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 fixed 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 influences, such as dirt or moisture during storage.
