM3701 analog input terminal measures the differential pressure between two hose connections in a measuring range of ±100 mbar. The pressure value is directly available to the controller as a 16-bit value, and errors such as out-of-range values are also displayed. The compact design and simple connection system support space-saving and quick installation with no need for additional measuring devices. The terminal can be used to measure pressure or also to replace a pressure switch. It is not suitable for measuring aggressive gases. The pressure value in the controller enables the switching threshold to be stored as a parameter for a logical operation. Manually setting the pressure switch in the application is therefore no longer required.   Special features: direct differential pressure measurement in the ±100 mbar measuring range pressure range overflow display compact design and simple connection technology can be used as a replacement for pressure switches   The EM3701 belongs to the EM37xx series of pressure measuring terminals. These are split into two groups: differential pressure measurement (measurement between two terminals) and relative pressure measurement (measurement relative to the environment).
