4.1 Application
The TDS controller with limiting function FARB2 is used for continuous monitoring of the conductivity
of liquids.
The conductivity is measured with a measuring cell. This consists of a special conductivity probe and
the container wall or protective tube.
The conductivity is displayed via a 4*7 segment display and an active 4..20mA output interface. A
relay (SPDT) is provided for limiting or switching functions.
The requirements of EU Directive 2014/68/EU, the standards EN 13445, EN 12952-11 and
EN12953-9, EN 61010-1, EN 61326-1 are taken into account.
