1.1 Task and fields of use
HYGROPHIL ® H 4230 is a measuring system for determining the amount of
water vapour in air and other gases.
In many processes, monitoring and controlling gas humidity is a must if you
want to achieve a consistently high product quality, use energy efficiently
and adhere to the regulations regarding emission limits.
HYGROPHIL
®
H 4230 is a special measuring unit for measuring humidity
under extreme measuring conditions such as:
 High measurement gas temperatures

Gas humidity up to saturation

Significant contamination in the form of dust, oil, grease, external gas and
solvents, also in highly corrosive form.
Being a high-end device, HYGROPHIL
®
H 4230 is particularly suitable for
continuous industrial use.
HYGROPHIL
®
H 4230 also makes it possible to measure humidity in pro-
cesses during which this is otherwise not continuously possible or can only
be done using laboratory methods, if at all.
HYGROPHIL
®
H 4230 uses a microprocessor to calculate all humidity-
related variables in various scales and, in addition, to automatically monitor
the unit itself. As a result, maintenance is minimized.
Thanks to its special features, HYGROPHIL
®
H 4230 can be used in places
where other measuring systems fail due to unfavourable ambient conditions.
Examples include:
 Flue gas measurement in power stations

Flue gas measurement in incineration plants, even before filtering
 Fabric processing facilities
 Hot-air tunnels for preparing fast food

Ovens

Roasting facilities
 Copper extraction facilities, even subject to contamination by sulphuric ac-
id

All types of raw material dryers

Sintering facilities for ores
The response rate of the measuring system guarantees that an appropriate
closed-loop control can be operated in all application cases.
HYGROPHIL
®
H 4230-12 is explosion proof. It can be used in hazardous
zone II area. To guarantee the explosion protection is the enclosure continu-
al perfused by a scavenging gas. The scavenging gas flow is monitored and
controlled.
The rinsing is intended for gases which have a higher density than the scav-
enging gas.
