Beckhoff EM3712 | EtherCAT Terminal, 2-channel analog input, relative pressure

The EM3712 analog input terminal measures the pressure value as a

difference to the environment (relative pressure measurement), in the

measuring range of ±1 bar. This means that negative pressure values

are also permissible as a difference to the environment. 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 relative pressure measurement in the measuring range of ±1 bar

• pressure range overflow display

• compact design and simple connection technology

• can be used as a replacement for pressure switches

The EM3712 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).
