Details:
Ordering note for capacitive vessel:
For attachment to GAS 222.11 / 30 / 35-U, a support is required.
Ordering note for pneumatic actuator:
If a blowback controller is required, only actuator P/N 46222030 is possible.
We advise the installation of a position indicator switch to control the pneumatic actuator.
Integrated blowback controller in the probe controller
In addition to the stand-alone blowback controller (RRS), an integrated blowback controller is optionally
available
Blowback cycle time and actual blowback time can be adjusted via the keys and menu of the controller.
The blowback and manual operation will be shown on the display. The blowback controller can be
programmed via the keys – manual or automatic operation is possible. Besides the status output of the
controller, a blowback status signal is provided. Blowback will be usually initiated by signals coming from
the main controls.
If the position indicator switch is installed, the controller will use this input for the process logic.
