EM3701 | EtherCAT Terminal, 1-channel analog input, differential pressure, ±100 hPa (±100 mbar)

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).
