General safety instructions

1 General safety instructions

− The device must be mounted, started up or serviced by fully trained and

qualied personnel only; the accepted industry codes and practices are to

be observed. Make sure employees or third persons are not exposed to any
danger.

− According to these mounting and operating instructions, trained person-
nel refers to individuals who are able to judge the work they are assigned
to and recognize possible dangers due to their specialized training, their
knowledge and experience as well as their knowledge of the applicable
standards.

− To ensure appropriate use, only use the device in applications where the op-

erating pressure and temperatures do not exceed the specications used for

sizing the regulator at the ordering stage.

− The manufacturer does not assume any responsibility for damage caused by
external forces or any other external factors.

− Any hazards that could be caused in the controller by the process medium,
operating pressure or by moving parts are to be prevented by taking appro­priate precautions.

− Proper transport, storage, installation, operation and maintenance are as-
sumed.

− SAMSON does not assume any liability for damage caused when the device
is not used as intended.

Process medium and scope of application

2 Process medium and scope of application

Pneumatic controller functioning as a proportional controller to control the temperature of gases
and vapors at the point of measurement with a pneumatic control valve.

Medium temperatures from 0 to 300 °C

The controller compares the temperature measured by the xed expansion bulb sensor with the
adjusted set point and issues a pneumatic signal between 0.2 to 1bar at the output. This signal

pressure acts on the connected pneumatic control valve. The controller requires a supply pres-

sure of 1.4bar. The measured temperature is indicated at the controller.

2.1 Transportation and storage

Transportation and storage in the permissible temperature range from –10 to +90°C. Protect
the controller against adverse inuences, such as dirt or moisture during storage.

2.2 Versions

Two versions of the Type3301 Controller are available that have different set point ranges.
