B-8 Pressure sensor
B-8.1 Type CT30
Only one of these pressure sensor types can be connected to the EK220.
The first pressure sensor can be implemented either as internal or as extern al version and
is available only as an absolute-pressure sensor.
The second pressure sensor is connectable only as external version and can be impl e-
mented as an absolute or relative pressure sensor.
Pressure connection: Ermeto M12 x 1.5 male thread, usable length approx. 10 mm

B-8.3 Installation information
When connecting the pressure line to the installed pressure sensor, attention must be paid
to the pipe diameter to avoid damage and leaks on the gland connection. In particular the
parting point on the pipe should be checked for burrs or flaring, which cause an increase in
the outside diameter of the pipe.
