2.3 Design and measuring principle

Design
pH controller 8205 compact
The pH-controller compactly combines a
pH-sensor and a controller with display in a
splash-proof enclosure.
The sensor component consists of a
replaceable combination pH-electrode,
screwed into the sensor housing with
screw-in threads. The measured signal is
conveyed to the controller via a coax plug.
The Pt1000 for automatic temperature
compensation is a standard feature in the
sensor housing.
The controller component converts the
measured signal, displays the actual value
and computes the command signals.
The output signals are provided via two
cable glands.

pH controller 8205, separate version
The pH transmission system combines a
pH sensor 8200, and a separate pH
controller 8205 with display.
The 8205 separate controller is available in
panel mounted version or in a wall-
mounted enclosure.
pH sensor 8200
The characteristics of electrodes are
described in the 8200 operating
manual.The Pt1000 for automatic
temperature compensation is available as
an option feature in pH sensor housings
type 8200.
