2 SPECIFICATION
Redox transmitter 8206, remote
The redox transmission system combines a redox sensor 8200, and a separate redox trans-
mitter 8206 with display.
The 8206 remote transmitter is available in panel-mounted version or in a wall-mounted
enclosure for connection to the redox sensor 8200.
Redox sensor 8200
A redox sensor is necessary for use with the redox transmitter 8206 separate.
The redox sensor 8200 for redox transmitter 8206 separate version can be easily installed
into pipes using our specially designed fitting system (S020).
Please refer to the redox sensor 8200 instruction manual.
Measuring Principle
When a redox potential electrode is immersed in a solution an electron exchange occurs
between the oxidised and the reduced state of the electrolyte.The generated cell voltage is
the redox potential.
The transducer without relay functions in a 2-wire circuit and requires a power supply of
12...30 VDC (or 115/230 VAC as an option in Wall-mounted version). A 4...20 mA stan-
dard signal is available as output signal, proportional to the redox potential
(cf § 4.3.2).
The transducer with two additional relays functions in a 3-wire circuit. Limit values are freely
adjustable (cf § 4.3.3).
