7. Product description and
accessories

• The device offers high-precision measuring of

chlorine, chlorine dioxide and ozone.

– comprehensive limit value functions
– comprehensive alarm functions
– error message function for indication of

non-functioning sensors.

7.1 General description

The Conex® DIS-G is a gas warning controller for
monitoring gas concentrations, for example in
storage or dosing rooms. With a maximum of two
independently connected sensors, the gas
concentration of chlorine, chlorine dioxide or ozone
can be displayed and monitored.
Amperometric sensors (sensor discs) are connected
directly to the Conex

®

DIS-G.

The sensor Cl

2

/ ClO2 does not provide selective
measurement. In case both substances are present,
the measured value includes both.

The measuring parameter does not have to be set in
the software (or device). It is selected using the
corresponding sensor.

Each of the two sensors is provided with electrically
isolated current outputs to output the measured
concentration, two electrically isolated limit value
transmitters and an alarm relay to control the
warning and safety equipment.

The Conex

®

DIS-G meets high safety requirements
through permanent sensor monitoring and alarm
relays.

How the system operates

• The gas sensors generate a current proportional

to the gas concentration in the air.

• The Conex

®

DIS-G gas warning controller
– amplifies the sensor current
– triggers an initial warning, for example when

the first limit value is exceeded

– activates the relevant warning and safety

equipment when the second limit value is
exceeded

– outputs the measured concentration at both

sensors as a 0 (4)-20 mA signal via the current
outputs (for example for recording).
