Beckhoff EM3702 | EtherCAT Terminal, 2-channel analog input, relative pressure

The EM3702 analog input terminal measures the pressure value as a difference

to the environment (relative pressure measurement) in a measuring range up

to 7.5 bar. 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 a measuring range up to 7.5 bar

• pressure range overflow display

• compact design and simple connection technology

• can be used as a replacement for pressure switches

The EM3702 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).
