Gas warning unit for chlorine, chlorine dioxide, ozone, ammonia and hydrochloric acid
Optimum safety - minimum labour input: The Conex DIA-G safety system monitors the
concentration of the gases chlorine, chlorine dioxide, ozone, ammonia and hydrochloric
acid in the air of storage rooms. It is equipped with a range of functions providing the
users with optimum safety combined with minimum labour input. One unit can use two
interconnected sensors to monitor two different gases, two different gas concentrations
or two different gas storage rooms in parallel.

Features & Benefits:
|
|
|
Optimum safety: Thanks to permanent sensor monitoring,
the alarm relay and the possibility of backup operation
(uninterrupted current supply) by connection of an external
buffer battery
|
|
|
|
Very short response time in case of a sudden change
of the gas concentration
|
|
|
|
Long service life of the sensor element -
without necessity of maintenance
|
|
|
|
Sensor recognition and auto-calibration,
monitoring of the lifetime of the sensor
|
|
|
|
Internal CAN bus interface for the connection of
potentiostatic sensors using Bus lines with a total
length of max. 500 m
|
|
|
|
External CAN bus interface for the connection of Conex
DIA-G to the visualising software AquaVision 2 or to PLC
